Step 3: Jack Up the Vehicle
Use a floor jack to lift your vehicle and secure it with jack stands. Never work under a car supported only by a jack.
Step 4: Remove Electrical Connections
Carefully remove the wiring harness and main power cable connected to the starter. Mark the cables to ensure correct reinstallation.
Step 5: Unbolt the Old Starter
Use a socket wrench to remove the mounting bolts holding the starter in place. Support the starter as you remove the last bolt to prevent it from falling.
Step 6: Install the New Starter
Position the new starter motor and hand-tighten the bolts first. Once aligned, torque them to the manufacturer’s specifications. Reconnect the electrical connectors and cables securely.
Step 7: Reconnect Battery and Test
Reconnect the negative battery terminal, lower the vehicle, and start the engine. The car should crank smoothly without clicking or grinding noises.
