Anyone using Evans Coolant pros and cons?

 

Pros are much higher boiling temp and no glycol I believe so it's track safe. That's about it. But a good cooling system shouldn't have to depend on the type of coolant just to stay cool. Good water pump and radiator that's adequate for the engine is key.

 

Heat capacity of Evans is lower than that of 50-50 antifreeze, so the engine will run at a higher temperature.

It will not boil over, so the higher temperature will be stable.

If you want to maintain or decrease your current temperature you must upgrade the radiator.

 

WHICH "Evans Coolant"??? They sell several versions. They're all really expensive. The big deal is that they contain some--or all--propylene glycol instead of ethylene glycol.

I don't understand what's so miraculous about propylene glycol. You can (and I have) bought PG for far less money than Evans under the Sierra brand name.

Other than bragging rights, I don't see it as necessary from the financial or the practical aspect. These cars run fine with what was recommended when they were built.

 

Please cite for a fact your source of information. The fact is, Evans Waterless Coolant is between 80% - 85% ethylene glycol.

It plays a role when tracks don't allow conventional coolant. The silicates I believe are hell to clean up if you leak

 

Yeah, that's one of their several formulas--which was my original point, emphasized in bold print. In this case, they've listed less than 87% of what's in the bottle. Normally, I'd expect them to have to list Propylene Glycol if there were any. However, Evans is known to hide their "proprietary" formulation whenever it's convenient for them to do so.

Here's another:

that "blend" is almost certainly Ethylene and Propylene. Evans doesn't list MSDS/SDS on their web site that I can find.

So again they hide which glycols are in their product--but the most likely are Ethylene and Propylene.

It's no surprise that they want consumers to not know what they're buying.
