How do you cool down a heated engine?
If your engine is overheating, do the following to cool it down:
- Turn off the air conditioner. Running the A/C puts a heavy load on your engine.
- Turn on the heater. This blows some excess heat from the engine into the car.
- Put your car in neutral or park and then rev the engine.
- Pull over and open the hood.
Why do you have to wait for the engine to cool?
The reason you wait is that when the engine runs, the water absorbs its heat, and transfers it to the radiator where it is released to the environment, and cools. The water becomes pressurized and the temperature rises to boiling.
Are there any myths about an engine cooling system?
There are many myths and misconceptions about engine cooling, but the truth is your engine’s cooling system must perform a balancing act. It needs to extract enough heat to keep your engine happy, yet maintain enough heat to keep it operating efficiently.
What’s the best way to cool an overheated car engine?
To cool an overheated engine, start by turning off your vehicle and waiting for steam to stop coming out of the hood and the engine to cool down, which can take 30-45 minutes. Once the engine is cool, pop the hood and squeeze the upper radiator hose to see if it’s under pressure.
When does coolant never have a chance to give up heat?
When coolant never has a chance to give up heat via the radiator, it gets hotter and hotter, especially if you’re stuck in traffic. And even on the open road, coolant never has a chance to park in the radiator long enough to give up heat energy to the atmosphere. Never operate your engine without a thermostat!

How can I speed up the cooling process?
Cooling can be accelerated by leaving the key in the on position with the engine off, on vehicles where that causes the fan to run. You can also start, quickly rev (to circulate the coolant via the water pump; 1-2 seconds is a plenty), and stop the engine a couple times while it’s cooling to speed up the cooling process.
What to do when your diesel engine is hot?
Many times a “dieseling” issue is typically cured by messing with the timing. However, then mileage/power suffers, because the timing advance has been reduced for the sake of eliminating the ‘dieseling’ conditon, rather than stepping up to a better grade of fuel. That’s the wrong approach.
