What happens if you drive with a hot engine?

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 can I cool down 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.)
