Tools You'll Need:
* New serpentine belt: Make sure you get the correct size and type for your 1999 Lincoln Town Car. The part number can be found in your owner's manual or at an auto parts store.
* Wrench set: You'll likely need various sizes, including those that fit the belt tensioner pulley.
* Socket set: Possibly needed for some access points.
* Ratchet: To use with the wrenches and sockets.
* Socket extensions: May be necessary to reach tight spots.
* Pliers or a belt tensioner tool: Some tensioners use a special tool; others can be manipulated with pliers. However, using the wrong method can result in damage to the tensioner.
* Jack and jack stands: To safely lift the car. Never work under a car supported only by a jack.
* Gloves: To protect your hands.
* Shop rags or paper towels: To clean up any spilled fluids.
Steps (General - Consult Your Repair Manual for Specifics):
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels. Disconnect the negative battery cable to prevent accidental short circuits.
2. Locate the Belt Tensioner: Identify the belt tensioner pulley. This is a pulley with a mechanism to create tension on the belt. It's usually spring-loaded.
3. Access the Belt: You may need to remove some components (e.g., plastic shrouds or covers) to gain access to the belt and tensioner.
4. Release Tension: This is the most crucial and potentially tricky step. Refer to your repair manual for the exact method. Some tensioners require a special tool, others can be carefully loosened using a wrench or pliers on the appropriate bolt or lever. You may need to carefully pry or leverage the tensioner to relieve enough pressure to remove the belt. Be extremely cautious not to damage the tensioner or surrounding components.
5. Remove the Old Belt: Once the tension is released, carefully work the belt off the pulleys. Note the routing of the belt; you'll need to reinstall it in the same order.
6. Install the New Belt: Carefully route the new belt around the pulleys, following the same path as the old belt. Double-check your routing before tightening.
7. Re-engage Tensioner: Carefully release the tensioner back to its resting position. The belt should now be snug on all pulleys.
8. Check Tension: Manually check that the belt is snug but not overly tight. It should not be easily twisted or moved.
9. Reconnect Battery Cable: Reattach the negative battery cable.
10. Start the Engine: Start the engine and listen for any unusual squealing or noise. If you hear unusual noises, shut off the engine immediately. You may have incorrectly routed the belt.
11. Inspect: Carefully inspect the belt and tensioner for any damage.
Important Considerations:
* Refer to your repair manual: This is not a comprehensive guide. Different vehicles have different belt routing and tensioner mechanisms.
* Torque Specifications: Always tighten bolts to the manufacturer's specified torque. Over-tightening can damage components.
* Professional Help: If you are uncomfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic.
Remember, safety is paramount. If you're unsure about any step, it's always best to seek professional assistance. Improperly installing a serpentine belt can cause serious engine damage.
