What action should you take when your engine overheats?

When your engine overheats, it is essential to pull over to a safe location, turn off the engine, and allow it to cool down. This action is crucial for several reasons. Firstly, turning off the engine prevents further damage from occurring due to excessive heat, which can lead to severe engine problems or even total failure. Secondly, being in a safe location ensures that you do not pose a risk to yourself or other road users while waiting for the engine to cool.

Allowing the engine to cool is vital, as attempting to drive the vehicle while it is overheating can exacerbate the situation, leading to more significant issues. Additionally, opening the hood to add water or coolant when the engine is hot could cause injury due to steam or boiling fluids.

The other options do not effectively address the safety or mechanical integrity of the vehicle during an overheating incident. Therefore, safely pulling over and allowing the engine to cool is the most responsible and protective action to take in this situation.
