Some people shouldn’t own cars Mike Mavrigian | Editor

e’ve all dealt with these types of customers from time to time. You know, the folks who amaze you with their vehicle ignorance. But since you’re a polite pro and don’t want to alienate anyone, you say nothing, just grin and bear it. (And then try to educate them.) Here are a just a few encounters that come to mind, experienced either by myself or an acquaintance who runs a shop.

(First of all, we all know that one thing has nothing to do with the other. In addition, you take the car for a test drive and she rides smooth as silk.)

“I’ve been sitting for over a half hour in your waiting room. The coffee stinks, your magazines are old and there’s nothing of interest on your TV. Why in the world does it take so long to change a simple belt?” (The job at hand involved replacing a timing belt on a cramped-engine-bay in a PT Cruiser.)

“The last time I was here you told me to check my tire pressure regularly. I followed your

“My dog keeps jumping up on my hood and scratching the paint. Do you have anything to prevent that?” (You’d love to tell her to position an angry skunk on the cowl, but you’re polite.)

“My uncle could replace those fuel injectors and fgure out why the battery dies all the time in an hour, and he wouldn’t charge me. I saw him change a carburetor on his truck once.” (On the inside, you tell her to take her piece of junk to her uncle and never darken your doorway again. On the outside, you politely explain that your skilled technicians should complete the job in about another hour, barring any other problems that they fnd during the diagnosis. Let’s pull the car into the shop now, miss.)

advice, and now the car rides kind of hard. It feels thumpy when I hit bumps.” (You check pressure only to fnd that he pumped up all of the tires to the MAX rating. When you ask why he infated all of the tires to 46 psi instead of the 34 psi that you recommended, he tells you that he assumed that anything that says “max” would be better. Grrr.)

“Ever since you did the oil change on my Kia Soul, the car rides really rough. I feel like I’m driving a truck.”

“I think there’s something wrong with my car. It’s hard for me to keep it steering where I want to go. I’m so afraid that

there’s something seriously wrong and it’s going to be expensive.” (You wipe the French fry grease from the steering wheel with a towel soaked with Dawn and water, rinse and dry, and tell her to have a nice day. “No charge, ma’am.”) “My car keeps leaking oil, and I’m tired of checking the dipstick. So until I could bring the car to you, I played it safe and poured in a whole 10 quarts, which I fgured would

be plenty to get me by until I came here. Oh, by the way, now the car makes strange sounds, too, and it’s getting worse.” (Can you say rod and main bearings?) “I just bought a 1964 Ford Fairlane, all restored. Great paint job. Thought it would be great to have a car to drive to car shows, like some of my buddies. But it rides lousy, the steering feels loose and the brakes are terrible. My new BMW rides so much nicer than this.” (Hey, pal, it’s not a new BMW. It’s a 49-year-old Ford. You need to collect stamps instead of cars.) “My dad keeps telling me that I don’t know how to drive a stick. Boy, is he dumb. My car has a stick and I don’t have any problems at all.” (Yep, the automatic trans in her car has a console-located straight shift lever with a ball on top.) Editor’s note: I really wish I had made this up. ●

Readers offer solutions to tricky problems Hello, Mike, I read your ozone generator article in the May/June 2013 issue and agree with their effectiveness. I’m a late model used car dealer (after 40 years selling GM and Chrysler) and I have been using ozone machines for 30-plus years. The worst case I’ve dealt with was a new Chevy Colorado a lady brought in. She always takes her dog with her wherever she goes. Well, the dog tangled with a skunk, and before she realized what had happened she opened the rear door and the dog jumps in as usual! Peeeeeew! Our ozone machine got rid of the skunk odor. I’d like to pass on a tip to you and others. I put a trickle charger to the car battery (two amp), and turn on the A/C to recirculate, put the fan speed on high, while the ozone machine runs. This purifes the A/C duct work system, too. I would also suggest replacing the cabin air flter, if so equipped. Thanks for a great magazine! Monty Hamilton, Owner Hamilton Auto Sales LLC Greenville, Ohio

Hi, Mike, Concerning the TSB recently posted on www.autoserviceprofessional.com about a Honda EVAP MIL, Honda reported 20062011 Civic models except Si and GX may exhibit an MIL with DTC P2422 (EVAP canister vent shut valve stuck closed malfunction). The probable cause involves spider webs clogging the EVAP canister vent tube. The corrective action requires replacement of the EVAP canister vent tube. Down here in the South there’s a wasp called the mud dauber. These little things can build a nest as big as a baseball before you realize what they’re up to. They’re not at all claustrophobic.

Recently I grabbed my mechanic’s stethoscope to listen to an engine noise. Both sides of the stethoscope were inoperative. I took the thing apart piece by piece looking for the reason why both sides wouldn’t work. I fnally got to the “Y” pipe that joins the two ear tubes together. I found the bottom leg of the “Y” packed full of dry, hardened mud thanks to a mud dauber. I couldn’t believe it. This is a distance of nearly two feet the wasp had to crawl with wet mud in its jaws through a tube about 1/8-inch in diameter. He then had to crawl out of the tube backwards the same two feet to get out. Unbelievable, to say the least. If a spider can clog an EVAP hose, imagine what a mud dauber could clog up. Don’t let your car sit in one place for very long if there are mud daubers nearby. Allan Boggs, Owner Allan’s Auto Repair New Orleans. La.

