waterless coolant for classic cars

[Keith W.]

Saw this yesterday just thought I would pass it on, The guy at the demo filled the car rad up with this stuff let the car come up to operating temp them removed the cap, nothing happened.

so it claims no freezing, no over heating and no corrosion

Am sure you guys must have something similar in the US


just found this with jay Leon just copy and paste into search engine should pop up

Yes, it's been discussed to death on just about every enthusiast web site including this one.

The product and it's claims do not stand up under anything more than superficial examination.

GM specifically DOES NOT recommend polypropylene glycol coolant in any concentration, and Evans is straight polypropylene glycol, maybe with a corrosion inhibitor package, maybe not, who knows?

Straight polypropylene has less heat capacity than a 50/50 blend of ethylene glycol and water, which is certainly not a good thing and will result in higher coolant temperatures in extreme conditions.

The best blend of coolant for vintage Corvettes is Zerex G-05, which is current OE in Ford and Chrysler products. It's the only current OEM coolant that offers excellent protection to solder, which is common in vintage cars, but is no longer found in modern cars. This HOAT coolant was developed by BASF and was first used in all Mercedes vehicles beginning in the eighties.

I don't know what brand names are used in the UK, but it is tinted an amber color.

Evans is just another aftermarket snake oil that is widely peddled, along with all the other snake oil for your crankcase and fuel tank. A 50/50 ethylene glycol/water blend with 15 psi pressure cap boils at 265F, so even if your coolant gets up to 230 in extreme conditions, there is no need to be concerned as long as your coolant system is in good operating order because you still have over 30 degrees boilover margin.

Re: waterless coolant for classic cars

I did a good deal of research on this last summer when I flushed the entire cooling system. Thanks to Duke and others I went with the Zerex G-05.
I cut it 50% with distilled water. It's just fine! I installed a Robert Shaw Thermostat at the same time.
