![]() ![]() I am willing to look at other options instead of just sitting back and complaining. I can not see sitting back and waiting for a fix and hope it comes before my warranty expires. Many of us do not want to accept the fact that our truck puke coolant, when doing something a much lesser truck would do with no problem. Too many people are looking for cures that they fall for cleaver marketing in todays society rather than accepting the facts. Thanks Jim.I have been trying to tell people the same thing for years /ubbthreads/images/graemlins/frown.gif. Yes, I'm well aware that Evans NPG+ is some sort of witches' brew of PG and EG. The common thread is that they're *all* ethylene-glycol based. GM's still using DEXCOOL, most other automotive and light truck OEMs (Ford included) are using G-05 or a minor variant of same, and the big-truck and engine OEMs are using some form of LLC, typically OAT but a different mix than DEXCOOL's OAT. When you make your living designing automotive water pumps, it helps to know what fluid you're being asked to pump. ![]() This is not based on internet rumor or random bulletin board postings, but from actually reading the OEM specifications - and building parts for them. Quite the contrary, most recommend *not* using propylene glycol coolants. There's a TSB that's renewed every year that says basically the same thing.Īt this time, I am not aware of *any* automotive OEM or automotive engine manufacturer in the world that recommends propylene glycol coolants. 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. I think the issue was with the older Evans EVANS WATERLESS NPG™ not the NPG+. ![]()