Hi, Mike, Re: “Tricky Honda” TSB on your website. You wrote that Honda reported engine knocking or ticking at idle, with the noise usually more noticeable when the engine is warm. Affected vehicles include 2008 Accord V6 with automatic transmission, 2008 Odyssey EX-L/Touring and 2009 Pilot 2DW and 4WD vehicles. The corrective action involves loosening and re-torquing the rocker shaft bridge bolts. (See page 67.) I get a lot of questions about this problem and how to solve it from my Honda Accord forum members. This TSB will answer a lot of those questions. We all thank you. Angelo A. Gillono, Owner The Wheel Broker Massillon, Ohio Be sure to check out our website for the latest TSBs, news, technical articles and products (see www.autoserviceprofessional.com).

Catalytic converter diagnosis Converter ‘failure’ is often caused by upstream or damage issues Compiled by Mike Mavrigian

can fail, but more often than not, the root cause might involve upstream components such as an O2 sensor, fuel injectors, spark plugs, EGR valve system, exhausts manifolds, vacuum hoses and MAF sensors. Thermal failures: Although modern three-way converters (TWC) can withstand short exposures to 2,000 degrees Fahrenheit, engine exhaust conditions caused by failed or out of tolerance parts can push temperatures above the converterâ&#x20AC;&#x2122;s operating limit. Excessive rich fuel conditions and exhaust leaks ahead of the converter Engine running too hot. are prime examples. They result in higher than normal temperatures that can cause matting erosion and burn away or melt converter coatings. If temperatures are high enough, the ceramic substrate itself will melt and clog. Contamination: If silicone products are used to seal any part of the exhaust system including the exhaust manifold and gaskets, O2 sensors, and exhaust tubing, youâ&#x20AC;&#x2122;ve got problems. At best, the highest rated silicone can only handle 700 degrees F, so when Engine oil entering exhaust. exposed to exhaust temperatures of 1,200 degrees F, it quickly burns and outgases, leaving a silicone coating on the O2 sensor or converter wash coating. The results include engine conditions that are out of operating range and reduced effciencies within the catalytic converter. Coated or fouled: Anything that gets through the combustion chamber and reaches the face of the converter can reduce catalyst effciency. Liquids such as antifreeze from leaking manifolds and oil from head gasket failures top the list of troublemakers. Engines in need of service and older engines that burn oil due to worn cylinder walls, stuck rings, and worn valve guides will produce by-products that can foul the converter.

diagnosing and evaluating catalytic converter problems has to be at top of the list. One of the most annoying problems is the persistent P0420 diagnostic code (Catalyst System Effciency Below Threshold (Bank 1), which not only shows its teeth when the catalytic converter is on the blink, but can also be generated by a variety of engine problems not directly related to the converter.

Chasing P0420 codes One of the most annoying challenges to emissions service has to be the persistent P0420 code. Although it typically points to a catalytic converter issue, it can just as easily be generated by a variety of engine problems not directly related to the converter. Possible “non-converter related” P0420 causes: • Intake manifold leaks • Fuel injector leakage • Wrong spark plugs • Incorrect ignition timing • EGR problem • Oil or antifreeze entering exhaust • O2 sensor malfunction • Road damage to converter • RTV silicone contamination (re-use of improper volatile RTV) Avoid silicone and Tefon contamination. In addition to incompatible RTV, siliconebased products or Tefon sealants can also generate a P0420 and should not be used on any part of the exhaust system. They cannot operate at high exhaust temperatures and will out-gas and damage the O2 sensors. When it comes to service issues on today’s vehicles, the diffculty in correctly

Most, if not all, catalytic converter failures are caused by a problem or malfunction somewhere in the emission system ahead of the converter. So, it’s very important to determine what actually caused the converter to fail, so that the problem can be repaired and a recurrence can be prevented. Here are some troubleshooting suggestions: Method 1: Vacuum test Connect a vacuum gauge to the vacuum on the intake manifold, carburetor, or throttle body. Note the reading at idle. Then raise and hold engine speed at 3,000 rpm. The needle will drop when you frst open the throttle, but should then rise and level off. If the vacuum reading starts to drop, pressure may be backing up in the exhaust system indicating a blockage somewhere in the exhaust system. Method 2: Backpressure test Measure backpressure directly. If the vehicle’s engine has air injection, disconnect the check valve from the distribution manifold and connect a low pressure gauge. Or, remove the oxygen sensor and take your reading at its port in the manifold or head

pipe. A reading of more than 1.25 psi at idle or more than 3 psi at 2,000 rpm tells you there’s an exhaust restriction. Method 3: Temperature test In late model engines with fuel injection, the combustion is so effcient that the converter has little to process and the difference between the inlet and outlet temperatures may only be 50 degrees F at 2,500 rpm. This is a lot less than the old rule of thumb that says a good converter should show at least a 100 degrees F difference. At idle, the converter in many late-model vehicles may cool down so much that there’s almost no measurable difference between the front and back temperatures. So checking exhaust temperatures front and back of the converter at idle and 2,500 rpm may not be an accurate way to determine if the converter is working or not.

