A guy I work with told me about Evans coolant, and I'm considering using it in my 455 when the build is done. Has anyone here tried this stuff yet?

From what I understand it's really good stuff, but pricey.

 

Interesting video. Will probably be good for your geography and temp conditions. Would Jay ever steer you wrong?

Like they say though - pretty expensive. I could buy a lot of regular coolant and change it out every 3-5 years for less money though. In my case, it's not worth it especially with the limited use my car gets. Glycol mixed with water is an excellent rust inhibitor and water pump lubricator.

One thing I'd be more concerned about is the high heat that stuff will allow your engine to run. Might also prematurely wear out your hoses, but that's just my opinion.

 

I wouldn't buy it just for the longevity of the product, but more for corrosion protection, and temperature control. Specifically I'm concerned about how those Olds timing chain covers corrode over time, and keeping my big block cool in the hot Arizona summers.

 

Very interesting. Not a terrible investment if it prevents other issues down the road, my timer cover is rather pitted.

Getting all but 3% of the water out might be tough, are the drain plugs on the side of the blocks the LOWEST point in the cooling system? Or do the passages extend a bit lower?

 

I'm going to use this in my motorcycle just to prevent corrosion to the aluminum parts. I would think this would extend water pump replacement.

 

Since I'll be starting with a rebuilt block, I might give it a try. This way I'll only need to drain the radiator.

 

Looks like good stuff. I may try it myself at the right time.

huh? I thought your engine was out of the car...what's holding anything in your rad??

 

If your engine is properly built, and you have the correct radiator, you will only need regular 50/50 quality anti freeze - water mix.
But if the idea appeals to you, what the heck, it's your money and it will do no harm.

The engine currently in the car is a 455 from a '70 Delta 88 which was installed by the former owner when it threw the timing chain. The original numbers matching engine also came with the car when I bought it, and has been on an engine stand. My neighbor is a retired drag racer/speed shop owner, who now owns an engine rebuilding business. His shop is doing all the machining, and we're working on the assembly together. (what a great opportunity that is!) Since I'll be dropping in a fresh engine soon, I thought I might try the Evans stuff. The radiator was cleaned and repaired last summer.
