Waterless Engine Coolant
 

Ran across an interesting Ad in a Trade Magazine for Evans, Waterless Engine Coolant. Sounds interesting and may even lower the engine operating temp, especially in the summer months.

Has anyone used this product in their Jag and what were the pros and cons?

Hi Bill-

There was a thread here on this a little while ago: https://www.jaguarforums.com/forum/x...ant-xk8-83915/

Yep! You are so right, the various comments make for some interesting reading and no definitive answer one way or the other.

Thanks for the link to the thread...

"Water Wetter" is used in my 03 STR, with no problems to date. Came in a two quart container which was poured into the expansion tank.

If a coolant were to reject heat more effectively than the factory installed stuff, the thermostat would simply close and raise the temperature back to normal. That's what it's there for.

Lower coolant and engine temps is not a beneficial thing in any event.

Two nights ago on a rerun of Wheeler Dealer episode on a Triumph TR6 restoration, they used the waterless system and described the procedure and its advantages such as no pressure buildup...The episode will probably be on again this week.

Evans Coolant is a good product. My understanding is that it is named after its inventor; and that John Fitch did some work in its development.
It has practical usage in vintage autos which do not use a pressure coolant system. Jay Leno spoke highly of this product, and uses it in some of his collection.
It is expensive and a bit involved to change over as you have to flush out all the water from your system using pure conventional anti-freeze. I have only one experience with Evans, installed it on a Chrysler product ten years ago, and it is still "working" with no problems or worries. Coolant temperature remains the same as OEM.

The 'no pressure' is not from the coolant itself- it's from modifying the OEM set up to prevent pressure build up. The Evans coolant expands with temperature just like any other liquid.
