Symptoms: When car warms up to operating temperature the temperature gauge slowly climbs and begins to overheat, either idling or while driving, where the needle starts passing the 1/2 way mark on gauge. Car slowly cools as it maintains a cruising speed while I crank the heater.
I recently replaced the radiator cap, but it didn't help; still slowly overheating.
Coolant levels appear normal. I don't see or smell any leaks. Radiator feels warm, upper hose warm and firm but lower hose feels fairly cool. No debris around the radiator. Heat is very warm, so that isn't affected.
I had past issues with the cooling fan not coming on at idle and generally in the summer I'd be running the A/C anyway so the problem would only manifest on a hot day if I'm idling and not running the air. Temperatures are cooler now and even at milder temps like in the 60s, the temp will start creeping up after longer drives.
I'll likely replace the thermostat next. Any other ideas?
