Why 08 Volkswagen Passat 2.0 Fan Radiator Not Working

Bad Fan Clutch

The fan clutch is a device that connects the fan to the engine and allows the fan to spin at different speeds depending on the engine temperature. If the fan clutch is bad, it will not be able to engage properly and the fan will not be able to cool the radiator.

Bad Thermostat

The thermostat is a valve that controls the flow of coolant through the engine. If the thermostat is stuck open, coolant will flow through the radiator all the time, even when the engine is not hot. This will cause the radiator to overheat and the fan will not be able to cool it down.

Clogged Radiator

If the radiator is clogged with debris, it will not be able to cool the coolant properly. This will cause the engine to overheat and the fan will not be able to cool it down.

Low Coolant Level

If the coolant level is low, the radiator will not be able to cool the engine properly. This will cause the engine to overheat and the fan will not be able to cool it down.

Bad Fan Motor

The fan motor is what actually spins the fan. If the fan motor is bad, it will not be able to turn the fan and the radiator will not be able to cool the engine.
