I had to go to a Be Cool aluminum radiator on my car to keep the running temps to 180-190. A recored 4 core stocker would not keep the temps below 210. With the Be Cool, my car runs at 180 on a 95 degree day.
lol Larry, good memory! I run 100% or as close as I can get in my wife's Expy and my E350 Vans for many years now. Back in the day I ran 100% in the Buick too. When I had cooling problems with the 350 I went to 100% water and saw no difference. Now with the 455 I'm running 100% water temporarily as I still have problems when I run the A/C. I'm sure its the radiator. When I get it all sorted out I'll go back to 100% antifreeze. I know ya think I'm nuts p
