PRECAUTIONS PRECAUTIONS Description
PFP:00001
GI NAS00001
Observe the following precautions to ensure safe and proper servicing. These precautions are not described in each individual section.
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”
B
NAS00002
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the SRS and SB section of this Service Manual. WARNING: ● To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. ● Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see the SRS section. ● Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.
Precautions for Battery Service

General Precautions ●
NAS00005
Do not operate the engine for an extended period of time without proper exhaust ventilation. Keep the work area well ventilated and free of any flammable materials. Special care should be taken when handling any flammable or poisonous materials, such as gasoline, refrigerant gas, etc. When working in a pit or other enclosed area, be sure to properly ventilate the area before working with hazardous materials. Do not smoke while working on the vehicle. SGI285
Revision: 2006 November
GI-3
2007 350Z
PRECAUTIONS ●
●
Before jacking up the vehicle, apply wheel chocks or other tire blocks to the wheels to prevent the vehicle from moving. After jacking up the vehicle, support the vehicle weight with safety stands at the points designated for proper lifting before working on the vehicle. These operations should be done on a level surface. When removing a heavy component such as the engine or transaxle/transmission, be careful not to lose your balance and drop them. Also, do not allow them to strike adjacent parts, especially the brake tubes and master cylinder. SGI231
●
●
●
Before starting repairs which do not require battery power: Turn off ignition switch. Disconnect the negative battery terminal. If the battery terminals are disconnected, recorded memory of radio and each control unit is erased. Battery posts, terminals and related accessories contain lead and lead compounds. Wash hands after handling.

To prevent serious burns: Avoid contact with hot metal parts. Do not remove the radiator cap when the engine is hot. Dispose of or recycle drained oil or the solvent used for cleaning parts in an appropriate manner. Do not attempt to top off the fuel tank after the fuel pump nozzle shuts off automatically. Continued refueling may cause fuel overflow, resulting in fuel spray and possibly a fire. Clean all disassembled parts in the designated liquid or solvent SGI233 prior to inspection or assembly. Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new ones. Replace inner and outer races of tapered roller bearings and needle bearings as a set. Arrange the disassembled parts in accordance with their assembled locations and sequence. Do not touch the terminals of electrical components which use microcomputers (such as ECM). Static electricity may damage internal electronic components. After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection. Use only the fluids and lubricants specified in this manual. Use approved bonding agent, sealants or their equivalents when required. Use hand tools, power tools (disassembly only) and recommended special tools where specified for safe and efficient service repairs. When repairing the fuel, oil, water, vacuum or exhaust systems, check all affected lines for leaks.

WARNING: To prevent ECM from storing the diagnostic trouble codes, do not carelessly disconnect the harness connectors which are related to the engine control system and TCM (transmission control module) system. The connectors should be disconnected only when working according to the WORK FLOW of TROUBLE DIAGNOSES in EC and AT sections.
E
Precautions for Three Way Catalyst
F
NAS00006
If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To prevent this, follow the instructions. ● Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst. ● When checking for ignition spark or measuring engine compression, make tests quickly and only when necessary. ● Do not run engine when the fuel tank level is low, otherwise the engine may misfire, causing damage to the catalyst. Do not place the vehicle on flammable material. Keep flammable material off the exhaust pipe and the three way catalyst.
Precautions for Fuel (Unleaded Premium Gasoline Required)
G
H
I
NAS0005P
Use unleaded premium gasoline with an octane rating of at least 91 AKI (Anti-Knock Index) number (Research octane number 96).
J
If unleaded premium gasoline is not available, unleaded regular gasoline with an octane rating of at least 87 AKI number (Research octane number 91) can be used, but only under the following precautions: ● have the fuel tank filled only partially with unleaded regular gasoline, and fill up with unleaded premium gasoline as soon as possible. ● avoid full throttle driving and abrupt acceleration. However, for maximum vehicle performance, the use of unleaded premium gasoline is recommended.
K
CAUTION: Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Do not use E-85 fuel (85% fuel ethanol, 15% unleaded gasoline) unless the vehicle is specifically designed for E-85 fuel (i.e. Flexible Fuel Vehicle - FFV models). Using a fuel other than that specified could adversely affect the emission control devices and systems, and could also affect the warranty coverage validity.

