The engine cooling fan is designed to pass air through the radiator when the vehicle is running at a low speed or parking. This airflow uses a radiator as a conductor to remove heat from the coolant produced by the engine. The engine cooling fan performs temperature control only when needed. All engines have a preferred operating temperature and require warm-up to operate at maximum efficiency. Even for a short time, the temperature is still higher than the normal level, which may cause the internal parts of the engine to malfunction.
After the engine is turned off, the sound of the fan is sometimes heard. This is normal and can reduce the engine temperature to an acceptable level. Usually, the auto electric fan will start shortly after turning on the auto air conditioner. This is done to dissipate the excess heat generated in the condenser when the air conditioner is running.
The engine cooling fan only performs temperature control when needed. All engines have a preferred operating temperature, which requires a warm-up period to achieve maximum efficiency. Higher than normal temperature will cause the internal parts of the engine to malfunction. When the radiator cooling fan fails, it will cause the engine coolant to retain heat, forcing the engine to overheat and eventually leading to overheating.