Watch out for contamination Silicone-based products or Tefon sealants should not be used on any part of the exhaust system. They are not designed to operate at high exhaust temperatures and will outgas, causing damage to O2 sensors. See page 20 for some examples of O2 sensor

contamination caused by the use of RTV silicone on exhaust manifold fanges and other components as well as Tefon-type sealants used on O2 sensors.

Fuel trim If you are trying to diagnose driveability issues but don’t have any trouble codes to chase, take a closer look at the engine’s fuel trim. When analyzed properly, it can be a valuable diagnostic tool, serving as a window to the heart of the fuel management system.

vehicle issues. That’s why fuel trims are so useful. They can provide an overall picture of what is causing the problem such as an intake manifold vacuum leak (positive fuel trim — lean) or a stuck open fuel injector (negative fuel trim — rich).

Short-term fuel trim

Short-term fuel trim (STFT1 and STFT2) is the computer’s immediate response to adjust the air/fuel ratio. In positive corrections, fuel is added to adjust for a lean condition, while negative corrections respond to a rich condition. STFT corrections represent Understanding fuel trim the current engine run cycle and react very A vehicle’s computer system uses fuel trim quickly to O2 sensor input. If you were to to help maintain the ideal air/fuel ratio create a large vacuum leak at idle by disconfor complete combustion (stoichiometry — necting the PCV hose, the computer would 14.7 parts air to one part fuel).

Fuel trims can compensate for other the next start/run cycle.

Long-term fuel trim Unlike STFT, long-term fuel trim (LTFT1 and LTFT2) is learned over time while in closed loop operation. It is stored in the KAM and also used for open loop fuel calculations (like start up and wide open throttle). LTFT is a wider adjustment and also works to keep STFT within specifcation.

Diagnosing with fuel trims Fuel trims can help you zero-in on the problem, especially when there are no other trouble codes present. Knowing whether an engine is running too rich or too lean will help narrow down your diagnosis. Fuel trims that differ greatly from one cylinder bank to the other will also point you in the right direction. Always evaluate fuel trims at idle and at 2,500 rpm. Running too rich — High negative fuel trim corrections can be caused by MAF sensor problems, high fuel pressure, leaking fuel pressure regulator diaphragm, faulty evaporative emissions components, leaking injectors, defective O2 sensors, exhaust leaks/pinholes before the O2 sensor, coolant temp sensor problems, and base engine issues such as low compression and incorrect camshaft timing. Running too lean — High positive fuel corrections can be traced to MAF and O2 sensor faults, vacuum leaks from intake gaskets/hoses, un-metered air (such as an intake snorkel leak), clogged or dirty fuel injectors, fuel delivery issues, and exhaust restrictions such as a clogged catalytic converter. Here’s a diagnostic tip: For a suspected vacuum leak, note the fuel trims at idle and increase engine speed to 2,500 rpm and hold. If the STFT immediately decreases and moves to acceptable levels and the LTFT slowly starts to come back down, you have a vacuum leak. After the repair, reset the KAM and start the engine. Monitor the fuel trims to make sure they are within the normal ranges. Achieving an accurate LTFT reading may require as much as 10 miles of driving.

Catalytic converter break-in That’s right — a replacement catalytic converter needs a proper “break-in” period, just like a new engine or a set of new brake pads. This will ensure that the cat will continue to work the way it is supposed to and deliver the required emissions reliability and long service life. If the converter is not warmed-up (broken-in) properly, the substrate inside could be adversely affected and eventually cause the converter to fail down the road. The problem typically occurs when a shop installs the converter and immediately returns the vehicle to the customer. The customer drives away and runs the car for a long distance or lets the vehicle idle for an extended period of time. Under these conditions, the matting, which is intended to secure the substrate, will not expand properly and hold it in place. Converter matting is made from a mineral called vermiculite, which is held together by a fber mat and an organic binder. This matting is wrapped around the converter’s ceramic brick (see art on page 20). The matting is installed in the converter in an unexpanded state. During the frst heat-up, the fber mat and binder burn off

and the matting actually gets looser before it expands to fll the converter cavity to hold the ceramic brick in place (see graph below). If that warm-up is not done properly, the brick can come loose and get damaged. That rattle you might hear inside the converter shell is a sure telltale sign for this problem.

Warm up the cat The best way to avoid this service issue and potential warranty problems is to include the warm-up period as a key part of your overall converter installation procedure. This heating cycle will allow for correct matting expansion.

Converter break-in tips • Start the engine but do not rev the engine. • Idle the engine and allow it to warm up slowly. • After fve minutes, increase the engine speed to 2,500 rpm. • Hold at 2,500 rpm for two minutes. • Allow the engine to cool down. • Road test to confrm correct installation. ●

are expensive, they cannot be returned, and on the late model vehicles they cannot be swapped without being reprogrammed or sometimes not swapped at all! The stakes are very high when diagnosing a module, but there is a way you can diagnose a module with 100% confdence. There are not that many steps, because diagnosing a module employs simple logic. Here are the steps to diagnose any module when you have a DTC:

ow long do most diagnostics take you? Maybe an hour? A diagnostic procedure that can be completed that quickly is usually pretty cut and dried, such as a bad sensor or vacuum leak. When diagnostics start taking longer and the problem seems to continue after we change common failure components, we start suspecting a bad module. 1. Check TSBs to see if there are any When a module arouses suspicion, you software updates, extended warranties for start to doubt yourself.

