When the engine overheats, the first step is to stop the vehicle safely and turn off the engine. This action is crucial because allowing the engine to continue running can lead to further damage, potentially causing a serious mechanical failure. Turning off the engine helps to reduce the chances of components warping or seizing due to excessive heat.

Stopping the vehicle in a safe location also allows for the opportunity to assess the situation without further risking the vehicle or personal safety. Once the engine is turned off, it is advisable to wait for it to cool down before attempting any kind of inspection or troubleshooting.

Increasing the speed to cool the engine, continuing to drive, or opening the hood while the vehicle is in motion could lead to more severe issues, including potential accidents or injuries due to loss of control or improper handling of the situation. Therefore, safely stopping and shutting off the engine is the best course of action in the event of an overheating engine.
