I've got a modified 454 in my 69 Camaro and it runs a little warm. I've heard that if I changed the coolant mix from the over the counter 50/50 to 40/60 or even 30/70 with the adder being distilled water... it might run a little cooler. Has anyone ever experimented with cooling mixes alone and seen any gain? I know water is the best coolant on the planet, but I also know that coolant helps lubricate the system and has additives that will prolong the life of an engine and parts. And of course... it gives protection from freezing. My car is a 3 season restomod, it mainly sleep in the garage during the winter, and I only take it out after a good rain that washes away the salt. Temps in my garage have never gone below 15° and this car has never ever been left outside in all the years I've owned it. So a 30/70 mix won't give me -45° protection, but I think it'll be good to around -10°?
When I say warm, on an 85° day this summer running down the highway the temp gauge shows around 195-200. I have dual 12" eFans that are electronically controlled (PWM) to go on at 195°. I would like to get the temp down on the highway to around 190° so the fans will shut down and just let the 65 mph breeze do its job. If I get into traffic, the temp will go up to around 210-220 and stay there pretty much unless I can't move. The car has AC and air has to flow through the AC condenser and then through the radiator. One other alternative is to add a pusher fan out front, another is to find 2 new eFans that pull more air thru the fins. But before I spend more money on fans I want to think about the coolant mix.
Opinions?
