If your car engine is still hot after two hours, there are a couple of possible causes. It could be overheating due to low coolant levels, a broken fan belt, a clogged radiator, a stuck thermostat, or electric cooling fan failure.
To put it in simple terms, all of these parts play a small part in keeping your engine cool. So, if one of those parts malfunctions, you’ll have a hot engine on your hands.
