    Question Evans Cool Coolant??

    Has anyone run this in their G8 or another vehicle. It looks like a HUGE PITA to change over to it, but the upside is lower pressures in the cooling system and you never have to change it.

    Evans waterless coolant, prevent engine overheating

    A few people I know used to run this in the Volvo community on the older turbo engines. I never did as I was always having to fix something on the old bricks. Radiators, gaskets, water pumps etc so I never found the value in doing it.

    But in something you will be messing with less like the G8 [in comparison to an old European vehicle] I could see it. Evans has been around a while. You can do a full prep/flush and fill with it as a DIY than what a dealer would probably charge for a Dexcool flush...

    That's my thinking... You just have to get ALL the water out of the system which means running their special fluid that gloms on to water and then putting in the Evans. Since I'm replacing all the hoses, I think now's the time... I'd love to hear from someone that's done it to make sure it's not a huge mistake.

    Jay Leno is a big proponent of it.

    It's on my list for the G8 (installing that 57-pound aluminum intake manifold means a waterpump change anyway), and my LS-powered project truck will get it from day one.

    Once you find a zero-PSI cap, share the P/N. Hard to argue with a waterless, lifetime, zero-PSI coolant that boils at 369 degrees F.

    Wonder what the procedure would be if for some reason you had to drain the system? Can it be captured and reused successfully?

    Yes, I believe so.

    It's a worthless pain in the //

    TO the point that EVANS at one time sued GM because they claimed GM stole part of their patent with the new Dexcool stuffs.

    Here's the biggest issue - sure it might be lifetime chemisty - but it's not great chemisty and it's also not that great a coolant. and nothing else in the cooling system is a lifetime component. so eventually you'll be taking this stuff out due to some other work.

    you can't buy it anywhere (that I know of) so when you do have a leak or something on the side of the road - you have issue.

    I've never used it personally - I refuse to for part of what I say above. I do know some that have and everytime after some years there needs to be some work done on that car - where they have to replace the coolant again.

    Personally for the expense and issue - I'd put dexcool back in - and run it till it doesn't pass the test anymore. (do that ph test strip thing). It will actually go beyond 5 years if you want it to.

    Now if your racing series (if you do that) requires you to use something else - well you have to do what you have to do. But I stay away from evans - and I know of nobody that still uses it. Just like I know nobody that uses redline products.

    They tell you, that you can but they suggest replenishing with fresh. Obviously. I would say if you captured and maybe ensured no contaminates got in the refill it should be good for some time.

    I would still replace the stuff in 5-8 years. Which I would also do with dexcool.

    I decided against it and got some Prestone DexCool or something... Just too much money and not enough benifit.
