Best coolant for our 60-70's Mopars?
I've got a couple of cases of EVANS waterless sitting in the garage. My plan is to put it in each one of our cars. Unlike regular antifreeze that is supposed to be changed every few years, the EVANS is supposed to never need changing. It isn't supposed to break down and fill the bottom of the block's water passages with crud like antifreeze that never got changed. I put it in my Duster and Barracuda because it doesn't boil over. That means I don't have to worry about the radiator puking out fluid at the drags anymore if I start to run hot. You can remove the radiator cap without ever having that pressure build up that would turn your car into a geyser. I probably wouldn't even run an overflow tank now except it's required at the track. We're running aluminum heads, water pumps, intakes, and radiators. It's nice to know this stuff will stop them from corroding.
I paid $52 per gallon. If you compare the one time cost of EVANS to the cost of replacing regular antifreeze every few years, it's cheaper in the long run.
