so I pulled the T-stat out it was one of thoes high flow 160's, put in a stock type 180 and i was able to drive alot longer
It was about 200 degrese when I got on the interstate.started climbing , got to 220 ,got off interstate started acting up and killed.
got back to the shop ,truned off the a/c and let it idle ,cooled off to 200 in about 10-15 min.
so i'm looking at the car and notice that there is a filler below the grill that cuts the radiater in half and the bumper blocks the lower half.So at speed the air flow is cut in half.
also the intake is being heated by the exhaust tranfer like oldandtired said.
thanks for all the input
