Tools You Will Likely Need:
* Socket set with ratchet and extensions: To loosen and tighten the alternator mounting bolts (if necessary).
* Wrench (or possibly a socket): To loosen the tensioner pulley. The size will depend on your vehicle.
* New alternator belt: Make sure you get the correct size and type for your Falcon.
* Gloves: To protect your hands.
* Jack and jack stands (optional but recommended): For easier access and safety. If you lift your car, always support it properly on jack stands. Never work under a car supported only by a jack.
* Safety glasses: To protect your eyes from debris.
General Steps (Adapt to your specific Falcon model):
1. Safety First: Disconnect the negative battery terminal to prevent electrical shock.
2. Locate the Alternator and Belt: The alternator is usually located on the side of the engine, and the belt wraps around it and other pulleys (crankshaft, power steering pump, etc.).
3. Identify the Belt Tensioner: This is a pulley with a mechanism to adjust belt tension. It might be spring-loaded or have a bolt to adjust it.
4. Loosen the Tensioner: This is the crucial step. This is where the procedure differs greatly between Falcon models. You'll need to use a wrench (or possibly a socket) to turn the tensioner pulley, relieving tension on the alternator belt. Consult your repair manual for the exact location and method of loosening the tensioner. Some have a bolt you loosen; others have a lever you move.
5. Remove the Old Belt: Once the tension is released, carefully slip the old belt off the pulleys.
6. Install the New Belt: Route the new belt around the pulleys in the same path as the old belt. Make sure it's seated correctly on all pulleys.
7. Tighten the Tensioner: Release the tensioner mechanism (turn the bolt or lever back to its original position). The belt should now be snug.
8. Check Belt Tension: You should be able to push on the belt midway between pulleys with your thumb. There should be a small amount of give, but it shouldn't be loose or floppy. Again, your repair manual will likely have specifications.
9. Reconnect the Battery Terminal: Reconnect the negative battery terminal.
10. Test: Start the engine and check for any squealing or other noises from the belt. If you hear squealing, the belt may be too loose or improperly aligned. If the problem persists, double-check your work or consult a mechanic.
Important Considerations:
* Consult your repair manual: This is absolutely crucial. The exact location and method for accessing and adjusting the belt tensioner will vary significantly depending on your specific Ford Falcon model and year.
* Safety: Always disconnect the negative battery terminal before working on the electrical system. Use jack stands if you lift the car. Wear safety glasses.
* Belt Routing: Pay close attention to how the old belt is routed. Incorrect routing can damage the belt and other components.
If you are not comfortable performing this repair yourself, it's always best to take your vehicle to a qualified mechanic. Attempting this repair without the proper knowledge and tools could result in damage to your vehicle or injury to yourself.
