What should you do if your engine starts overheating?

When your engine starts overheating, the appropriate course of action is to pull over safely and turn off the engine. This is the right response because allowing the engine to continue running while it's overheating can lead to severe mechanical damage, such as a blown head gasket or warped engine components. By turning off the engine, you help prevent further damage and can allow the engine to cool down safely.

Additionally, pulling over ensures that you are not putting yourself and other drivers at risk by potentially losing control due to engine failure. Waiting until it's safe to address the problem gives you the chance to evaluate the situation without the added hazards of being on the road.

Driving at higher speeds or keeping the vehicle in motion is counterproductive; it will not help the engine cool down and could actually worsen the problem. Similarly, opening the hood while driving is dangerous and does not take away the critical issue of the engine overheating.
