Replacing a Starter

The starter is a small, high torque electric motor that mechanically engages and turns the engine flywheel causing the engine to crank and start.

Safety First

Disconnect the battery. You only need to remove the negative cable. This is a good move any time you're working on the car. NOTE: Many vehicles need to be raised up to reach the starter. On others, obtaining starter access can be difficult. Check your vehicle repair manual for location and replacement details. Always use safety stands and wheel chocks along with protective eye wear.

Remove the Wiring

Remove the wiring and positive battery cable from the starter solenoid.

Remove the Starter and Bolts

Remove the starter retaining bolts. Remove the starter. NOTE: AutoZone will test your starter for free. This will help to verify you are working on the correct problem of the car.

Compare to Verify

Compare the new starter to verify it will fit. Note: Some replacement starters do not appear identical but will have the same fit, form and function as the original (old) unit. Refer to product or installation bulletins packaged with the starter

Transfer Heat Shield

Transfer any heat shield and/or brackets (if equipped) to the replacement starter.

Replace with New Starter
