Waterless Coolant

[Hrant]

Watching Wheeler/Dealer and came across this waterless coolant as a solution for overheating - they were working on a Renault Alpine. Not sure which product they used by I believe the container looked like Evans:

While I understand that the concept and the numbers posted, however if you still get to 200+F at the track doesn't that mean that your engine oil is still running closer to 240+F? The waterless fluid may not boil, but what about the oil?

So no one has heard of this?!

No I haven't until you started this thread.

Since then I have researched through the websites you posted and with the assistance of Dr Google have decided to get some and try it! My race car has a shocking time coping with more than 5 laps on days over 32 deg C. I have blown the same oil cooler water hose as a few others have here at the track on a really hot day because of the pressure needed in the system to stop the water from boiling!

The ability to run lower pressure and reduce the risk of blowing a hose whilst also not having the "water" boil so the cooling system is still working is an added benefit in this pretty hot part of the world currently...

As I see it, it will not stop your car getting hot or "overheating", it will just stop the critical failure of the cooling fluid boiling and then the cooling system stops working because there is now a gas barrier between the engine and the fluid which will cause the engine to now continue to get even hotter to the point of failure.

So the waterless coolant is not a substitute for an adequate cooling system but it could prevent a critical failure of the system by reduced risk of blowing hoses or a boiling system...

I am upgrading to 55mm PWR radiator, twin spal 13' fans, adding 9' spal fan to the external oil cooler and water/meth injection... So as I'm already removing my OEM radiator and upgrading the cooling system, might as well fill it with some waterless coolant as an added measure...

Thanks for the post and introducing this product I had no idea existed!!!

I've been running Evan's coolant for about a year on my Darton sleeved engine. Darton actually recommends Evan's waterless coolant with there sleeves. The trick is to try to get all the existing coolant out of the system before changing to the waterless. If your system is clean you literally can run the system with no pressure at all. The downside is you will run about 9 degrees Fahrenheit hotter than water. I have not tracked this build yet, just spirited driving in 90 degree weather with no issues, just the 9 degree temp. increase. I have a Koyo radiator and lower temp thermostat. I'd love to get some feedback on how it does on the track. Good Luck.
