2000 Mitsubishi Galant Question: Engine still running hotter than normal
My car has been a great car until I started to have problems with it running hotter than normal, never to the red, but above normal. I have had the thermostat replaced, just replaced the water pump along with the timing belt and serpentine belt replaced. Also had a tune up and replaced spark plugs and valve cover (it has about 108,000 miles on it). Still having problems with the car running hotter than normal, especially after driving on the freeway or after about 20 minutes. My shop suggested it could be the radiator, but don't want to replace that too and still have a problem. Is there anyway to test the radiator to see if it is plugged or not? If not the radiator, what else could it be? Okay, just had radiator replaced today and the mechanic said it was split. Well, still the same problem, running hotter than normal. I am at my wits end! Don't know what to do next, sell it? - Visitor

For the last month, the temperature gauge has been running hotter than normal. Took into dealership service department and they said thermostat was going out and they replaced it, along with a flus...
