Essential Tools:
* Socket Wrench Set: A good selection of metric sockets, including a deep well socket for the alternator mounting bolts. You'll likely need 13mm, 15mm, and possibly others depending on the specific model.
* Ratchet: A ratchet handle that fits your sockets. A 3/8" drive ratchet is usually sufficient.
* Wrench Set: Metric wrenches for any difficult-to-reach nuts or bolts. Often used in conjunction with the socket set.
* Extension(s): Socket extensions will be crucial to reach the alternator bolts, especially the rearmost one.
* Breaker Bar (optional but recommended): Some alternator bolts can be very tight. A breaker bar provides extra leverage to loosen stubborn fasteners.
* Pliers: Needle-nose pliers might be helpful for disconnecting electrical connectors.
* Screwdriver(s): Phillips and flathead screwdrivers may be needed to remove any plastic shrouds or covers.
* Jack and Jack Stands (or ramps): For safety, you should always raise the vehicle and securely support it before working underneath.
* Wheel Chocks: Place wheel chocks on the wheels that remain on the ground to prevent accidental movement.
Highly Recommended Tools:
* Socket Set with Wobble Extension: A wobble extension allows for a greater range of motion when working in tight spaces.
* Torque Wrench: To properly tighten the alternator bolts to the manufacturer's specifications after reinstallation, preventing damage and ensuring proper function.
* Gloves: To protect your hands from grease and grime.
* Safety Glasses: To protect your eyes from debris.
Potentially Needed Tools:
* Battery Disconnect Tool: Always disconnect the negative battery terminal first before starting any work on the electrical system.
* Wire Brush: To clean corrosion from battery terminals and alternator connections.
* Electrical Tape: In case any wires or connectors need to be temporarily secured.
* Shop Rags: To clean up grease and oil spills.
Remember to consult your Ford Expedition's repair manual for specific torque specifications and bolt sizes. The exact tools and their sizes might vary slightly depending on the engine and specific alternator configuration. Always prioritize safety and use caution when working under a vehicle.
