I must look to the Mustang gods once again for advise. I just had my lower end re done on my 1990 GT and While i'm Driving after about 30 minutes or less my car is showing a temperature reading about the N on the stock gauge. When I'm at home just running the car in the garage it doesn't seem to get hot at all. Here is what I have done to the cooling system. I have a Cobra/GT40 upper and lower intake. Accufab 75mm throttle body with no coolant spacer. I have a 3 core radiator, 2 Electric fans that run when the car is on. I have replaced the thermostat multiple times and 2 different water pumps. 1 high flow and the other was a stock replacement. Anything else just ask. My question is what would cause a car only to get hot while driving and not in the garage?