E
HEALTH PROTECTION PRECAUTIONS ● ● ● ● ●
● ● ●
● ● ● ●
Avoid prolonged and repeated contact with oils, particularly used engine oils. Wear protective clothing, including impervious gloves where practicable. Do not put oily rags in pockets. Avoid contaminating clothes, particularly underpants, with oil. Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regularly. First aid treatment should be obtained immediately for open cuts and wounds. Use barrier creams, applying them before each work period, to help the removal of oil from the skin. Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Preparations containing lanolin replace the natural skin oils which have been removed. Do not use gasoline, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin. If skin disorders develop, obtain medical advice without delay. Where practical, degrease components prior to handling. Where there is a risk of eye contact, eye protection should be worn, for example, chemical goggles or face shields; in addition an eye wash facility should be provided.

HOW TO PROBE CONNECTORS Connector damage and an intermittent connection can result from improperly probing of the connector during circuit checks. The probe of a digital multimeter (DMM) may not correctly fit the connector cavity. To correctly probe the connector, follow the procedures below using a “T” pin. For the best contact grasp the “T” pin using an alligator clip.
Probing from Harness Side Standard type (not waterproof type) connector should be probed from harness side with “T” pin. ● If the connector has a rear cover such as a ECM connector, remove the rear cover before probing the terminal. ● Do not probe waterproof connector from harness side. Damage to the seal between wire and connector may result.
SGI841
Probing from Terminal Side FEMALE TERMINAL ● There is a small notch above each female terminal. Probe each terminal with the “T” pin through the notch. Do not insert any object other than the same type male terminal into female terminal.

INCIDENT SIMULATION TESTS Introduction Sometimes the symptom is not present when the vehicle is brought in for service. If possible, re-create the conditions present at the time of the incident. Doing so may help avoid a No Trouble Found Diagnosis. The following section illustrates ways to simulate the conditions/environment under which the owner experiences an electrical incident. The section is broken into the six following topics: ● Vehicle vibration ● Heat sensitive Revision: 2006 November

SERVICE INFORMATION FOR ELECTRICAL INCIDENT Freezing Water intrusion ● Electrical load ● Cold or hot start up Get a thorough description of the incident from the customer. It is important for simulating the conditions of the problem. ● ●
Vehicle Vibration The problem may occur or become worse while driving on a rough road or when engine is vibrating (idle with A/C on). In such a case, you will want to check for a vibration related condition. Refer to the following illustration. CONNECTORS & HARNESS Determine which connectors and wiring harness would affect the electrical system you are inspecting. Gently shake each connector and harness while monitoring the system for the incident you are trying to duplicate. This test may indicate a loose or poor electrical connection. HINT Connectors can be exposed to moisture. It is possible to get a thin film of corrosion on the connector terminals. A visual inspection may not reveal this without disconnecting the connector. If the problem occurs intermittently, perhaps the problem is caused by corrosion. It is a good idea to disconnect, inspect and clean the terminals on related connectors in the system. SENSORS & RELAYS Gently apply a slight vibration to sensors and relays in the system you are inspecting. This test may indicate a loose or poorly mounted sensor or relay.
SGI839
ENGINE COMPARTMENT There are several reasons a vehicle or engine vibration could cause an electrical complaint. Some of the things to check for are: ● Connectors not fully seated. ● Wiring harness not long enough and is being stressed due to engine vibrations or rocking. ● Wires laying across brackets or moving components. ● Loose, dirty or corroded ground wires. ● Wires routed too close to hot components. To inspect components under the hood, start by verifying the integrity of ground connections. (Refer to Ground Inspection described later.) First check that the system is properly grounded. Then check for loose connection by gently shaking the wiring or components as previously explained. Using the wiring diagrams inspect the wiring for continuity. BEHIND THE INSTRUMENT PANEL An improperly routed or improperly clamped harness can become pinched during accessory installation. Vehicle vibration can aggravate a harness which is routed along a bracket or near a screw.
Revision: 2006 November

