Evans NPG Lifetime coolant
 

Anybody have any experience with this stuff.? Expensive but supposedly very high quality.

My friend has a race shop and sell lots of it. I think it raises the boiling point to 300 degrees plus. You run a 0 pressure rad cap and no water. He and his race buddies love it.

Do you have to completely flush the Prestone out of your current system to add this stuff in, or can it be put in with just a regular radiator flush and not hurt anything if a small amount mixes with the Prestone???

You have to get almost all the water out of the system and check it with a Hydronomer.? (the battery testing thing)This stuff is supposedly very good for high compression, high temp solid lifter engines (so I am told)

Boiling point is 375 degrees. If there is any remaining water in the system just get it hot and it will boil itself out with the cap off.

It was in my '72 for 10yrs., neat stuff just a pain when you have to drain and refill as you can't use water to top off. Due to this, I just recently switched back to standard antifreeze. For my application driving 2k miles a year to the local cruise-ins, I think it's overkill.

FWIW, It really didn't make any difference in operating temps...even with the A/C on a Fl. summer day.
