Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

1. Check Battery Condition
   • If the battery voltage is low, recharge it or replace it with a new one.
   • Ensure the new battery is compatible (typically a Group 51R or 51).
2. Clean Terminals
   • Remove battery terminals (positive first, then negative).
   • Clean terminals and battery posts with a wire brush and a mixture of baking soda and water to remove corrosion.
   • Dry and reconnect terminals, ensuring a tight fit.

3. Starter Motor Inspection

1. Access Starter Motor
   • Remove any components blocking access to the starter (e.g., air intake duct).
   • Locate the starter motor (usually near the transmission).
2. Inspect Connections
   • Ensure the electrical connections to the starter are tight and free of corrosion.
   • Check the starter relay and fuse in the fuse box for proper function.

4. Starter Replacement (if necessary)

1. Remove Starter Motor
   • Disconnect the wiring harness and the battery cable from the starter (negative first).
   • Unbolt the starter motor from the engine block using a socket set.
2. Install New Starter
   • Position the new starter in place and bolt it down with manufacturer-specified torque.
   • Reconnect the wiring harness and battery cable.
