Question: Engine continues to hum after the car is turned off.

When I turn off my car it continues to hum and doesn't stop by itself. This has only happened twice, and both times I would restart the car, rev the engine and turn it off again, then the engine won't make the noise. My coolant light has also been on although I have filled my radiator with coolant and water, and while driving before the 2nd time the engine noise happened the temperature gauge was moving quickly and randomly from the middle to hot.

It may be another component however, so you should take it in for a diagnoses to be sure.
