Tools you'll likely need:
* Socket wrench set: Including metric sockets (sizes will vary depending on your vehicle, check your repair manual).
* Ratchet: A comfortable ratchet is essential.
* Extensions: To reach the starter bolts.
* Wrench (possibly): May be needed for some bolts, depending on accessibility.
* Jack and jack stands: Essential for safe working conditions. Never work under a car supported only by a jack.
* Wheel chocks: To secure the vehicle.
* Torque wrench: For tightening bolts to the manufacturer's specifications (found in your repair manual).
* Wire brush: To clean battery terminals and starter connections.
* New starter motor: Make sure to get the correct one for your Alero's engine.
* Gloves and safety glasses: Always protect yourself.
* Penetrating oil (PB Blaster or similar): To help loosen rusted bolts.
Steps (General Outline – Consult your repair manual for specifics):
1. Disconnect the battery: Disconnect the negative (-) battery cable first, then the positive (+).
2. Prepare the vehicle: Jack up the vehicle and securely place it on jack stands. Engage the parking brake and use wheel chocks for added safety.
3. Access the starter: The starter is typically located on the engine block, near the transmission bell housing. Access may require removing some components, such as the air intake duct, some heat shields, or parts of the exhaust system. Your repair manual will show you exactly what needs to be removed.
4. Disconnect the starter wiring: There will be at least two wires connected to the starter. Carefully disconnect them, noting their positions so you can reconnect them correctly later. Take photos if needed. Use a wire brush to clean the connections.
5. Remove the starter mounting bolts: These bolts are usually located on the top and bottom of the starter. Apply penetrating oil if they're difficult to loosen. Carefully remove the bolts.
6. Remove the starter: Once the bolts are removed, carefully remove the starter from its mounting location. It might be slightly tight.
7. Install the new starter: Install the new starter, aligning it with the mounting holes.
8. Reconnect the starter wiring: Reconnect the starter wiring, ensuring a secure connection.
9. Secure the starter: Tighten the starter mounting bolts to the manufacturer's specified torque. Refer to your repair manual for the correct torque specifications.
10. Reconnect the battery: Reconnect the positive (+) battery cable first, then the negative (-) cable.
11. Lower the vehicle: Carefully lower the vehicle from the jack stands.
12. Test the starter: Start the engine to ensure the new starter is working correctly.
Important Considerations:
* Repair Manual: This is absolutely crucial. A general guide like this cannot replace the detailed, vehicle-specific instructions in a repair manual.
* Safety: Always prioritize safety. Work in a well-lit area, use jack stands correctly, and disconnect the battery.
* Bolts: Bolts can be stubborn, especially if they're rusted. Use penetrating oil and avoid stripping the bolt heads.
* Torque Specifications: Incorrect torque can damage the starter or its mounting points. Always use a torque wrench and follow the specifications in your repair manual.
If you are not comfortable performing this repair yourself, take your car to a qualified mechanic. It is far safer and likely cheaper than damaging your vehicle trying to perform this repair without the proper knowledge and tools.
