Frequently Asked Questions

Can I drive with P1480 error code?
You should avoid driving with P1480 as it indicates cooling fan problems that can lead to engine overheating. If you must drive, keep trips short, monitor the temperature gauge closely, and pull over immediately if the engine starts to overheat.

What causes cooling fan motor failure in Subaru?
Common causes include normal wear and tear, debris blocking the fan, electrical issues like blown fuses or bad relays, corroded connections, or bearing failure in the motor itself. Age and high mileage are contributing factors.
Will P1480 cause my Subaru to overheat?
Yes, P1480 can definitely cause overheating, especially in stop-and-go traffic or hot weather. The cooling fan is essential for maintaining proper engine temperature when the vehicle isn't moving fast enough for natural airflow.
How do I know if my cooling fan motor is bad?
Signs of a bad cooling fan motor include the fan not running when the engine is warm, unusual noises from the fan area, visible damage to fan blades, or the P1480 error code. You can also test the motor directly with 12V power to confirm if it's working.