replace a module. (DO NOT SKIP THIS STEP! Follow Step 1 frst before wasting your time taking needless measurements or replacing any components.) 2. Diagnose and repair any bad sensors or actuators that may be responsible for the DTC. (This is very time consuming, but necessary.) 3. When all measurements and components are good, look for illogical PID data or vehicle conditions given the sensor feedback. You don’t need to be Socrates or Spock to understand logic. Logic is simple and absolutely necessary when diagnosing modules. Why? Because when the car does things that are the opposite of what you expect, it is only natural to become overwhelmed and want to start guessing. Don’t start guessing! Let yourself be informed by your diagnostics. On a vehicle, we must make our decisions based upon solid evidence that tests on a

vehicle will provide us. We’re going to cover our three step module diagnostic process using a case study so we can learn how to be confdent of how to diagnose modules.

2002 Jeep Liberty 3.7L with wrong fuel level reading We had a 2002 Jeep Liberty in our shop and the problem with the vehicle was that its fuel gauge went onto the empty indicator remarkably soon (see Figure 1). Also, the instrument cluster displays for the vehicle’s four-wheel-drive system worked backwards. For example, twowheel-drive was engaged when 4-HI was illuminated and vice versa. We had some decent information from the customer to work with. First, flling up the vehicle with gas right after the indicator hit “empty” resulted in taking only nine gallons of gas in an 18-gallon tank. Also, we knew that the fuel level sender unit was replaced. So, we know that there is defnitely a

problem and that it is not caused by a faulty fuel level sender unit. If itâ&#x20AC;&#x2122;s not the fuel level sender unit, what could it be? Immediately we conjured up the idea that there is an issue with the PCM or the instrument cluster. Why? Because what are the chances there are two separate issues causing a problem refected on the instrument cluster? Both are high risk propositions. How do we discern which one is the problem? 1. Check TSBs and Identifx. Chrysler had a recall for fuel pumps and Identifx told us what we already knew. Time to start testing. 2. Diagnose and repair any bad sensors or actuators. So, where do we begin with our diagnosis? First, we simply plugged in different scan tools, because not every scan

tool gave us both the fuel level PID as both a voltage and fuel level. The Launch X431 was a surprisingly good Euro-Asian tool, and following it up with the Snap-on Modis and the OTC Pegisys we found that they all agreed that the fuel level was supposedly 21%. We knew that this was not really the case. We got a little more information from the Modis, because it showed us that the fuel level sender unit voltage was 2.84 V (see Figure 2 on page 25). After looking up the specifcations, an empty fuel tank should have had 8.6 V while a full one should be 0.6 V. So, if we took the 2.84 V fuel level sender unit voltage as gospel truth, the fuel tank should have been at three-quarters. Yet, we should have known better than to make such an assumption. The fuel tank

was probably at about 50% because the customer informed us of the mileage he put on the vehicle since his last fll-up. When we start seeing all these numbers, it is easy to start getting confused. So, we decided to measure voltage at the fuel level sender unit’s signal wire to verify our scan readings. We knew the part was brand new from a previous attempt at repair, but you never know whether or not a part is defective. What we found only confused us more. We had 4.8 V leaving the sender unit. This corresponded with our belief that the tank was actually half full even though it was reading otherwise. After all, 4.8 V is about half of 8.9 V. But, where did the 2.84 V on the Modis come from? And, if the PCM thought it was receiving 2.84 V, why wasn’t the gauge at 75%? We verifed that we were getting 12 V to the sender unit and we found the sender unit’s signal wire at the PCM was 4.8 V. Being in denial that the PCM was to blame, we decided to make sure that the new fuel level sender unit was indeed operational. We did this by using the specifcations for ohms of resistance that the sensor would regularly have under different fuel level conditions and replicating it by placing resistors in place of the actual component. We looked at the ohms specifcation and found that the sender unit was supposed to have 5 ohms of resistance with a full tank and 270 ohms when empty. Here were our results on this Jeep Liberty:

• 20 ohm resistor: full tank • 30 ohm resistor: 7/8 of a tank • 45 ohm resistor: 3/4 of a tank • 62 ohm resistor: 1/2 of a tank • 77 ohm resistor: just below 1/2 a tank • 94 ohm resistor: 1/4 of a tank • 109 ohm resistor: 1/8 of a tank • 124 ohm resistor: tank at empty The following, though tedious, proved that at half a tank of gas as dictated by ohms of resistance the gauge will read empty. We saw it with our own eyes that we were able to predictably change the fuel level using this method. So, as long as our specifcations were right, the only thing to blame was the PCM itself. There was just one piece missing from the puzzle. Will the PCM fx the four-wheeldrive problem where it would show 2WD drive when it was in 4WD on the dashboard and vice versa? None of the scan tools we had showed a PID for the four-wheel-drive switch position, so we had to pull out the switch to see if the switch was OK before condemning the instrument cluster or any other component. Using the specifcations on Identifx, we found that the switch was faulty (refer to Figure 4 above). The PCM was not to blame at all, nor the instrument panel! The switch was broken, as its ohms for 2WD were fip-fopped with the resistance measured on 4WD-HI. Why did we go into detail about this? This vehicle had two legitimate problems: One was that the PCM was causing the wrong

