This article applies to the Ford F-150 truck (2004-2014) and F-250 Super Duty (2005-2014).

For a car engine to operate at the right temperature, it needs the radiator to get rid of excess heat. The radiator has a fan which aerates the engine to prevent it from overheating. The fan in the Ford F-150 or Super Duty is between the engine and the radiator.

Material and Tools Needed

  • Screwdriver
  • Wrench
  • Ratchet set
  • New fan

Step 1 - Remove radiator cover

To prevent possible after shocks, disconnect the battery and remove the lead wire connected to the fan's motor. Using a screwdriver, remove the fasteners holding the plastic radiator cover in place. Also, remove air intake boxes to have unfettered access to the radiator fan.

Step 2 - Remove the fan

The radiator fan is mounted on a pulley rotated by the engine belt. Using a wrench, unscrew the bolts that hold the fan into place. Fans are mostly held in place by 4 bolts, two on the top and two on the bottom. Re-connect the lead wire connecting to your fan's motor.

Step 3 - Install the new fan

With the old fan removed, mount the new one and tighten the screws and bolts where the old was positioned. Re-connect your battery and start your truck. Wait for the fan to go on to make sure the process was a success.

Pro Tip

Regular oil checks are critical for ensuring that friction-sensitive components like the cooling system are always well lubricated. A constantly warm engine can signal a leak within the cooling system. A leak is often accompanied by a whistling sound

Because it has less drag than a stock fan, electric fans improve gas mileage and horse power.
