While discussing water pump rebuilds w/George @ AJP
he was touting the benefits of a non-water based coolant
by Evans.
www.evanscooling.com/products/coolants
Anyone have experience or comments on this product??

Asked at the local radiator shop when they were doing my radiator and fuel tank. They said the best thing is regular anitfreeze changed at regular intervals. He said extneded life coolant is neglected and wears out.

Saw the ads for Evans, cost is very high.

I wonder also.

Extended life coolants and lubricants are really best left to high utilization rate vehicles. Low utilization rate vehicles need their coolants and lubes changed at least once a year regardless of mileage and this is rediculously expensive when one tries to use these modern high tech, high mileage products.

Thx for the replies, fellas. There were a few aspects of the product
that bothered me.
1. Successful installation requires total evac of all water and water based
coolant. Mfgr recomends their own prep product @ about $40 to
prep the system for the coolant. Add 2 gals coolant $80.
$120 ttl initial product investment (+ shipping).

2. You're out on a weekend convoy with the gang and develop
a system leak and dump half your coolant. Good ol' duct tape
and hay wire patch it up so you can limp back on in-GOOD.
BAD-you cant just pull up a bucket of creek water and top it off.

3. Ethylene-glycol coolants have been performing well for decades-
a guy just needs to perform reg cooling sys maintainance .

I always use distilled water in all of my vehicles. A 50/50 mix is sufficient.

Most, if not all, anti-freeze manufacturers recommend plain tap water for the mix. Distilled water is actually a strong solvent and can be corrosive; the antifreeze includes chemicals to deal with the minerals in tap water.

I'm quite certain I've seen distilled water called for when changing long-life anti-freeze (if not using the 50/50 premixed stuff). I used distilled water when changing the Dexcool in my Suburban.

How does distilled water become a stong solvent? I thought it was perfect for radiators and steam irons.

Steam irons and batteries, yes, but different issue from cooling systems. Water is naturally a strong solvent; that’s one reason why it picks up so many minerals in the ground and becomes ‘hard’. If the anti-freeze manufacturer recommends distilled water, use it. I’m not sure what you mean by ‘pre-mixed’, as the anti-freeze (ethylene glycol) is my area is at 100% strength. Regardless, in the overall picture, it probably doesn’t matter much which water you use as long as it is clean.