2007 350Z
SERVICE INFORMATION FOR ELECTRICAL INCIDENT UNDER SEATING AREAS An unclamped or loose harness can cause wiring to be pinched by seat components (such as slide guides) GI during vehicle vibration. If the wiring runs under seating areas, inspect wire routing for possible damage or pinching.
Heat Sensitive
B
The customer's concern may occur during hot weather or after car has sat for a short time. In such cases you will want to check for a heat sensitive condition. To determine if an electrical component is heat sensitive, heat the component with a heat gun or equivalent. Do not heat components above 60°C (140°F). If incident occurs while heating the unit, either replace or properly insulate the component.
C
D
E SGI842
Freezing The customer may indicate the incident goes away after the car warms up (winter time). The cause could be related to water freezing somewhere in the wiring/electrical system. There are two methods to check for this. The first is to arrange for the owner to leave his car overnight. Make sure it will get cold enough to demonstrate his complaint. Leave the car parked outside overnight. In the morning, do a quick and thorough diagnosis of those electrical components which could be affected. The second method is to put the suspect component into a freezer long enough for any water to freeze. Reinstall the part into the car and check for the reoccurrence of the incident. If it occurs, repair or replace the component.

I SGI843
Water Intrusion
J
The incident may occur only during high humidity or in rainy/snowy weather. In such cases the incident could be caused by water intrusion on an electrical part. This can be simulated by soaking the car or running it through a car wash. Do not spray water directly on any electrical components.

SERVICE INFORMATION FOR ELECTRICAL INCIDENT Cold or Hot Start Up On some occasions an electrical incident may occur only when the car is started cold, or it may occur when the car is restarted hot shortly after being turned off. In these cases you may have to keep the car overnight to make a proper diagnosis.
CIRCUIT INSPECTION Introduction In general, testing electrical circuits is an easy task if it is approached in a logical and organized method. Before beginning it is important to have all available information on the system to be tested. Also, get a thorough understanding of system operation. Then you will be able to use the appropriate equipment and follow the correct test procedure. You may have to simulate vehicle vibrations while testing electrical components. Gently shake the wiring harness or electrical component to do this. OPEN
A circuit is open when there is no continuity through a section of the circuit. There are two types of shorts.
SHORT
●
SHORT CIRCUIT
When a circuit contacts another circuit and causes the normal resistance to change.
●
SHORT TO GROUND
When a circuit contacts a ground source and grounds the circuit.
NOTE: Refer to “How to Check Terminal” to probe or check terminal.
Testing for “Opens” in the Circuit Before you begin to diagnose and test the system, you should rough sketch a schematic of the system. This will help you to logically walk through the diagnosis process. Drawing the sketch will also reinforce your working knowledge of the system.
SGI846-A
CONTINUITY CHECK METHOD The continuity check is used to find an open in the circuit. The digital multimeter (DMM) set on the resistance function will indicate an open circuit as over limit (no beep tone or no ohms symbol). Make sure to always start with the DMM at the highest resistance level. To help in understanding the diagnosis of open circuits, please refer to the previous schematic. ● Disconnect the battery negative cable. ● Start at one end of the circuit and work your way to the other end. (At the fuse block in this example) ● Connect one probe of the DMM to the fuse block terminal on the load side. ● Connect the other probe to the fuse block (power) side of SW1. Little or no resistance will indicate that portion of the circuit has good continuity. If there were an open in the circuit, the DMM would indicate an over limit or infinite resistance condition. (point A) ● Connect the probes between SW1 and the relay. Little or no resistance will indicate that portion of the circuit has good continuity. If there were an open in the circuit, the DMM would indicate an over limit or infinite resistance condition. (point B) ● Connect the probes between the relay and the solenoid. Little or no resistance will indicate that portion of the circuit has good continuity. If there were an open in the circuit, the DMM would indicate an over limit or infinite resistance condition. (point C) Any circuit can be diagnosed using the approach in the previous example.

