Leave the radiator cap on until it is cool. Turn the radiator cap. Check your coolant reservoir tank once the engine has cooled enough. Check the engine for leaks.
How does overheating damage an engine?
The heat in the engine causes metal to expand. This puts pressure on the head gasket, which is neatly fitted into place. Eventually, that pressure cracks the gasket. When this happens, water leaks into the cylinders of the engine, which causes damage to other parts.