fuel level and the other the bad switch was causing the cluster to show the wrong driving mode. It is easy to get fustered when cars do this, but just keep things logical and trust your testing results. 3. Look for illogical PID data. So, our testing proved two things. First, the 4WD issue was not related. Second, the PCM was incorrectly interpreting the signal voltage from the fuel level sending unit. We could have diagnosed this vehicle a lot quicker by simply just looking for illogical PID data. Hereâ&#x20AC;&#x2122;s what stuck out to us: How can the fuel level sender unit voltage PID suggest the tank is at least half a tank, but the fuel level PID as a percentage thought the tank was nearly empty? The Modis specifcally had two contradicting values, so the only possible cause would be a bad PCM. Why? The fuel level PID is simply an interpretation of the fuel level sender unit voltage PID. The fuel level sender unit is not responsible for interpreting its voltage signal. It simply just sends it out to the PCM. So, the only thing that can be blamed for the wrong fuel level PID would have been the PCM. If it was a bad instrument panel, it would just have the wrong fuel level displayed

instead of contradictory parameter IDs. Bad wiring from the fuel level sender unit might send incorrect voltage to the PCM, but it could not make the PCM make a false interpretation of that voltage. We did not even have to modify the signal voltage using resistors to prove this or even check voltage at the actual sending unit! All we needed was a scan tool. Why? Even if the PCM said one voltage was coming from the sender unit and our meter gave us another, only a PCM issue can make PIDs that contradict one another. All the bad wiring in the world cannot make a module think voltage is one thing and then interpret that voltage to be something else that would make no sense. A new PCM fxed the fuel level issue. See how by (1) checking TSBs (at least we found out that we had to do some testing), (2) diagnosing any non-module components (such as the 4WD issue and the sender unit), and (3) looking at illogical PID data we were able to logically condemn the module and feel good about it, too? Next time we are going to take this approach and apply it to a BMW X5 air suspension system just to prove no matter how complicated the system, we can use the same simple logic to diagnose the vehicle. â&#x2014;?

Tech tip Causes for repeat failures of fuel pumps TURN DOWN THE HEAT Several years ago, Identifx published an article titled “Fuel Pump Blues,” which dealt with repeat fuel pump failures. A poor ground caused excessive heat buildup and was responsible for this repeat problem. The article concerned a ground problem behind the left rear wheel well on a 1987 Chevrolet Celebrity with a 2.5 liter engine. The current draw on this circuit was 2 to 4 amps with the pump achieving 9 to 13 psi of operating pressure. Today’s fuel pumps are designed to create full operating pressures of 60 psi to 66 psi. Obviously, the current draw is much higher. Most high-pressure systems, such as the one found in a 2000 Chevrolet Express van with a 5.7 liter engine, will have a current draw of 9 to 11 amps. Consequently, the potential for building excessive heat caused by high resistance has greatly increased. The frst area of concern for excessive heat is the actual fuel pump itself. When the fuel tank is continually run with a very low fuel level, the fuel will no longer have the ability to keep the pump cool. Then there is the problem of poor connections at the fuel tank sending unit resulting in excessive heat, which will eventually damage or melt the connector and reduce the life of the fuel pump. What is the best course of action when multiple fuel pumps are installed and there are no visible problems at the sending unit connector? In this case, the place to look is the fuel pump relay. This particular vehicle has no oil pressure switch backing up the fuel pump relay. Because of this, all of the current to the fuel pump is going through the fuel pump relay. Should there be a problem with the fuel pump relay or the underhood fuse relay

center, the current fow of the circuit will drop causing the pump to work harder to produce the same amount of pressure. This will result in repeat fuel pump failures. What are some of the common problems found at the relay and/or the underhood fuse relay center? 1. Poor terminal contact between the fuse block terminals and the relay. This will create excessive heat and eventually damage the underhood fuse relay center by causing the plastic housing to melt. Additionally, today’s terminals are made using less material. This decrease in maternal may cause the terminals of the relay center to deform, resulting in poor terminal contact. 2. Possible problem with the 12-volt supply to the relay from the powertrain control module (PCM). In several cases, the PCM was unable to supply full voltage to the relay causing the contacts of the relay to make poor contact. This created high resistance across the contacts of the relay which in turn created a build-up of heat. 3. Like the problem with the power feed from the PCM, a ground problem for the fuel pump relay also will cause the contacts of the relay to make a poor connection. Again, poor contact will create higher resistance and create excessive heat. When servicing a fuel pump, be sure to check the connections at the fuel tank sending unit and the underhood fuse relay center. Verify that the ground for the coil side of the relay is in excellent condition and that the computer is able to supply full system voltage to energize the relay. These tips can save the aggravation of repeat fuel pump failure. ● Information for this Tech Tip is courtesy of Identifx Inc. See www.identifx.com.

