Here's a general outline; specific steps may vary slightly depending on the year of your Mystique. Always consult a repair manual specific to your vehicle's year and engine for precise instructions and torque specifications. A Haynes or Chilton manual is a good investment.
Tools You'll Likely Need:
* Socket wrench set: Including both metric and SAE sizes, you'll need various sizes.
* Ratchet and extensions: To reach hard-to-access bolts.
* Wrench set: For various nuts and bolts.
* Jack and jack stands: Essential for safe working conditions.
* Wheel chocks: To secure the vehicle.
* Penetrating oil (PB Blaster or similar): To help loosen rusted bolts.
* New starter motor: Make sure you get the correct one for your vehicle's engine.
* Wire brush: To clean battery terminals and starter connections.
* Gloves and safety glasses: Protect yourself.
General Steps (Consult your repair manual for specifics):
1. Disconnect the battery: Remove the negative (-) cable first, then the positive (+).
2. Raise and secure the vehicle: Use a jack and jack stands to safely lift the front of the vehicle. Always use wheel chocks on the rear wheels.
3. Access the starter: The starter is typically located on the bottom of the engine, near the transmission bellhousing. Access may require removing some components such as the air intake, some engine shrouds, or even possibly the lower engine splash shield to get a clear view and access. Your repair manual will guide you on this.
4. Disconnect the electrical connections: Carefully disconnect the large positive and small wire cables from the starter using a wrench. Take pictures or make notes of the connections before disconnecting to ensure proper reassembly.
5. Remove the starter bolts: Usually, there are two or three bolts holding the starter in place. Penetrating oil may be necessary to loosen them. Use the appropriate sockets and ratchet to carefully remove the bolts.
6. Remove the starter: Once the bolts are removed, gently remove the starter. It might be a bit tight due to its position. Wiggling it gently may help.
7. Install the new starter: Install the new starter in the reverse order of removal. Ensure it is correctly seated.
8. Reconnect the electrical connections: Reconnect the wires to the new starter, making sure they are secure.
9. Reinstall the starter bolts: Tighten the starter bolts to the manufacturer's specified torque (found in your repair manual).
10. Lower the vehicle: Carefully lower the vehicle from the jack stands.
11. Reconnect the battery: Reconnect the positive (+) cable, then the negative (-) cable.
12. Test the starter: Try starting the engine to make sure the new starter is working correctly.
Important Considerations:
* Rust and Corrosion: Bolts may be seized due to rust. Use penetrating oil liberally and allow sufficient time to work before attempting removal.
* Torque Specifications: Always tighten bolts to the correct torque specification to prevent damage.
* Wiring: Pay close attention to the wiring connections; incorrect connections can damage the starter or other components.
This is a simplified overview. Refer to a repair manual specific to your vehicle's year and engine for detailed instructions and diagrams. Attempting this repair without proper knowledge and tools can lead to injury or further damage to your vehicle. If you are uncomfortable performing this repair yourself, it's best to take it to a qualified mechanic.