SERVICE INFORMATION FOR ELECTRICAL INCIDENT VOLTAGE CHECK METHOD To help in understanding the diagnosis of open circuits please refer to the previous schematic. GI In any powered circuit, an open can be found by methodically checking the system for the presence of voltage. This is done by switching the DMM to the voltage function. ● Connect one probe of the DMM to a known good ground. B ● Begin probing at one end of the circuit and work your way to the other end. ● With SW1 open, probe at SW1 to check for voltage. voltage; open is further down the circuit than SW1. C no voltage; open is between fuse block and SW1 (point A). ● Close SW1 and probe at relay. voltage; open is further down the circuit than the relay. D no voltage; open is between SW1 and relay (point B). ● Close the relay and probe at the solenoid. voltage; open is further down the circuit than the solenoid. E no voltage; open is between relay and solenoid (point C). Any powered circuit can be diagnosed using the approach in the previous example.

Ground Inspection Ground connections are very important to the proper operation of electrical and electronic circuits. Ground connections are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can become an unwanted resistance. This unwanted resistance can change the way a circuit works. Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drastically affect an electronically controlled circuit. A poor or corroded ground can easily affect the circuit. Even when the ground connection looks clean, there can be a thin film of rust on the surface. When inspecting a ground connection follow these rules: ● Remove the ground bolt or screw. ● Inspect all mating surfaces for tarnish, dirt, rust, etc. ● Clean as required to assure good contact. ● Reinstall bolt or screw securely. ● Inspect for “add-on” accessories which may be interfering with the ground circuit. ● If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the wires are clean, securely fastened and providing a good ground path. If multiple wires are cased in one eyelet make sure no ground wires have excess wire insulation. For detailed ground distribution information, refer to “Ground Distribution” in PG section.
SGI853
Voltage Drop Tests Voltage drop tests are often used to find components or circuits which have excessive resistance. A voltage drop in a circuit is caused by a resistance when the circuit is in operation. Check the wire in the illustration. When measuring resistance with DMM, contact by a single strand of wire will give reading of 0 ohms. This would indicate a good circuit. When the circuit operates, this single strand of wire is not able to carry the current. The single strand will have a high resistance to the current. This will be picked up as a slight voltage drop. Unwanted resistance can be caused by many situations as follows: ● Undersized wiring (single strand example) ● Corrosion on switch contacts ● Loose wire connections or splices. Revision: 2006 November
GI-32
2007 350Z
SERVICE INFORMATION FOR ELECTRICAL INCIDENT If repairs are needed always use wire that is of the same or larger gauge. GI
MEASURING VOLTAGE DROP — ACCUMULATED METHOD ● Connect the DMM across the connector or part of the circuit you want to check. The positive lead of the DMM should be closer to power and the negative lead closer to ground. ● Operate the circuit. ● The DMM will indicate how many volts are being used to “push” current through that part of the circuit. Note in the illustration that there is an excessive 4.1 volt drop between the battery and the bulb.

H
SGI974
MEASURING VOLTAGE DROP — STEP-BY-STEP The step-by-step method is most useful for isolating excessive drops in low voltage systems (such as those in “Computer Controlled Systems”). Circuits in the “Computer Controlled System” operate on very low amperage. The (Computer Controlled) system operations can be adversely affected by any variation in resistance in the system. Such resistance variation may be caused by poor connection, improper installation, improper wire gauge or corrosion. The step by step voltage drop test can identify a component or wire with too much resistance.

TOW TRUCK TOWING TOW TRUCK TOWING Tow Truck Towing
PFP:00000 NAS0000Y
CAUTION: ●
All applicable state or Provincial (in Canada) laws and local laws regarding the towing operation must be obeyed. ● It is necessary to use proper towing equipment to avoid possible damage to the vehicle during towing operation. Towing is in accordance with Towing Procedure Manual at dealer. ● Always attach safety chains before towing. ● When towing, make sure that the transmission, steering system and power train are in good order. If any unit is damaged, dollies must be used. NISSAN recommends that the vehicle be towed with the driving (rear) wheels off the ground as illustrated. CAUTION: ● Never tow an automatic transmission model with the rear wheels or four wheels on the ground (forward or backward). This may cause serious and expensive damage to the transmission. ● When towing with the front wheels on the ground (if you do not use towing dollies), turn the ignition key to the OFF position, and secure the steering wheel in the straightahead position with a rope or similar device. Never place the ignition key in the LOCK position. This will result in damage to the steering lock mechanism. ● When towing a manual transmission model with the rear wheels on the ground (if you do not use towing dollies), release the parking brake and move the shift lever to the N (Neutral) position.

