Here's a general procedure. Note: Specifics may vary slightly depending on the engine (3.1L V6 or 3.4L V6). Consult a repair manual specific to your Lumina's year and engine for detailed diagrams and torque specifications. A Haynes or Chilton manual is a great investment for this type of work.
Tools you'll likely need:
* Socket wrench set (metric)
* Ratchet
* Extensions
* Possibly a universal joint for better access
* Possibly a breaker bar for stubborn bolts
* Wire brush (to clean battery terminals and starter connections)
* Penetrating oil (like PB Blaster)
Steps:
1. Disconnect the Battery: Disconnect the negative (-) battery cable first.
2. Access the Starter: The starter is typically located on the driver's side of the engine, towards the bottom. Access will be tight. You may need to remove some components to get a clear shot. This might include:
* Air intake components: Loosen clamps and move the air intake tubing out of the way.
* Exhaust components: Depending on the exact placement, you may need to loosen or remove some exhaust heat shields.
* Other components: Other engine components like wiring harnesses or brackets may need to be carefully moved aside.
3. Locate the Starter Bolts: The starter will be held in place by typically two bolts. They are usually 13mm or 14mm.
4. Loosen the Bolts: Spray penetrating oil on the bolts beforehand to help loosen them. Use a socket wrench and ratchet to carefully loosen and remove the bolts. One bolt might be easier to reach than the other.
5. Disconnect the Electrical Connections: Once the bolts are removed, there will be at least one large cable connected to the starter (and maybe a smaller one). Use a wrench to loosen these connections. They are usually a nut and bolt or a clamp.
6. Remove the Starter: Carefully remove the starter from its position. It might be a bit snug, so gently wiggle it free.
7. Clean the Connections: Use a wire brush to clean the battery terminals and the starter connection points. This ensures good electrical contact when you reinstall the starter.
8. Installation: Installation is the reverse of removal. Be sure to tighten all bolts to the proper torque specification (consult your repair manual). Reconnect the battery cable LAST.
Important Considerations:
* Safety First: Working under a car can be dangerous. Use jack stands, not just a jack, to support the vehicle. Wear safety glasses.
* Take Pictures: Before disconnecting anything, take pictures of the connections and their placement. This will be invaluable when reinstalling everything.
* Repair Manual: A repair manual is highly recommended. It will provide detailed instructions and diagrams specific to your vehicle.
* Professional Help: If you're uncomfortable performing this task yourself, take your vehicle to a qualified mechanic. It's better to pay for professional help than risk damaging your vehicle.
This is a general guideline. Always consult a repair manual specific to your 1995 Chevrolet Lumina for accurate instructions and safety precautions. Remember, working on your car involves risks, and proceeding with caution is essential.
