Your vehicle’s engine is constantly burning fuel and gets hot. The car’s cooling system is responsible for carrying heat away to the outside air. The radiator fan motor powers the cooling fan, which keeps the engine from overheating. The fan is located in the engine compartment, at the front or rear of the radiator. The fan cools the coolant as it passes through the radiator. The coolant flows through the entire engine and is responsible for absorbing the extra heat and thereby preventing the engine from overheating. The fan blows the air from the outside and passes it through the radiator. If the cooling fan motor and the fan stop working, the coolant will remain hot and cause the engine to overheat.
Scan the computer system for any diagnostic trouble codes. Test fuses and relays. Test for power and ground going to the fan. Remove and replace the radiator fan motor. Check for proper operation of fan.
If a defective radiator fan motor is left unchecked, the car will overheat and effectively become undriveable.
