Solution

1. Preparation

Tools Required:
- Socket set
- Torque wrench
- Wrench set
- Screwdrivers
- Multimeter
- Jack and jack stands
Disconnect the negative battery terminal to prevent electrical shock.
Raise the vehicle using a jack and secure it on jack stands.

2. Remove the Engine Under Cover

Locate the engine under cover and remove any screws or clips securing it.
Gently lower the cover and set it aside to access the starter.

3. Remove the Starter

Locate the starter on the engine (usually near the transmission).
Disconnect the electrical connectors from the starter:
- Remove the nut securing the battery cable to the starter terminal.
- Disconnect the smaller wire from the solenoid.
Remove the mounting bolts securing the starter to the engine block (typically 2-3 bolts).
Carefully pull the starter out of its mounting location.

4. Install the New Starter

Position the new starter into place, aligning it with the mounting holes.
Secure the starter with the mounting bolts. Torque the bolts to the manufacturer's specifications (typically around 10-15 ft-lbs).
Reconnect the electrical connectors:
- Attach the smaller wire to the solenoid.
- Secure the battery cable with the nut.

5. Reassemble

Reinstall the engine under cover and secure it with screws or clips.
Lower the vehicle from the jack stands.
Reconnect the negative battery terminal.
