A detailed video lecture on the car's cooling system. We'll explain how the coolant temperature sensor works, why sensors are available with two or three contacts, and where the engine temperature information on the instrument panel comes from. Who controls the engine cooling fan, and why the fan might not work. We'll explain the connection between the coolant temperature sensor, the ECU, and the engine fan, and how to troubleshoot the problem yourself. We'll also explain how to properly diagnose fan and relay speeds, the relationship between engine temperature and the temperature gauge on the instrument panel, and, most importantly, how to avoid engine overheating.
