Joe Boulay 10/1/2012Hello
Many things can cause your engine to run hot. I need more information from you to help you. Is your radiator in good shape, is it missing cooling fins? What does your coolant look like, is it green and clean? If so is it pre- mixed 50/50. Have you replaced the thermostat, if yes is it aftermarket or OEM? Do your cooling fans run? Does your temp go down to normal operating range when you are at highway speeds?
If you can answer me these questions i may be able to help you.
