What is the first action to take if your engine starts to overheat?

When an engine starts to overheat, the immediate priority is to prevent further damage to the vehicle. Pulling over and turning off the engine is the best first action because it allows the engine to cool down naturally without running the risk of causing serious harm due to excessive heat. Continuing to drive or revving the engine can exacerbate the overheating situation, potentially leading to engine failure or other severe mechanical issues. Opening the hood to check the coolant might provide additional information, but it is crucial that the engine is turned off first to avoid any accidents or injuries from steam or hot components. By stopping the vehicle safely and turning off the engine, you are taking a responsible approach to managing the overheating problem.
