Engine Cooling problem
1999 Saturn SL2 4 cyl Two Wheel Drive Automatic 130000 miles
Works great majority of the time, car reaches temp (about a 1/4 on coolant temp gauge where its been for 10 years) and stays there.
Increasingly often, lately once or twice a week, when at at a stop and idle, car starts overheating and gauge rises slowly to half or higher and starts to run rough. Once moving again (getting air flow?) Gauge goes back to normal.
Any help on narrowing it down appreciated, is it cooling fan? Sensor? Thermostat?
