What is a cooling/radiator fan motor?
The cooling/ radiator fan is an important part of your vehicle’s cooling system, which keeps your engine at operable temperatures.
The cooling/ radiator fan motor powers the fan blade to dissipate the extra heat absorbed by the coolant passing through the entire engine. The fan can be found in the engine compartment, usually at the front or rear of the radiator. This prevents the engine from getting too hot when it is burning fuel.
A broken cooling/ radiator fan motor will not lower the temperature of the engine, causing it to overheat. While there is no immediate danger, the engine can seize at extreme temperatures, as the piston can weld itself to the cylinder.
When should I replace the cooling/radiator fan motor on my car?
The most common symptoms of a failing cooling/ radiator fan motor include:
Overheating engine: Your cooling/ radiator fan motor is responsible for cooling down your vehicle’s engine. If you notice that the temperature gauge on your dashboard is consistently high, it’s likely due to a faulty cooling/ radiator fan motor.
Improper air conditioner function: If your A/C is blowing hot air and is not cooling down, there may be something wrong with your cooling/ radiator fan motor.
Quiet fans: When your cooling/ radiator fan motor is down, you won’t hear the airflow from the fans. If your vehicle is especially quiet, you should have your cooling/ radiator fan motor inspected.
Check engine light: Your check engine light may be the result of a faulty cooling/ radiator fan motor.
In some cases, your cooling fan fuse may be the culprit for the symptoms listed above. Your mechanic will run a diagnostic test to uncover the true cause of your vehicle’s symptoms.
How often should a cooling/radiator fan motor be replaced?
For nearly all vehicles, there is no replacement schedule for cooling/ radiator fan motors. In fact, most cooling/ radiator fan motors are constructed to last the lifespan of the vehicle.
Keep in mind: While your cooling/ radiator fan motor is made to last, the deterioration of other vehicle components may lead to cooling/ radiator fan motor wear and tear.
Can I replace my cooling/radiator fan motor myself?
If you’re handy with DIY car repairs, you may be able to replace your cooling/ radiator fan motor yourself. However, your cooling fan assembly is slightly intricate and replacing your radiator fan motor requires a meticulous understanding of your vehicle’s interworking components.
Typically, it’s best to let a certified mechanic perform a cooling/ radiator fan motor replacement.
