Tools and Materials Needed:
- Replacement Drive Belt (Matched to your Focus Model)
- Socket and Ratchet Set
- Wrench
- Flat-Head Screwdriver
- Safety Goggles
Step-by-Step Guide:
1. Safety First:
- Wear safety goggles to protect your eyes.
- Ensure the car is parked on a flat surface, the parking brake is engaged, and the engine is off and completely cool.
2. Locate the Belt:
- Open the hood of your Focus and locate the serpentine belt. It's usually made of rubber and runs around various pulleys on the front of the engine.
3. Release Tension:
- Find the belt tensioner, which is usually a spring-loaded component near the belt. Using a wrench, turn the tensioner clockwise to release the tension on the belt.
4. Remove Old Belt:
- Once the tension is released, you can loosen the bolt securing the belt to the alternator or power steering pump. These bolts vary depending on your Focus trim and engine.
- With the tensioner still released and the bolt loosened, slide the old belt off its path.
5. Install New Belt:
- Place the new belt onto the path around all the pulleys. Make sure it's aligned properly and follows the original belt's route.
6. Reapply Tension:
- Once the new belt is in place, use the wrench to turn the tensioner counterclockwise to apply tension to the belt.
- Tighten the bolt securing the belt to the alternator or power steering pump.
7. Double-Check:
- Manually check that the belt is properly positioned and doesn't have any slack or misalignment.
8. Test the Belt:
- Start the engine and let it run for a few minutes. Listen for any unusual noises or vibrations that could indicate an incorrect installation.
9. Adjust Tension if Needed:
- If the belt still seems too loose or noisy, slightly adjust the tensioner again until the belt is properly tensioned.
10. Close the Hood:
- Once you're satisfied that the new belt is installed correctly and functioning smoothly, close the hood of your Focus.
Remember, if you're not confident in performing this task, it's best to seek help from a qualified mechanic. Improper installation of the drive belt can lead to engine issues and safety risks.
