Car running hot but not overheating

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. When you changed the thermostat, did you ensure that any air pockets in the cooling system were fully purged? This is one area of concern that can make overheating on some level possible. Under what conditions does the overheating occur -- or high temperature, at that? You'll want to see if it's during highway driving, local driving or just sitting idling. This can help pin point the failure as to possible causes. Lots of guesses - from base engine cylinder head breaches to water pump circulation to erratic fan operation - even if it "works" - maybe not always? A lot more drilling down needed and some hands on testing needed to figure out what is going on. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
