Tools You'll Need:
* New serpentine belt: Make sure you get the correct size and type for your 2000 Mustang V6.
* Socket wrench set: You'll likely need various sizes, including those for the tensioner pulley.
* Ratchet and extensions: To reach difficult areas.
* Wrench(es): Possibly for holding the tensioner pulley in place. A combination wrench or open-ended wrench might be necessary, depending on the tensioner design.
* Gloves: To protect your hands.
* Jack and jack stands (highly recommended): Working under a car supported only by a jack is dangerous.
* Wheel chocks: To secure the car while it's jacked up.
Steps:
1. Safety First: Park the car on a level surface, engage the parking brake firmly, and use wheel chocks. Jack up the front of the car and securely support it on jack stands.
2. Locate the Serpentine Belt and Tensioner: The serpentine belt runs around several pulleys, including the alternator, power steering pump, and water pump. Identify the belt tensioner pulley – it's usually a pulley with a pivoting arm or a mechanism to adjust tension.
3. Release Belt Tension: This is the most crucial and often the most difficult step. The method varies slightly depending on your Mustang's specific tensioner:
* Spring-loaded tensioner: You'll usually need a wrench (often a 15mm or similar size; check your owner's manual) to turn a bolt or lever on the tensioner. Turning this will release the tension on the belt, allowing you to slip the belt off the pulleys. *You might need to use a pry bar or other tool to leverage the tensioner arm while holding the bolt or lever.* This is where an extra set of hands can be helpful.
* Automatic tensioner: Some models have an automatic tensioner. Consult your repair manual for the proper procedure as this can vary. It might involve using a special tool to bypass or compress the automatic tensioner mechanism to release the tension.
4. Remove the Old Belt: Once the tension is released, carefully work the belt off each pulley. Start with the loosest pulley and work your way around.
5. Install the New Belt: Route the new belt around the pulleys in the same order as the old belt. This is the reverse of the removal process. Ensure the belt sits correctly in all pulley grooves.
6. Release Tensioner: Once the belt is around all the pulleys, release the tensioner (or allow the automatic tensioner to return to its normal position). The belt should now have proper tension.
7. Check Belt Alignment: Visually inspect the belt to ensure it's tracking correctly on all pulleys and isn't rubbing against any components.
8. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
9. Test Run the Engine: Start the engine and listen for any unusual noises (squeaking, squealing) that might indicate a problem with the belt alignment or tension. Check for leaks from the coolant system or power steering system as well.
Important Considerations:
* Repair Manual: A repair manual specific to your 2000 Ford Mustang V6 is invaluable. It will provide detailed diagrams, torque specifications, and step-by-step instructions.
* Safety: Working under a vehicle is inherently dangerous. Always use jack stands, and never rely solely on a jack to support the car's weight.
* Proper Tension: The belt must have the correct tension. Too loose, and it will slip and squeal. Too tight, and it will put undue stress on the pulleys and bearings. Your repair manual will provide guidance on this.
If you're not comfortable performing this task yourself, it's best to take your Mustang to a qualified mechanic. Replacing a serpentine belt incorrectly can lead to more significant and expensive problems.
