Tools You'll Likely Need:
* Socket set (metric): Various sizes, including likely a 13mm, 15mm, and possibly larger for the alternator mounting bolts.
* Wrench set (metric): To supplement the sockets, especially for difficult-to-reach nuts or bolts.
* Ratchet: A good quality ratchet will make the job much easier.
* Extension bars: To reach those hard-to-access fasteners.
* Universal joint: For added maneuverability in tight spaces.
* Torque wrench: Crucial for tightening bolts to the correct specification. Improper tightening can damage the alternator or its mounting points.
* Jack and jack stands: Essential for safely working underneath the vehicle. Never work under a vehicle supported only by a jack.
* Wheel chocks: To prevent the vehicle from rolling.
* Battery terminal cleaner: A good idea to clean the battery terminals while you're working in the area.
* New alternator: Make sure to get the correct alternator for your specific vehicle year and engine. The part number should be verified with an auto parts store.
* Gloves and safety glasses: Always wear appropriate safety gear when working on your vehicle.
* Possibly a pulley puller: Depending on the alternator's design, you might need this to remove the pulley.
General Steps (Consult your repair manual for detailed instructions):
1. Disconnect the battery: This is crucial to prevent electrical shocks and damage to electrical components. Disconnect the negative (-) terminal first, then the positive (+) terminal.
2. Access the alternator: This often involves removing some components to get a clear view and reach the alternator's mounting bolts. On the Lincoln LS, this might involve removing the serpentine belt and potentially some other parts obstructing access. Consult your repair manual for the correct procedure.
3. Remove the serpentine belt: Use a serpentine belt tensioner tool to release the tension on the belt and remove it from the alternator and other pulleys.
4. Disconnect electrical connectors: Carefully disconnect the electrical connectors from the alternator. Take note of their location for reassembly.
5. Remove the alternator mounting bolts: These bolts typically hold the alternator to the engine block or a bracket. Loosen them before attempting to remove the alternator.
6. Remove the alternator: Once the bolts are loose, carefully remove the alternator from its mounting location. It may be heavy, so be prepared.
7. Install the new alternator: Reverse the removal process. Ensure the electrical connectors are securely attached and the mounting bolts are tightened to the correct torque specification (consult your repair manual).
8. Reinstall the serpentine belt: Make sure the belt is properly routed around all the pulleys.
9. Reconnect the battery: Connect the positive (+) terminal first, then the negative (-) terminal.
10. Test the alternator: Start the engine and check for proper charging voltage using a multimeter.
Important Considerations:
* Serpentine Belt Routing: Pay close attention to how the serpentine belt is routed. Incorrect routing can damage the belt and other components.
* Torque Specifications: Use a torque wrench to tighten bolts to the manufacturer's specifications. This prevents damage to the alternator and its mounting points.
* Repair Manual: A repair manual specific to your 2000 Lincoln LS is highly recommended. It will provide detailed instructions, diagrams, and torque specifications.
This is a complex repair. If you are not comfortable working on your vehicle, it's best to take it to a qualified mechanic. Attempting this repair without proper knowledge and tools can result in damage to your vehicle or personal injury.
