Evans Waterless Coolant

[secondchance]

Has anyone heard of this?
Evidently Jay Leno has been using this according to this video. Your thoughts?

I believe this is the guy that invented the reverse cooling system that was used by GM and the subject of some nasty litigaton.

Wow. That was 9 years ago. I wonder how it turned out?

As far as the coolant. I'm very interested.

It's expensive, but looks worth it. Who wants to go first? If it's good enough for a Bugati should be for a ZR-1 right?

very COOL . nuk nuk. I'm interested

When I purchased my 95 it already had the evans in it. I have left it in. While I haven't had any problems with it overheating i dont see the results they have posted. All four of my Z's seem to run the same temps and the other 3 are just running the regular"green". I continue to use it hoping it does eliminate any hot spots as they claim. One differance that may or not be related is that you can notice what appears to be an antifreeze smell but there has never been any leaks and the level has always been full.

I know this doesn't answer any questions or give any advice it's just been my experience.

Darton seems to recommend it for use with their MID sleeves. They have a drop down in their tech for Evans. BOB IS THE OIL GUY FORUM has some interesting reads regarding it also.

I am not so concerned over overheating or looking to achieve lower operating temperture. My experience with LT5s have been build-up of debri between the AC condenser and the radiator causing overheating. Keeping this cavity clean, as we all know, can avert any overheating concern. Also, having drilled one 1/8" hole through the 180 deg stat effectively dropped my operating engine temp from 203 to 225 to 185 to 213 (on a hot DC 100 degre day in a stop and go traffic) with AC running. However, prolonged stoped situation I noticed temp slowly climbing beyond.
What peaks my interest in this product is alleviating sludge build up inside which I believe is from corrosion and separation of rust inhibitors from the coolant. Last time I removed the throttle body coolant plate I noticed a layer of green substance resembling play-doh lining the surface.
If this stuff has the same or better latent heat characteristics as water and non-corrosive then surely would be a better choice for our all-aluminum LT5.
What concerns me is that I have no idea what this is.

I guess it needs to be tested with the LT5 head gaskets. Isn't that the issue with Dex-cool, it eats the head gaskets?

Although they don't tell you what this is composed of if this liquid is inert as they claim and non-conductive (as in electrical) then should alleviate any concern for head gasket.
