Here's a general guide. This is not a substitute for a proper repair manual specific to your 1992 Mustang. Consult a Haynes or Chilton manual for detailed instructions and diagrams specific to your engine (e.g., 2.3L, 3.8L, 5.0L). Variations exist depending on the engine and transmission.
Tools You'll Likely Need:
* Socket wrench set: Including metric and possibly SAE sockets.
* Ratchet: A breaker bar might be helpful for stubborn bolts.
* Extension(s): To reach difficult-to-access bolts.
* Wrench(es): For various nuts and bolts.
* Jack and jack stands: To safely lift the vehicle.
* Wheel chocks: To secure the vehicle.
* Torque wrench: To tighten bolts to the manufacturer's specifications (consult your repair manual).
* Wire brush: To clean battery terminals and starter connections.
* Penetrating oil (PB Blaster or similar): To loosen rusted bolts.
* New starter motor: Make sure you get the correct one for your Mustang's engine.
General Steps (Consult your repair manual for specifics):
1. Disconnect the battery negative terminal. This is crucial to prevent electrical shocks and short circuits.
2. Raise and secure the vehicle: Use a jack and jack stands to safely lift the front of the car. Always place wheel chocks on the rear wheels.
3. Locate the starter motor: It's usually on the engine block, near the transmission bell housing. Its location will vary slightly depending on the engine.
4. Disconnect the electrical connections: There will be at least two large cables connected to the starter – one positive (+) and one smaller negative (-). Use a wrench to carefully loosen and remove the nuts securing these cables. Take note of their position for reassembly.
5. Remove the starter mounting bolts: These are usually 2-3 bolts securing the starter to the engine block or transmission. You might need to use penetrating oil to loosen rusted bolts. Allow sufficient time for the oil to penetrate.
6. Remove the starter motor: Once the bolts are loosened, carefully remove the starter. It might be a bit heavy, so be prepared to support its weight.
7. Install the new starter motor: Carefully align the new starter with the mounting holes and install the bolts. Tighten them securely but don't overtighten.
8. Reconnect the electrical connections: Attach the positive (+) and negative (-) cables to the new starter, ensuring a secure connection.
9. Lower the vehicle: Carefully lower the car from the jack stands.
10. Reconnect the battery negative terminal: Once everything is secure, reconnect the negative battery terminal.
11. Test the starter: Turn the ignition key to the start position. The engine should crank and start.
Important Considerations:
* Rust and corrosion: Bolts and connections can be severely corroded, especially on older vehicles. Use penetrating oil liberally and allow ample time to work. A wire brush can help clean corroded areas.
* Accessibility: The starter might be in a tight spot, requiring some maneuvering of tools and possibly some removal of other components to gain better access. Your repair manual will guide you.
* Torque specifications: Over-tightening bolts can damage the starter or its mounting points. Always use a torque wrench and consult your repair manual for the correct specifications.
This is a simplified overview. Always refer to a repair manual specific to your 1992 Ford Mustang for detailed instructions, diagrams, and torque specifications. If you are not comfortable performing this repair yourself, take your car to a qualified mechanic.
