- Locate the starter motor: The starter motor is typically located on the engine block, near the transmission.
- Remove the electrical connections: Disconnect the wires attached to the starter solenoid.
- Remove the mounting bolts: Unscrew the bolts that secure the starter motor to the engine block.
- Install the new starter motor: Position the new starter motor and tighten the mounting bolts.
- Reconnect the electrical connections: Attach the wires to the starter solenoid.
- Reconnect the battery: Reconnect the negative battery terminal last.
