Thanks for the input... Still working on the problem just had to take a few days away from the garage for a school district science fair... Got to take a look at the fan... One of my friends (?) asked if I had the fan in backwards... Got to get back to the garage in the morning.... Anti freeze I put in said to use a 75/25 mix.... Never drive the thing in rough weather so going to pull the thermostat tomorrow and see what affect that has.... Got to be that darn sensor... could kick myself for losing track of the old one....