LS cam change Changing a camshaft in the GM LS engine. The LS is a different animal as compared to the earlier small block Chevy By Mike Mavrigian

ervicing a camshaft in any overheadvalve engine requires a degree of disassembly, but in the case of GM’s LS-series of engines, the task is a bit less tedious, since there is no need to remove the intake manifold, upper engine cover or lifters. Here we’ll explain the process. 1. Remove both valve covers. 2. Remove all rocker arms. 3. Remove the following components: • Water pump • Crankshaft pulley • Oil flter • Oil pan • Front engine cover (timing cover) • Oil pickup tube/screen assembly • Oil pump • Oil pump drive gear (slides off of the crank snout) 4. Rotate the crankshaft two full turns (360 degrees), and position the crank gear and cam sprocket dots (cam gear dot at 6-o’clock and crank gear dot at 12-o’clock). Once positioned, DO NOT rotate the crankshaft at any time during the process. (By rotating the crank two full turns, this causes the camshaft lobes to push the lifters up into the plastic lifter buckets. With no valve spring pressure, since the rockers have been removed, the lifters will “snug” into the lifter buckets, holding the lifters up and away from the camshaft, allowing a clear path for camshaft removal without the need to remove the lifters. Note that in order to remove the lifters, the cylinder heads must be removed. This feature (lifters secured in

When servicing the camshaft on an LS engine, there’s no need to remove the intake manifold or top engine cover, but you will need to disassemble the front of the engine and remove the oil pan.

As this example of a bare LS block shows, there’s no access to the lifters at the top valley. The lifters are located in the upper deck areas of the block and are held captive by the cylinder head. When removing or installing a cam, there’s no need to remove the heads either.

34 | July/August 2013

A dedicated camshaft “handle” will provide a secure grip and added leverage to remove or install the camshaft. This Trick Flow camshaft grip features a somewhat universal bolt pattern and will accept an LS camshaft.

This view shows the timing setup (with pulley, water pump, front cover and oil pump removed). Depending on the version of the oil pump drive gear, this might incorporate the crank gear or it may be a separate gear.

After rotating the crankshaft two full turns with the rocker arms removed, the cam lobes have pushed the roller lifters up into their guide buckets, which provides a clear unobstructed path for cam removal or installation. As a safety precaution, once the camshaft retainer plate has been removed, insert a pair of clean metal rods through the two lifter oil galleys. If one or more lifters accidentally fall out of the “locked” position, the rods will prevent the lifter from dropping into the path of the cam. Leave the rods in place until the new camshaft has been installed.

The cam grip registers to the camshaft nose dowel pin and is secured with one or more bolts (the grip will accommodate a single-bolt or three-bolt style camshaft).

the buckets) avoids the need to remove the heads). There is no need to remove the intake manifold or the upper engine cover plate. There is no access to the lifters at the top valley, and there’s no need to remove the lifters anyway. 5. Remove the camshaft sprocket and timing chain. 6. Remove the camshaft retaining plate. 7. The camshaft is now ready for extraction. However, even though the lifters

35 | July/August 2013

are being held out of the way in their respective buckets, there is still a chance for one or more lifters to accidentally fall out, which would then require cylinder head removal in order to retrieve the lifter(s). In order to avoid this potential problem, carefully insert a pair of 1/4-inch or 5/16-inch-diameter metal rods into the lifter oil galley passages (one rod into the oil galley on each side of the camshaft bore). Use rods that are about 28 inches long (or longer). This serves as a backup. In case a lifter tries to fall, the rod will stop it and keep the lifter engaged in its bucket’s fat registers (keeping the lifter in proper alignment). Leave these rods in place until the new camshaft has been installed. 8. Using a suitable camshaft removal/ installation tool/handle, carefully remove the camshaft and avoid dragging the lobes across the cam bearings. Again, proceed slowly and carefully. Scraping a cam bearing will result in a severe oil pressure drop and will require bearing replacement. 9. Before installing the replacement camshaft, coat all cam journals with either clean engine oil or an engine assembly lube. Coat all cam lobes either with clean engine oil or a high-pressure lubricant designed for camshaft breakin. Even though the LS engines feature roller lifters, it never hurts to use a quality high-pressure lubricant. 10. Remove the two temporary metal rods from the lifter oil galleys. 11. By hand, push each pushrod fully downward in order to dislodge the lifters from their buckets, allowing each lifter to contact its cam lobe. 12. Install a NEW camshaft retainer plate. The imprinted sealant on the rear of the plate tends to harden over time, so it’s recommended to always use a new retainer plate. Depending on the version of the engine, the retainer plate bolts may feature a hex head or a Torx head. Hex head bolts are tightened to 18 ft.-lbs., while Torx bolts are tightened

Before installing the fresh camshaft, clean thoroughly to remove any protective flm or grease that may have been applied at the factory, and coat journals and lobes liberally with a quality camshaft or engine assembly lubricant. Even though a roller style camshaft doesn’t face the same potential harm as a fat-tappet cam during break-in, a high pressure cam lube still isn’t a bad idea. Unlike a fat-tappet cam, a roller cam/roller lifter setup really doesn’t face a “break-in” issue.

Always install a new camshaft retainer plate on any LS service. The printed sealing bead may have hardened over time. An LS gasket set usually includes a new retainer plate.

With the new camshaft in place (and with the temporary metal rods removed), install the retainer plate and tighten the fasteners to specifcation. If the retainer plate bolts feature hex heads, tighten to 18 ft.-lbs. If there are Torx heads, tighten to 11 ft.-lbs. Apply thread locker beforehand.

