![]() See that bit in the owner's guide that says something to the effect of "don't use propylene-glycol-based coolants"? That's the part. Thanks again, this is why I love this sight /ubbthreads/images/graemlins/smokin.gif. If they do not come out with fix soon, I may try Evans. Mine does puke but runs fine and I do not get cross contamination, have done oil analysis every oil change. I have to take mine in for updates and I will point it out again, incase it gets worse later. I assumed you were using NPG+, my statement was to the other guys saying that no radiator or water pump manufacturer recommended Evans guess I worded poorly. If I can complete a little project I'll post the results if positive. This winter my 6.0 will be removed for a few "upgrades" and we plan to test the EGR for pressure drop in order to test my theory. It just seems strange that some 6.0's never lose coolant and others will just driving around the block?Īdding insult to injury, some 6.0's have bad or impropoerly installed head gaskets. ![]() Its only my theory but it seems some EGR systems aren't flowing enough coolant for some reason. Our tech installed an EGR gauge to see whats going on and from the driver 1200F is REAL common. After adding Evans it no longer loses coolant. Dragging a 13Klb gooseneck around loaded keeps it in situations where before it would loose coolant daily. The 05 Tow Boss w/4:30's is worked hard in and around the cities everyday. How long have you had the Evans in and have you had the truck in situations that would cause it to puke? There have been mixed reviews as to whether head gaskets and studs even fix some engine and most run great but puke. I think the older NPG is really only recommended for racing applications. Where does it say ANY OEM recommends against using Evans? Its chemical & physical properties far exceed Ford Gold money coolant.īBS forums easily spread false or misleading information simply by "I heard a friend that knows a 2nd cousin. To much heat (exhaust gases)and not enough flow (coolant) equals small steam explosions which is what throws the coolant out and all over your engine.Įvans coolant has several properties which help prevent these little problems. From a physics point of view, Ford/IH or both should know better than this. The EGR cooler is a screwed up design no matter how you look at it. The 6.0 hasn't lost any coolant and appears to run slighty cooler. We put Evans in one of our 05 Tow Bosses just to see if it would resolve the coolant flash boiling issue and it did. I was really looking into using the Evans as my vehicle will puke but only under hard load and everything else seems great and it does not seem to get any worse. The NPG+ addressed the issues with the older version and if you check their sight, you will see that they only recommend the NPG+ for diesels. I have seem this was discussion before and it has to do something with viscosity and wearing out pumps, as I understood it. The think the older NPG is really only recommended for racing applications. However, if you’re unsure of which fluid to use to keep your vehicle performing at its best, refer to your owner’s manual or ask a trusted mechanic.I think the issue was with the older Evans EVANS WATERLESS NPG™ not the NPG+. We selected five of the best-rated antifreeze and coolant fluids that are also compatible with most vehicle makes and models. When browsing the various types of fluids, it’s easy to get confused. Running your car on older deteriorating antifreeze or coolant can cause acid buildup, scaling and reduced resistance to extreme temperatures. The longer you use coolant, the more its useful chemical properties break down. Performing routine maintenance on your vehicle’s cooling system will ultimately prolong the engine’s life. Antifreeze also fends off rust and corrosion, helping to extend the life of water pumps, radiators and other cooling system components. In the winter, the chemical formulas in antifreeze also prevent water and moisture from freezing, which can damage the cooling passages inside the engine and other components just as it would the pipes in your house. Combustion engines generate lots of heat, and coolant, a mixture of antifreeze and water, plays a vital role in regulating their operating temperatures.
