I installed some Redline Water Wetter in my Revolt.
This is made by Redline Oil, no connection with Redline Performance.
I put in 2 oz in the radiator, with 50/50 Prestone mix. I was at Sand Hollow last weekend and the air temp's were in the 100's. Ask Rickdude, it was hot!
According to my temperature gauge, mounted in the dash. It read 160F to 195F. Even running at 7800 rpm, while climbing dunes.
Did it work?
Well it was hard to tell because I now have the 12" fan installed. I never got a high temp warning light, nor did it spit out of the overflow tube. So I think it did help. Its about $15 a bottle.
