Why does my car overheat only when the AC is on?
Engine overheating with AC on is generally caused by one of two possibilities. One, is increased engine load caused by a failing AC compressor. ... Plugged or blocked radiator condenser fins, fans not working efficiently or a water pump that is not circulating coolant could all cause overheating with AC on only.
Does using AC overheat your car?
As the AC system moves refrigerant to the condenser, the engine fan blows over the condenser fins to regulate temperature. ... This clogging can cause both the refrigerant and the coolant not to flow properly, causing parts to heat up and eventual engine overheating.
Why does my car overheat when the AC is on and idling?
The most likely cause of the issue that your are having would be a faulty cooling fan. The cooling fans purpose is to keep the radiator and condenser for the air conditioning cool during the idling function of the vehicle. If the cooling fan is not working, this will cause the radiator and condenser to get very hot.
Why does my car stop overheating when I turn on the heater?
The thermostat may not be opening properly, preventing hot water from circulating to and cooling in the radiator. The water pump may be failing and can't circulate enough hot water through the radiator.
Why is my car overheating when the coolant is full?
The primary cause of engine overheating is a lack of coolant. But, if your car is overheating with full coolant, it may be something more severe. Other possibilities include a faulty water pump, a radiator blockage, a stuck thermostat, or even a blown head gasket.
What happens if your car over heats?
Most likely, there's a leak in the cooling system somewhere, and that leak could quickly lead to an overheated engine. In turn, an overheated engine could lead to a massive expense. In all types of cars, the engine is the costliest "system." Overheating can leave it beyond repair in a matter of a few ill-timed seconds.
Why is my car overheating then going back to normal?
If the thermostat fails to open the coolant does not flow to the radiator where it would under normal circumstances be cooled and drawn back into the engine to absorb more heat, get pumped back into the radiator to be cooled and drawn back into the engine again.
Can I remove thermostat to stop overheating?
TOM: Yes, Lee, removing the thermostat does make the car run cooler. But you should never, ever do it. ... When the engine is too cool, the thermostat closes and stops the coolant from flowing through the radiator, so the engine heats back up.