Install the camshaft sprocket and timing chain, aligning the timing dots. Tighten the cam sprocket bolts to 18 ft.lbs. (with thread locker). 14. Install the rocker arms, tightening all rocker arm bolts to 22 ft.-lbs. NOTE: The intake rocker arm bolt holes in the cylinder heads are open to the intake runners. Apply a thread sealer to all INTAKE rocker arm bolts before installation. 15. Install the oil pump drive gear onto the crank snout (depending on the version, this may incorporate the crank gear, in which case you’ve already installed it during the timing chain installation, or it may be a separate radius-toothed gear that slides on after the crank gear). 16. Install the oil pump to the block (aligning the pump’s foating driven gear to engage onto the drive gear). Install the

The LS roller lifters are guided by plastic “lifter buckets.” These buckets feature a female two-sided fat design that guides the lifters and keeps them in plane relative to the cam lobes. With the rockers removed and with the crank rotated 360 degrees, the lifters are fully pushed up inside the buckets.

Once the new camshaft has been installed, simply push each pushrod down to allow the lifter to pop out of its secured position, allowing the lifter roller to contact the cam lobe.

NEVER try to force any balancer or pulley into place by striking it with a hammer or other impact tool. Refer to the information on page 46 regarding crankshaft pulley bolts. 21. Once the crank pulley has been installed, install the water pump using two new gaskets. These are aluminum cores with imprinted sealing beads. Even though the old gaskets may appear to be usable, donâ&#x20AC;&#x2122;t risk it. Install new gaskets. Tighten the water pump bolts in two steps: frst tighten all bolts at 11 ft.-lbs., and then at 22 ft.-lbs.,

Crankshaft pulley bolt

The LS crankshaft snouts feature a 16 mm x 2.0 thread size. When installing the crank pulley, you have two choices in terms of the pulley bolt: the OE TTY (torque to yield) bolt, or the ARP bolt. My recommendation is to use the ARP bolt. When using an OE bolt, you must follow a more tedious process, and you’ll need two of these bolts. First (after making sure that the crank female threads are clean), position the pulley onto the crank snout.

crankshaft does NOT rotate during the angle tightening. The ARP bolt is a high-quality bolt with a high tensile strength, and does not require a torque-plus-angle approach. Simply lube the bolt threads and the underside of the bolt head with ARP’s engine assembly lube, slip on the provided hardened washer and torque to a fnal value of 235 ft.lbs. (You must use this moly lube in order to achieve the desired torque value. Do not use engine oil.) Granted, the ARP bolt is more expensive than the OE bolt, but it’s more dependable, much easier to install (no torque/angle process to mess with), and does not require a “donor” bolt for initial tightening. This bolt can be reused during future service, unlike the OE bolt. NOTE: All wet-sump LS engines (LS1, LS6, LS2, LQ4, LQ9, etc.) require a 16 mm x 2.0 bolt that features a shank length of 4.325 inches. All dry sump LS engines (LS7, etc.) require a longer 5.225-inch bolt to accommodate the pump drive. If purchasing the ARP bolt, the part number for the wet sump engines is 2342503. The dry sump engines require P/N 234-2504.

There’s more to a flter than meets the eye. The type of media substantially affects performance.

Clearing the air about flters The ins and outs of the components that keep vehicles running clean Compiled by Bob Weber

The following article was written by Dan Pike, group executive, Filter Manufacturers Council (FMC) and vice president, membership and members services, Automotive Aftermarket Suppliers Association.

t’s time to clear the air about flters — those automotive components which keep your customers’ vehicles running clean. Here is a brief overview of motor vehicle

Filters: It’s what’s inside that counts Any discussion of motor vehicle flters begins with flter media — the material inside the flter which captures dirt and foreign particles. Filter manufacturers use many different types of media for various fuids and environmental extremes. The most common used flter media are cellulose-based and glass.

50 | July/August 2013

Circle 119 on Reader Service Card

Cellulose media is manufactured with fbers of various sizes. On the top layer of the media, the fbers are fuffed up, rather than compacted down. When fuid and contaminants pass through the media, many particles collect on the fuffy fbers on the surface and don’t travel further into the flter. Glass media was developed to be utilized in hydraulic systems because it has low fow restriction at high fltration effciencies. These low-fow resistance properties are benefcial in hydraulics where cold oil is being forced through the media and when fltration in the 3 to 5 micron range is desired. Glass media has a drawback regarding capacity. Typically, glass media has the same pore size and same fber diameter through the entire sheet. The media can be manufactured to be very effcient, but then it is so tight that it has very little life or capacity. Synthetic media is making inroads in replacement flters. In most lube, fuel and air flter applications, cellulose media remains the better choice. As with glass, the reason largely relates to capacity, or

flter life. A brief description of the fltering process illustrates this. The process of fuids and contaminants collecting on the fuffy fbers of cellulose flter’s surface is called “adsorption.” The particles adhere to the surface fbers and don’t travel farther into the flter. The more adsorption a media applies, the more small particles can be separated before they reach the small pore spaces on the screen side of the media. This keeps these small particles from plugging the media. Cellulose media typically is thicker than synthetic. The thicker the media is, the more time the particles spend traveling through it. Each time the fuid changes direction around a fber, the momentum keeps particles traveling in the same direction they were going and they are driven into the fbers. This particle separation is called “impingement.” As with adsorption, the more impingement that a media applies, the more particles are separated without plugging the tight pore space on the screen side. Synthetic media does separate some particles with adsorption and impingement, but the smooth fbers can’t hold the particles in

