Haynes Tech Tips - Starter Replacement
The starter motor is frequently blamed for starting problems. More often, starting problems are related to the battery, alternator, or loose or corroded electrical connections. Before you decide to replace your starter, be sure you have the starting and charging systems thoroughly checked.
Caution
Disconnecting the battery is a necessary part of this procedure. Computers in some vehicles must “re-learn” certain operating data after the battery has been disconnected. On these vehicles, specific procedures must be followed to ensure normal operation after the battery is re-connected. See your service manual for details on your particular vehicle.
- Purchase a service manual for your vehicle. It contains essential information for getting the job done safely and correctly the first time.
- Disconnect the cable from the negative terminal of the battery (see Caution above).
- Locate the starter. Sometimes it can be accessed from under the hood, but usually access is from underneath the engine compartment. If necessary, raise the vehicle and support it securely on jackstands.
- In some cases, you must remove components such as engine covers or exhaust pipes before the starter can be removed. See your service manual for details.
- Disconnect the electrical connections at the starter (see illustration).
- Support the starter and unscrew the mounting bolts (see illustration). Remove the starter from the vehicle.
- Installation is the reverse of removal. Be sure to follow all procedures in your service manual regarding battery re-connection.
Starters usually have two electrical connections – a small one (A) and a large one (B)
If necessary, remove the dust cover bolt and dust cover (1), then remove the starter mounting bolts (2) (typical)
