Evans Coolant Temps

I agree with Mopowers, you're not pulling enough air for all of them cubes.

I had an old school hotrod with evans in it and it really took the fear of overheating out of the equation. However, my issues wasn't as much as the coolant used as it was moving more air. It had a tightly cowled sbc 350 in it with a mechanical fan and a walker radiator. Once I figured out the right combo to get it cooled by dumping the mechanical fan and adding a proper sized electrical puller fan, it was maintainence free.

There are strict directions on how to use evans coolant and I'm assuming you followed their directions. Evans cannot be contaminated with anti-freeze or straight water as it renders it pretty much useless. If you didn't have your system professionally prepped and all of the previous anti-freeze removed, its a crap shoot whether it'll be effective.

What I like about evans is that iirc, the boiling point is 375*, whereas the boiling point of a 50/50 mix is around 225* and depending on the rated pressure on the radiator cap used can reach around 250+-. That's quite a large difference of 125*-150* in its boiling point.

So with that said, stick with the evans, $50 or so a gallon is too much just to toss.

Either find a way to move more air or look elsewhere, like air pockets in the system which is easy to burp.

I don't think evans is your problem. If there was a vendor in my area that could prep my engine, I'd go back to using evans, it's a lifetime coolant.

I got a little wordy, sorry. Hopefully this helps.

Good luck! :usflag:
