Does turning on the heater cool down your car?
Yes, using your heater in the car will help cool the engine. It won’t help much, but it does take some heat out of the hot radiator water. The same hot antifreeze that circulates through you radiator and engine also circulates through the heater core that provides heat to your car’s cabin.
Does turning on the heater help an overheating car?
Turn on the heater. This blows some excess heat from the engine into the car. While it’s not ideal on a hot summer day (which is when most vehicles tend to overheat), it does help cool the engine down. This makes the fan and the water pump work faster, which pulls more air and more water through your car’s radiator.
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.

Does turning on the AC cool the engine?
Air conditioning actually creates more engine heat in the engine compartment as there is more strain on the engine to operate the AC compressor. Either the fan operates at a higher speed to combat the extra engine heat generated, or there may be a secondary air conditioning fan that runs to provide extra cooling.
How long does it take for a car engine to cool down completely?
It typically takes a solid 30 minutes for an engine to cool down enough for it to be safe to handle. If you’d rather let a professional handle the problem, it’s time to call for a tow truck. Once the engine has cooled, check the coolant tank.
