Turning on the heat may be the last thing you want to do on a hot summer day, but it can pull hot air from the engine compartment and cool the engine. The coolant level is shown by indicator lines on the reservoir. If too low, simply add the appropriate amount of coolant and reattach the cap.
Does running your heater cool your engine?
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.
Should you turn on the heater if your car is overheating?
Turn On The Heater
It sounds counterintuitive, but Reina recommends turning on the heater. It draws warmth away from the engine and into the passenger compartment, lessening the burden on the engine’s cooling system. In certain circumstances, that may be enough to reverse the overheating, he says.
How can I cool my engine fast?
One quick trick is to throw your vehicle in neutral and give the engine a couple of light revs in hopes that it will make the water pump and radiator fan increase in speed to help cool off the engine. (Also, do your best to let your vehicle coast–having to repeatedly brake actually is added strain on your engine.)
Does heater use more coolant?
A: It takes a while for the coolant to get to the proper temperature before the heater core can produce enough heat. Since the heater pulls heat from the engine, it takes time for the engine to warm up. The cooling system thermostat restricts the flow of coolant to allow the vehicle to warm up faster.
How do you start a car after it overheats?
What to Do When Your Engine Overheats
- Kill the A/C and crank the heat. Immediately turn off the air conditioner to reduce stress on the engine. …
- Find a safe place to pull over. Pull over and shut off the car. …
- Check and add coolant (if you have it). …
- Restart the engine.
Why is my car overheating when the coolant is full?
An engine coolant leak internally or externally reduces the level in the system, preventing proper cooling. Blown head gasket. A blown head gasket can be the cause or the result of car overheating issues. Coolant can leak out, air gets sucked in, and the engine temperature needle wraps around to full hot.
Can I drive my car after it overheats?
Driving your car when it’s overheating can cause serious – and sometimes permanent – damage to your engine, so it’s best to stop driving as soon as possible. Pull over and away from oncoming traffic, then turn off the engine. Open your hood (or call for help).
How do I know if my engine is damaged from overheating?

What happens if you keep driving an overheated car?
If you continue to drive an overheated car, you run the risk of warping your cylinder heads. This result is decreased power, misfiring, and excessive oil burning. However, cylinder heads aren’t the only things in your engine that can melt; other components like sensors, belts, and wiring are also at risk.
How long does it take for an engine to completely cool down?
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. It’s usually a translucent plastic tank near the radiator.
What are signs of a bad thermostat?
There are several common symptoms associated with a bad or failing thermostat that will alert you that service is due.
- Temperature gauge reading very high and engine overheating. …
- Temperature changing erratically. …
- Coolant leaks around the thermostat housing or under the vehicle.
Can I pour water on my engine to cool it down?
No. That’ll lead to thermal shock and could result in mechanical stress and even cracks, because pouring water on a hot engine will lead to a sudden drop in temperature and the resulting contraction of metal parts. The engine needs to be left alone at the ambient temperature to cool down slowly and avoid all this.
How expensive is it to replace a heater core?
Replacing the heater core can be an expensive job, and usually costs between $564 – $927 for parts and labor. The parts aren’t particularly expensive, normally costing $80 – $234, but the location of the heater core means that labor costs tend to be quite high.
Can you drive with a bad heater core?
You can still drive on with the condition; however, you should not, for a long time. The heater core uses the engine’s coolant, and a faulty heater core affects the cooling effect which then raises the temperature. Not curing the issue and continue to drive the vehicle this way can lead to further engine damage.
