What to know about the Cooling/Radiator Fan Motor:
Your vehicle’s engine is regularly burning fuel and gets hot. The car’s cooling system is in charge of carrying heat away to the outside air. The cooling fan motor powers the cooling fan, which preserves the engine from overheating. The fan is positioned in the engine section, 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 in charge of absorbing the extra heat and thereby stopping 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.
Facts to Note:
When the cooling fan motor is changed, the cooling fan blade should also be examined.
Anytime that upkeep is done on the cooling system, the fan motor should be examined.
How to Fix:
Scan the computer system for any diagnostic trouble codes.
Test fuses and relays.
Test for power and ground going to the fan.
Take out and change the radiator fan motor.
Check for proper operation of fan.
The cooling fan motor is an electrical motor that exist in a high temperature environment. At some point over time, it may fail. If you notice that the engine is overheating (see the temperature gauge in the dashboard), and you do not hear the fan(s) working get the cooling system inspected immediately.
Your mechanic should check the coolant and fill, if needed.
Keep an eye on the service maintenance schedule provided by the manufacturer to replace the coolant. It is a good practice to change the coolant every 25,000 to 40,000 miles.
Common symptoms indicating you may need to change the Cooling/Radiator Fan Motor:
Check Engine light may be on.
Cooling Fan fuse may be blown.
Importance of this service:
If a faulty cooling/radiator fan motor is left unchecked, the car will overheat and effectively become non drivable.
