So far so good. Need to run on highway to see if it makes a huge difference. But in 90degree weather my blown 496 BBC stayed below 205 degrees in traffic. It’s normally 210-220 easy.

It works ok, I think if you flushed your radiator completely and filled it half and half it would probably work.. I didn’t see much of a drop in my high compression engine. Just a few degrees…

This product worked as advertised on my 2004 Corvette Z06. I saw water temperature reduction of 20+ degrees on the autocross course.

This made Zero difference in my radiator water temp. I run a mail vehicle and at 85 deg and 85 % humidity the car overheats at a certain spot in the route. This product changed nothing.
