Hello again all! I have a 2000 Esteem with a 1.8 and I was wondering if anyone else has an issue with their vehicle rising between the halfway point and hot but not overheating? This has confounded me and the person that works on it when I feel it's above my paygrade. I have a factory thermostat that's about a year on. the radiator is about 4 years old and still seems to be running correct. The heater core is good too. I just put on a new water pump (after market) and it still seems to be doing it. The only thing I haven't checked (replaced) is the coolant temp sensor. Could this be the cause of the problem? Oh, it seems that the radiator fan isn't kicking on as fast as it should. When it does kick on, the temp goes back to normal. Please help! Thanking all of you in advance!