Knock-off products that may not meet OEM standards infest the global marketplace, and oil flters are no exception. It’s obvious the flter on the left is a “fake,” constructed with less media and of lower quality, compared to the “original” on the right.

place. Often they are washed off with the fuid traveling through the media. Synthetic media primarily uses the particle separation technique called “direct interception.” Direct interception is simply separating particles by passing the fuid through pore spaces that are small enough to catch them. However, once all pores are flled with the contaminant, the flter is plugged and its life is over. Because cellulose media is better at adsorption and impingement, it can remove more contaminants than glass or synthetic media without plugging pore spaces. Can a synthetic media be created with the benefts of cellulose media? This remains to be seen. For now, both cellulose-based media and glass media have a place in today’s flter market.

Today’s diesels feature DEF for NOx reduction. If you service diesels, you need a method of checking DEF quality. A refractometer designed specifcally for DEF is an essential tool.

OTC DEF refractometer Checking a customer’s diesel exhaust fuid concentration By Mike Mavrigian

tarting with 2010 models, all dieselpowered vehicles in the U.S. feature a DEF system (diesel exhaust fuid). The purpose of the DEF is to reduce NOx emissions utilizing a management-controlled mist injection of DEF into the exhaust stream. DEF is a mixture of purifed urea and purifed water (refer to the May/June 2013 issue of Auto Service Professional for details regarding DEF systems). Contaminated or improper-mix DEF can cause operational problems in these systems.

In order to verify the purity of a customer’s DEF supply, a simple method involves the use of a refractometer. While this type of tool has been used for decades for testing engine coolant, OTC now offers a refractometer specifcally designed for the testing of DEF, available under part number 5025. OTC’s 5025 DEF Refractometer is a portable, precision optical instrument designed to measure DEF concentration. When a liquid sample is placed on the tool’s prism, the light passing through the sample is bent (refraction). The more

concentrated the liquid, the more the light will bend. The refractometer features a reticle scale that is viewed by looking into the magnifed eyepiece. With no liquid on the prism, the eyepiece view will reveal a light blue background with the graduated scale. The background is an even shade of blue from top to bottom. Once a drop of sample liquid is placed on the prism, a darker “shadow” will appear at the top of the scale. The point at which the bottom edge of the shadow hits the scale indicates the condition of the DEF sample.

Operating instructions The refractometer must frst be set up in terms of eyepiece focus and calibration.

5. Close the cover and press it lightly. 6. View the scale and note where the bottom of the shadow line intersects with the percentage scale. The ideal, or target reading is 32.5%. If under, more DEF concentration is needed. If over, the urea concentration is too high. In reality, most DEF purchases will consist of premixed containers. If the concentration level is incorrect, either the DEF was of low quality or the tank has become contaminated. The DEF tank should be drained and reflled, only with a known high quality DEF. NOTE: To ensure consistent readings, the refractometer should be zeroed with pure water and DEF-tested at the same ambient temperature.

After popping off the rubber cap, use the supplied screwdriver to adjust the scale for zero calibration to pure water.

The OTC 5025 kit includes: • A plastic storage case with form-cut foam. • Refractometer (range of 15% to 40%; resolution of 0.5%). • Soft cloth. • Long-neck dropper. • Screw driver (for calibration adjustment). • Small plastic bottle for pure water. • Pointer.

that the DEF I purchased does indeed have the proper concentration as required). Granted, high-tech digital DEF meters are also available that may be quicker to use, but they cost several hundreds of dollars and require batteries. The simple OTC DEF refractometer needs no batteries, and costs a bit over $100 or so (depending on where you buy it, of course). NOTE: As simple as it may appear, a quality refractometer is a precision instrument and should be treated accordingly. Once your check has been completed, clean and dry the prism, and pack it away in the storage case, along with the dropper, water bottle and cloth. If the tool breaks or malfunctions, it will only be due to mishandling or improper storage. â&#x2014;?

SQUEAKY ESCAPE Some 2001-2011 Ford Escape and 20052011 Mariner vehicles may exhibit an underbody squeak or creak noise when accelerating from a stop or when braking to a stop.

If the noise can be isolated to one or both of these specifc locations, suspect that the subframe locating pins are contacting the locating holes of the vehicle body. Loosen the two front subframe nuts and the two front subframe attachment bolts. Reposition the subframe to center the locating pins so that there is no longer contact with any edge of the locating hole (see Figure 2). NOTE: Do not allow the front subframe rear bolts to come out of the lower control arm bushing. Tighten the front subframe nuts (refer to the workshop manual, Section 502-00). ALSO NOTE: The pins are more likely to contact the rearward side of the holes. Therefore, the subframe assembly will most likely need to be moved forward in the vehicle. When installing the front subframe rear bolts, ensure that both front subframe rear bolts are fully engaged in their nuts before tightening to specifcation.
