Part: Interior blower
Operation: How to check the engine cooling fan

In this video we see how to check a mechanical cooling fan; we will start by inspecting the cooling fan drive belt, which should be replaced if we find it dirty with grease or if we find signs of wear on the belt, which may indicate that it may break soon. It is good to check the tension of the fan drive belt and the condition of the tensioner pulley, as well as the cooling fan bearing. Once the engine is turned off, we should rotate the fan by hand; it should move smoothly. If we notice a rotation error, we should replace some bearings, or the entire rotation assembly. If we find some play, tighten the belt, check the viscous fan clutch, then rotate the fan blades, which should not show any resistance. Before starting the diagnosis of the electric fan, remove the negative pole of the battery; check if there is a fuse or relay problem, then check the fan wiring, and the temperature sensor - starting the engine and checking if the fan turns on - if this does not happen the sensor must be replaced, but first check the connectors.
