Is it idicating an actual overheat or is it just running warmer than usual? Do you have a guage or a light? Most vehicles WILLrun hotter with the AC on because the AC condensor is directly infront of the radiator. Some have an auxiliary fan for this. If you do make sure it is running. Start and get the engine up to running temp. With the hood open peek in to see if you have one or two cooling fans. Watch with the AC on that Both are running in cycles.

We borrowed our daughter's Hyundai Santa Fe to make a trip to the mountains on a 105 degree day. It was doing great on mountain highways until we stopped after about 3 hours.


May be a bad fan or thermal switch not working. The a/c condenser sits in front of the radiator. It may be that the load on the engine going up the mountain is too much for just the air blowing across it to keep it cool, and the car shuts the a/c off to try and keep engine temp down. Cruising along on level ground is enough to keep things cool. Going up the mountain means more engine heat and probably reduced speed, which reduces air flow, especially if a fan isn't working.
Let car cool off, start engine and let it warm up without driving. Monitor temp and fans. When temp gets about normal, look for fan to kick on. Then when turning on a/c, look for the other fan to kick on. Don't let engine overheat. If one or both fans don't come on, start there. Check fan motor not locked up, relay working, fuse/wiring good.

My 1995 Jimmy keeps overheating, what can i do?


Most likely it is the thermostat. Remove the thermostat and see if that resolves the problem. It's fine to run the motor without one for short periods. If it does not over heat you know that's the problem. If it does overheat, replace the water pump.

Dodge Neon 1998 DOHC Overheats when off the accelerator


It sounds like your coolant level may be too low. When you drive up hill the coolant will tend to flow into your engine block and help to cool it down. When you drive down hill the coolant will tend to flow out of the engine block and into the radiator. This may allow the engine block to overheat. I recommend checking your coolant level. If you need to add coolant use a 50/50 mixture of water and antifreeze. If your coolant level is low you may have a leak. Look for the leak while the engine is hot.

I'd also check to make sure your electric cooling fan is working. Let the engine warm up with the car idling in park. Watch to see if the fan ever turns on. If the fan doesn't turn on the problem could be caused by the fan itself, a fan relay, or a temperature sensor.

1986 Pontiac Trans Am Overheating


Its overheating when you go up long hills because the engine is not getting adaquete air in the system. The radiator is angled to get optimal air a certain way. It may overheat but you shouldn't start seeing smoke.
