Tools You'll Likely Need:
* Jack and jack stands: Essential for safely raising the vehicle.
* Wheel chocks: To prevent the vehicle from rolling.
* Socket wrench set: Various sizes, including metric and possibly SAE depending on your car.
* Ratchet and extensions: To reach tight spots.
* Wrench(es): Possibly open-ended or combination wrenches for certain bolts.
* Torque wrench: Crucial for tightening bolts to the manufacturer's specifications. Incorrect torque can damage components.
* Pry bar or similar tool: Might be needed to help break loose stubborn pulleys.
* Gloves: To protect your hands.
* Safety glasses: To protect your eyes from debris.
* New idler pulley: Make sure you purchase the correct replacement part for your specific Mustang model and engine.
* Shop rags or paper towels: To clean up any spilled fluids.
General Steps (These are *general* and may vary based on the exact location and type of idler pulley):
1. Safety First: Disconnect the negative battery terminal. This prevents accidental shorts and protects electronic components. Park the car on a level surface, engage the parking brake, and use wheel chocks.
2. Raise and Secure the Vehicle: Safely raise the front of the vehicle using a jack and secure it on jack stands.
3. Locate the Idler Pulley: Identify the idler pulley you need to replace. It's typically a small pulley on the serpentine belt system that doesn't directly drive any accessories. Consult a repair manual or online diagram specific to your Mustang's engine to be certain.
4. Remove the Serpentine Belt: This is usually done by loosening the tensioner pulley. The method for doing this varies depending on the engine; some tensioners are spring-loaded, others might require a specific wrench or tool to loosen. Consult a repair manual for your specific model to avoid damage. Once the tension is released, the belt should be easily removable.
5. Remove the Idler Pulley: This usually involves removing one or more bolts securing the pulley to its bracket. Use the appropriate sockets and wrenches. They may be stubborn; use penetrating oil if necessary and avoid damaging surrounding components.
6. Install the New Idler Pulley: Install the new idler pulley, ensuring it's properly seated. Tighten the bolts to the manufacturer's specified torque using your torque wrench.
7. Reinstall the Serpentine Belt: Carefully route the serpentine belt around all the pulleys in the correct order. Again, consult a repair manual or diagram to ensure proper routing.
8. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
9. Reconnect the Battery Terminal: Reconnect the negative battery terminal.
10. Check for Proper Operation: Start the engine and check for any unusual noises or belt slippage. Inspect the belt for proper alignment and tension.
Important Considerations:
* Repair Manual: Highly recommended. A repair manual specific to your 2000 Ford Mustang will provide detailed instructions, diagrams, and torque specifications. This is crucial to avoid damage and ensure proper repair.
* Professional Help: If you are not comfortable performing this repair yourself, it's best to take your Mustang to a qualified mechanic. Improper repair can lead to serious damage to your engine.
* Penetrating Oil: Use penetrating oil to help loosen any seized bolts before attempting to remove them.
This is a general overview. The specific steps and tools required will vary depending on your engine type (V6 or V8). Always consult a repair manual specific to your vehicle before attempting this repair. Safety should be your top priority.
