Evans coolant

[Garage Guy]

I am thinking of using Evans coolant in my Forte built 306. I was just curious if anyone has used Evans coolant? I am wondering about its performance and any pros and cons out there of people that have used it. Thanks

I have no experience with Evans. Not to be a wise guy but I have to ask why unless you plan to run the car on a track where they prohibit the use of Glycol based coolant? There is nothing exotic about a 306 Windsor and the FFR radiator (especially with a fan shroud) is more than adequate to keep it cool. Personally rather than spend nearly fifty bucks a gallon for the Evans I'd go with an aluminum compatible Glycol antifreeze for $15 per gallon from one of the name brands like Zerex, Prestone, etc. along with $1/gallon distilled water. But that's just me and everybody knows I follow the K.I.S.S. philosophy ;)

I've run Evans. Actually works well BUT.....

It's really a light oil based product. If it leaks it's messy but since the system isn't pressurized there shouldn't be the same opportunity for leaks. It does not mix with normal Glycol coolants. If you switch from Glycol to Evans there is a system flushing procedure. If you play on race tracks and spring a leak the track maintenance guys will not be pleased.

I ran it for about 5k miles in a roadster that I bought. Changed and flushed the coolant system when I switched motors, filled with Glycol based coolant.

I won't run it again not that it doesn't work or is bad, it's just bad for me.

Jeff K offers really good reasoning for sticking with the standard.

On a street driven car there are ZERO advantages, unless you like have a much lighter wallet.

Won't the lighter wallet make the car faster? :)

Thanks for all the advice everyone. The reason I was considering going with the Evans is because of the lack of pressure that the Evans coolant does not build.not really because I think my 306 is all that exotic. That's why I posed the question I wanted to know if there were really any huge advantages to it. To justify the exorbitant price .One of my main concerns was I'm not able to find it locally anywhere and I was thinking if I was on the road and sprung a leak somewhere it could really cause a problem finding it and don't want to have to carry extra bottles of it around on road trips. From the sounds of it it doesn't sound like it's worth the trouble or the price.

It does have a higher boiling point, thus less pressure. It is also not as corrosive as water. However, it does not cool as well as the water/Glycol mix and as mentioned it cannot be mixed with water.

I had considered it at one time, did the research and then decided not to use it.

I used it in my GTO for years. Jay Leno uses it - check out his videos. Biggest positives:
1. It will not eat away at aluminum parts.
2. It boils at 375*.

I liked the higher boiling point for my 469cid stroker. It was peace of mind knowing if I get stuck in NY traffic and the car ran a little hotter than usual, I wasn't going to blow a hose.

It's lifetime coolant. I drained it into a clean pan and reused it several times when doing engine work.

Oh, and you have to use their special flush to get 95% of the old coolant out in order for it to work right.
