Reply to "Waterless engine coolant"

TP, know that I have changed absolutely EVERYTHING possible in the Pantera cooling system including the cylinder heads, and the ONLY thing that changed the running engine temp was a bigger aluminum radiator. My temp drop was 12 degrees F. So if you're trying to lower engine temps on long runs, changing the rad is the right thing to do. If you're just dealing with a leaky unit, the alloy rad is also 1/3 the weight and holds more water than stock.

With alloy rads, you will need to check your local water quality- some areas in the U.S are so corrosive, a piece of scrap aluminum left in a glass overnight will attack aluminum like it was acid! Most alloy rad-vendors include a bottle of No-rosion additive or something similar. There are other definitive tests you can do at home, too.
