I also wouldn't go with the evans fluid, because besides the water problem there are some problems when it comes to cooling high performance engines. That is why Jay doesn't use it in high performance cars. And the Boxster mid engine cooling situation for a LS3 is definitely not that good. Even if Renegade is using that coolant - which i think is just for marketing and not under technical aspects.

Yeah I agree, I'm sure Renegade is promoting and selling it, but it does offer some interesting benefits too so I can see why they may use it. After researching I definitely don't see enough benefit to justify the added expense and hassle if there were a problem. Hopefully just by upgrading the radiators that will be enough to keep this thing cool, if not we can always upgrade later!
Thanks!

Yeah their tradeshow video with Renegade is the only reason I looked into it, definitely sounds great and has great benefits for the right project, but this one is not it

Maybe if you have an old car with a big radiator and a system that doesn't handle pressure well maybe it makes sense, but I see no reason to run it in a modern cars with cooling systems designed around coolant with specific properties. Does it solve a big problem you have thereby justifying the expense and need to re-engineer the system to use it? I would like to see a case where it did...

From the two guys that I know tried it, one just thought it was a good idea and used it on a car that never gets driven. He could have used anything and been fine. The other had trouble with the conversion, as in running much hotter, fans on all the time, etc. Evans first told him that he had not gotten all the old coolant out of the system (it was filled from new, dry components), or that it had air pockets (it was filled with a vacuum system and very carefully bled), then said that it was normal, and that he should run a high capacity water pump, special thermostat and change the fan control temp to keep the fans from running all the time. Those changes were not possible on that vehicle. After spending a LOT of money, he went back to standard coolant and had no cooling system issues. It was an expensive experiment that just added more issues to an already complicated project. I will say this was years ago, and maybe things have changed, but this guy still talks people out of Evans if they ask about it.

I can't say that I have ever had a cooling system issue with a properly maintained system. The issues that I have had wouldn't have been solved by running a no/low pressure coolant. I LIKE the fact that if I have a leak in the middle of nowhere, I can just add water to get me going. With Evans, you need to have coolant with you as water will contaminate it, eliminating its "benefits".

Do a search on Evans coolant and see what you find. If you are absolutely convinced that you need it for some reason, give it a shot. Maybe it will work great. Me, I wouldn't go there.

Just my $.02.
Thanks Qmulus,

I can't speak for other peoples builds and am not sure how long Renegade/Evans have been associated but my guess is they are the reason this question comes up I wouldn't have even thought about it if I hadn't seen that video but as I mentioned, definitely seems to offer some great benefits... do they outweigh the negatives in this situation, not likely but figured it was worth researching.
I appreciate the feedback!