FRONT After removing the front licence plate (if so equipped), 1 Remove the recovery hook cover from the bumper. 2 Securely install the recovery hook stored with jacking tools. Make sure that the hook is properly secured in the stored place after use. WARNING: ● Stand clear of a stuck vehicle. ● Do not spin your tires at high speed. This could cause them to explode and result in serious injury. Parts of your vehicle could also overheat and be damaged.
B
C
D PAIA0064E
CAUTION: ● Tow chains or cables must be attached only to the vehicle recovery hooks or main structural members of the vehicle. Otherwise, the vehicle body will be damaged. ● Do not use the vehicle tie downs to free a vehicle stuck in sand, snow, mud, etc. Never tow a vehicle using the vehicle tie downs or recovery hooks. ● Always pull the cable straight out from the front of the vehicle. Never pull on the vehicle at an angle. ● Pulling devices should be routed so they do not touch any part of the suspension, steering, brake or cooling systems. ● Pull devices such as ropes or canvas straps are not recommended for use in vehicle towing or recovery. If your vehicle is stuck in sand, snow, mad, etc., use the following procedure: 1. Turn off the Vehicle Dynamic Control System (if so equipped). 2. Make sure the area in front and behind the vehicle is clear of obstructions. 3. Turn the steering wheel right and left to clear an area around front tires. 4. Slowly rock the vehicle forward and backward. ● Shift back and forth between R (reverse) and D (drive) (automatic transmission models) or 1st (low) and R (reverse) (manual transmission models). ● Apply the accelerator as little as possible to maintain the rocking motion. ● Release the accelerator pedal before shifting between R and D (automatic transmission models) or 1st and R (manual transmission models). ● Do not spin the tires above 35 MPH (55 km/h). 5. If the vehicle cannot be freed after a few tires, contact a professional towing service to remove the vehicle.

Precautions for Battery Service
NBS003FD
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interference between the window edge and the vehicle when the door is opened/closed. During normal operation, the window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic window function will not work with the battery disconnected.

Precautions for Drain Engine Coolant and Engine Oil
NBS00002
G
NBS00003
H
Drain engine coolant and engine oil when engine is cooled.
Precautions for Disconnecting Fuel Piping ● ● ●
Before starting work, make sure no fire or spark producing items are in the work area. Release fuel pressure before disconnecting and disassembly. After disconnecting pipes, plug openings to stop fuel leakage.
Precautions for Removal and Disassembly ●
● ● ● ●
I NBS00004
When instructed to use special service tools, use specified tools. Always be careful to work safely, avoid forceful or uninstructed operations. Exercise maximum care to avoid damage to mating or sliding surfaces. Cover openings of engine system with tape or equivalent, if necessary, to seal out foreign materials. Mark and arrange disassembly parts in an organized way for easy troubleshooting and re-assembly. When loosening bolts and nuts, as a basic rule, start with the one furthest outside, then the one diagonally opposite, and so on. If the order of loosening is specified, do exactly as specified. Power tools may be used in the step.
Precautions for Inspection, Repair and Replacement
NBS00005
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and replace if necessary.
Precautions for Assembly and Installation ● ●
● ●
●
●
●
NBS00006
Use torque wrench to tighten bolts or nuts to specification. When tightening bolts and nuts, as a basic rule, equally tighten in several different steps starting with the ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is specified, do exactly as specified. Replace with new gasket, packing, oil seal or O-ring. Dowel pins are used for several parts alignment. When replacing and reassembling with dowel pins, make sure that dowel pins are installed in the original portion. Thoroughly wash, clean, and air-blow each part. Carefully check engine oil or engine coolant passages for any restriction and blockage. Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust. Before assembly, oil sliding surfaces well. Release air within route when refilling after draining engine coolant.

