Engine temp starts to rise when I am on the hwy and I start to go up a grade. I turn on the heater and the temp drops. When I return to level hwy temp stays normal. In stop and go traffic the temp stays normal. Without the heater on car would overheat if the grade were long enough. Also the cooling fans come on when I start the car and remain on until the car is shut off. I know this isnt right whats wrong
have the same problem?
