Why does the Volkswagen fan keep running?
1 Answers
Volkswagen fan keeps running for the following reasons: Insufficient coolant: Engine overheating caused by insufficient coolant leads to continuous operation of the electric fan. Radiator leakage: Engine overheating caused by radiator leakage, loose or damaged hoses causing water leakage, resulting in continuous operation of the electric fan. Thermostat failure: Thermostat failure causes the temperature to reach the baseline but unable to send water to the radiator, or sending too little water, leading to engine overheating and continuous operation of the electric fan. Coolant temperature too high: When the coolant temperature is too high, the vehicle's computer automatically calculates the fan speed and duration. The higher the temperature, the longer the fan runs to protect the engine.
