Here's a general outline. Specific procedures and locations may vary slightly depending on the engine (V6 or V8). Consult a repair manual specific to your year and engine for detailed diagrams and torque specifications. A Haynes or Chilton manual for your vehicle is highly recommended.
Tools You'll Likely Need:
* Socket wrench set (metric)
* Ratchet and extensions
* Wrenches (metric)
* Pliers
* Jack and jack stands (essential for safety)
* Wheel chocks
* Wire brush
* Battery terminal cleaner
* New starter motor
* Penetrating oil (like PB Blaster)
General Steps:
1. Preparation: Park on a level surface, engage the parking brake, and chock the wheels. Disconnect the negative battery cable.
2. Access the Starter: The starter is usually located on the engine block, near the transmission bell housing. Access may be difficult and require removing some components depending on the engine. This often involves:
* Removing parts: You might need to remove parts like the air cleaner assembly, some engine accessories (potentially the power steering pump or alternator depending on the specific model and location of the starter), or even parts of the exhaust system to get a clear shot at the starter. Again, a repair manual will be invaluable here.
3. Disconnect the Starter Wiring: This is crucial and usually involves:
* Large positive cable: This is a thick cable connecting the starter to the battery's positive terminal (or a nearby junction). Carefully disconnect this.
* Small wire: This smaller wire usually controls the solenoid within the starter. Carefully disconnect it.
4. Remove the Starter Mounting Bolts: The starter is typically held in place by two or three bolts. Penetrating oil applied beforehand will help loosen rusted bolts. Carefully remove these bolts, and keep track of their locations.
5. Remove the Starter: Once the bolts are removed, the starter should come free. It might be a little tight due to the weight and possible corrosion. Gently wiggle it free.
6. Install the New Starter: Carefully install the new starter, ensuring it's correctly seated. Reinstall the mounting bolts, tightening them to the manufacturer's specifications (consult your repair manual).
7. Reconnect the Wiring: Carefully reconnect the small wire and then the large positive cable to the new starter. Make sure all connections are secure.
8. Reinstall Removed Components: Put back all the parts you removed earlier (exhaust, engine accessories, etc.) in the reverse order of removal.
9. Reconnect the Battery: Reconnect the negative battery cable.
10. Test the Starter: Try starting the engine. If it doesn't start, double-check all connections and the tightness of the mounting bolts.
Important Considerations:
* Safety: Working under a car is dangerous. Use jack stands, not just a jack, to support the vehicle. Never work under a car supported only by a jack.
* Repair Manual: A repair manual is your best friend for this job. It provides detailed instructions, diagrams, torque specifications, and component locations specific to your vehicle.
* Professional Help: If you're uncomfortable performing this repair yourself, take your car to a qualified mechanic.
This is a general guide. Failure to follow the correct procedures for your specific vehicle could damage your car or injure you. Always consult a repair manual specific to your 1987-88 Oldsmobile Delta 88 before attempting this repair.
