EVANS: MANAGING YOUR HEAT

It’s a hot, humid day in July and you’re taking your car to a show. The air isn’t moving, and traffi c isn’t either. Your temperature gauge is moving though, an, as you watch it climb, your blood pressure rises with it.

Do you pull over to cool down, or sweat it out and nervously watch the rising temp gauge? You think you smell coolant, and hope it’s not already escaping under such high pressure. What could happen next? Well, the answer depends on the type of coolant you have.

A water-based coolant, nearing its boiling point, forms vapor and builds pressure. Vapor pockets form, increasing the metal temperature, and the coolant gets even hotter. Very quickly the boiling coolant fi nds a way out through the weakest point in the cooling system. The day you’ve looked forward to is ruined and turns into a messy job of changing coolant or other cooling system repairs.

If you used Evans Waterless Coolant, the story has a diff erent ending. With a high boiling point of 375° F, Evans will not form vapor, build pressure, or boil out. You most likely won’t come within 150 degrees of reaching that critical, aka failure, point. Evans remains liquid, ensuring constant liquid-to-metal contact, and prevents hotspots that lead to excessive metal temps.

Even under extreme conditions, the coolant will absorb more heat, and keep metal temperatures consistent and manageable. The gauge may reach a higher temperature, but without the anxiety or consequences described above. With that, you can enjoy your day as planned – without the disruption, embarrassment, or costly repairs.

Common FAQs about Heat Management with Evans Waterless Coolant Will Evans lower my engine temperature?

Under normal operating conditions Evans typically runs about the same, or at slightly higher temps. The ability to lower the operating temperature depends on multiple factors, primarily coolant fl ow volume and air fl ow temperature. Certain systems that use incompatible components, have an existing problem, or are poorly designed could run hotter. For example, multi pass radiators will result in higher temperatures due to decreased coolant fl ow volume vs. large tube multi row radiators that improve coolant fl ow.

Why would Evans make my engine run hotter?

A system highly optimized for water, with restrictive fl ow and high-pressure diff erentials, can cause slower circulation with Evans Waterless Coolant. If the coolant is held longer in the engine, it can pick up more heat, and Evans can draw more heat away from the metal, like a sponge, and the “engine component temps” are actually improved and stabilized.

Will Evans make my engine run too hot?

No. People often think the temperature gauge reports engine temperature when it really is only reading the coolant temperature. With water-based antifreeze, the temperature gauge must be watched because when it gets too hot, the antifreeze will boil and allow the engine to overheat. Evans Coolant will not create vapor; build pressure, or boil out. To discuss your vehicle specifi cally, call the Waterless Tech Line at 888-9902665.

Area A is an area of high thermal energy transfer, where Evans Waterless Coolant is able to remain in liquid form to continue removing heat from the head. In area B, a layer of steam has formed either due to extremely high temps, or an inaccurate coolant mixture blend which didn’t increase the boiling point suffi ciently.
