Has anyone used this coolant in their C2?

IMO No need. Conventional coolant does the job complete.

Mike Cipolla

Conventional coolant does do the job in the cooling aspect, however the water it's mixed with as you know causes metal to rust. As our cars set through the winter, year after year, the additives in antifreeze that help prevent corrosion settle.

I could see this as a good upgrade.

Higher boiling point
Lower freezing point
Low pressure system
Claims to last as long as engine (one time purchase)

Waterless, cool. I'd try it out. Premium $, but what the heck. I'll buy it this summer. If you don't like it, flush it.

Avispa

The Ford guys have us beat by about 10 years with this stuff. It was written up in Muscle Mustangs anf Fast Fords magazine in 2003 or thereabout. It's non-aqueous propylene glycol. Completely safe and non-toxic (it's actually used in food processing). Other than the expense, the only downside is that the stuff has to remain completely free of water to get the high boiling point benefits. It's also available from Amsoil.

On last night's episode of Wheeler Dealer they put the stuff in a TR-6 after flushing/prepping the coolant system. In addition to the no-rust properties and expanded operational temperature range - it apparently doesn't pressurize the cooling system. On the show, big Edd snatched off the radiator cap after running the car up to temp with the stuff in the radiator and no hot spray - no hot anything in fact.

The Evans product is on Amazon for about $35/gallon.

That Wheeler Dealer episode is where I saw it first too. Researched it and saw that Jay Leno has been using it in some of his collector cars for years.

It does cost around $40 a gallon, however that a one time thing.

I really like the low pressure ability of it. No catch cans or expansion tanks

Easier to replace a battery

Frankie the Fink

The one downside is that you have to COMPLETELY flush any old coolant out of the system... Evans offers their "prep fluid" for this purpose - about $25/gallon.
I may look into this before summer's heat hits for the '61 - what I wonder is how well your cockpit heater will work with this stuff in the winter - the same I guess??

hmmmmm... if i had your $$$$ i'd burn mine... i reckon i can buy a lot of new antifreeze every 3 to 5 years for what it will cost to changeover to this stuff.

Bill, I am thinking more about the corrosion inside the engine block and rest of system than the cost of it. If you have ever drained antifreeze from a old car you will see what I mean. Plus it would be one more thing it never have to change down the road.

Is it necessary to switch to this stuff? No of course not.
If I had to fill a diesel engine system with it (15 or more gallons) it would be a hard price to shallow at $40/gallon. But a corvette wouldn't hurt that bad.

I might consider changing over in the spring. Need to research more about it

Maybe if you are lost for days somewhere (not knowing where because you are lost) if it is safe and used in food maybe you can eat or drink it to stay alive? something to think about.

Frankie the Fink

In fairness the regular anti-freeze corrosion inhibitors work well. However, they eventually settle out of the mixture and that is when rust begins. Regular changing of antifreeze prevents that. The advantage to me of the waterless stuff is the greater operating temp range and little-to-no pressure in the cooling system.

I have used Evans coolant in my 60 vette for the last 6 years, runs at 160 degrees all the time , even in 100 degree days here in south Georgia, this car is a daily driver so it it is well used including trips to our other home on lake Ontario in upstate New York. Any time I dry a system out I replace it with Evans and have not had the first problem period. A terrific product and great people to deal with.--Bill

The non-pressurized part of it is appealing. The thought of permanently removing the expansion tank to access the battery is a very very nice thought.

Mike Ward

Be aware that the cooling system will need to be modified to prevent pressure increase as the engine heats up. The Evans coolant expands when heated just like any other liquid. Not sure I'd want to be the first one to experiment with running a Corvette at zero pressure.

wmf62

yeh, but at about 4+ gallons to fill a dry system it's a bit out of my reach unless Tom will share some of his Obama Bucks...
Bill

wmf62

how are you gonna fill the system, splice a filler & cap assembly into the top radiator hose? the expansion tank does serve to scavenge the air out of the system too.
Bill

WHY?

I think wanting to do this to a C2 comes from boredom. They have run out of affordable stuff to mess with.

My mouse trap is fine.

Frankie the Fink

I have no idea what you are talking about here.

Every vintage Corvette on the planet is already set up to handle either 7lbs or 13 lbs of pressure depending on how its equipped.

If waterless coolant is less pressure when at operating temp I don't see modifying a single thing.
