If the cooling fan motor does not work, airflow through the radiator will decrease, the temperature of the engine will increase to unacceptable levels, and the engine will overheat. Under most circumstances, there is not enough airflow through the radiator without the assistance of the cooling fan. A vehicle
should not be driven if the fan motor is not working correctly and the engine is overheating. Serious damage to the engine can occur if it is allowed to overheat for an extended period of time. If the fan motor fails during driving, it may be possible to drive a short distance as air naturally passing through the radiator will help to cool the engine, but traffic stops will decrease this ability.