PRECAUTIONS ●
After repairing, start engine and increase engine speed to check engine coolant, fuel, engine oil, and exhaust gases for leakage.
Parts Requiring Angle Tightening ●
– – – ● ● ●
NBS00007
Use angle wrench [SST: KV10112100 (BT8653-A)] for the final tightening of the following engine parts: Cylinder head bolts Lower cylinder block bolts Connecting rod cap bolts Do not use a torque value for final tightening. The torque value for these parts are for a preliminary step. Ensure thread and seat surfaces are clean and coated with engine oil.
Precautions for Liquid Gasket
NBS00008
REMOVAL OF LIQUID GASKET SEALING ●
●
●
After removing mounting bolts and nuts, separate the mating surface using seal cutter (SST) and remove old liquid gasket sealing. CAUTION: Be careful not to damage the mating surfaces. Tap seal cutter to insert it, and then slide it by tapping on the side as shown in the figure. In areas where seal cutter (SST) is difficult to use, use plastic hammer to lightly tap the parts, to remove it. CAUTION: If for some unavoidable reason tool such as screwdriver is used, be careful not to damage the mating surfaces.
PBIC0002E
LIQUID GASKET APPLICATION PROCEDURE 1.
2.
Using scraper, remove old liquid gasket adhering to the gasket application surface and the mating surface. ● Remove liquid gasket completely from the groove of the gasket application surface, mounting bolts, and bolt holes. Wipe the liquid gasket application surface and the mating surface with white gasoline (lighting and heating use) to remove adhering moisture, grease and foreign materials.
PBIC0003E
3.
4.
Attach liquid gasket tube to tube presser [SST: WS39930000 ( — )]. Use Genuine RTV Silicone Sealant or equivalent. Refer to GI-45, "RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS" . Apply liquid gasket without breaks to the specified location with the specified dimensions. ● If there is a groove for liquid gasket application, apply liquid gasket to the groove. EMA0622D
Revision: 2006 November
EM-4
2007 350Z
PRECAUTIONS As for bolt holes, normally apply liquid gasket inside the holes. Occasionally, it should be applied outside the holes. Make sure to read the text of this manual. ● Within five minutes of liquid gasket application, install the mating component. ● If liquid gasket protrudes, wipe it off immediately. ● Do not retighten mounting bolts or nuts after the installation. ● After 30 minutes or more have passed from the installation, fill engine oil and engine coolant. CAUTION: If there are specific instructions in this manual, observe them. ●

Connect fuel feed hose (with damper). ● Handling procedure of O-ring is the same as that of fuel damper and fuel sub-tube. ● Insert fuel damper straight into fuel sub-tube. ● Tighten mounting bolts evenly in turn. ● After tightening mounting bolts, make sure that there is no gap between flange and fuel sub-tube. Connect quick connector between fuel feed hose (with damper) and centralized under-floor piping connection as follows: Make sure no foreign substances are deposited in and around centralized under-floor piping and quick connector, and no damage on them. Thinly apply new engine oil around centralized under-floor piping from tip end to spool end. Align center to insert quick connector straightly into centralized under-floor piping.

FUEL INJECTOR AND FUEL TUBE Insert quick connector to centralized under-floor piping until top spool is completely inside quick connector, and 2nd level A spool exposes right below quick connector. CAUTION: ● Hold “A” position as shown in the figure when inserting EM centralized under-floor piping into quick connector. ● Carefully align center to avoid inclined insertion to prevent damage to O-ring inside quick connector. C ● Insert until you hear a “click” sound and actually feel the engagement. PBIC2471E ● To avoid misidentification of engagement with a similar D sound, be sure to perform the next step. Pull quick connector by hand holding “A” position. Make sure it is completely engaged (connected) so that it does not come out from centralized under-floor piping. E Install quick connector cap to quick connector connection. ● Install quick connector cap with arrow on surface facing in direction of quick connector (fuel feed hose side). F CAUTION: If cap cannot be installed smoothly, quick connector may have not been installed correctly. Check connection G again. ●

INSPECTION AFTER INSTALLATION Check on Fuel Leakage 1.
2.
Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leakage at connection points. NOTE: Use mirrors for checking at points out of clear sight. Start engine. With engine speed increased, check again for fuel leakage at connection points. CAUTION: Do not touch engine immediately after stopped, as engine becomes extremely hot.
