Tools You'll Need:
* Socket wrench set (metric): You'll need various sizes, likely including 13mm, 15mm, and possibly others.
* Ratchet and extensions: To reach the starter bolts.
* Wrench(es): Possibly for holding things in place while you loosen bolts.
* Jack and jack stands: Essential for safe working conditions.
* Wheel chocks: For extra safety.
* Pry bar (optional): Might be helpful for freeing stubborn bolts.
* Wire brush: To clean the battery terminals and starter connections.
* New starter: Make sure you get the correct one for your 1987 Chevy 305 V8.
* Penetrating oil (like PB Blaster): Helpful for loosening rusted or stuck bolts.
Procedure:
1. Safety First: Disconnect the negative battery cable. Chock the wheels and securely jack up the vehicle, supporting it on jack stands. Never work under a vehicle supported only by a jack.
2. Locate the Starter: The starter is usually located on the passenger side of the engine block, near the bell housing (where the engine connects to the transmission).
3. Access the Starter: You might need to remove some components to get better access. This varies depending on the specific model and any aftermarket modifications. Common things you may need to remove include:
* Air cleaner assembly: Often needs to be moved or removed entirely.
* Wiring harnesses: Carefully move these out of the way. Take pictures before disconnecting anything.
* Exhaust components: Sometimes parts of the exhaust system may need to be loosened or removed.
4. Disconnect the Electrical Connections: There will be at least two large cables connected to the starter: the positive (+) and the negative (-). Carefully loosen and remove these. A wire brush can help clean the terminals before reconnection.
5. Remove the Starter Bolts: Typically, there are two or three bolts securing the starter to the engine block. Spray penetrating oil on them beforehand if they seem stuck. Use your sockets and ratchet to remove the bolts.
6. Remove the Starter: Once the bolts are out, the starter should be relatively free. It might be a bit tight due to years of grime and mounting pressure. Use a pry bar carefully if needed, but be gentle to avoid damaging the starter or the engine block.
7. Installation:
* Install the new starter in the reverse order of removal.
* Ensure the starter is properly seated.
* Tighten the bolts to the manufacturer's specified torque.
* Reconnect the electrical cables securely.
8. Reconnect the Battery and Test: Reconnect the negative battery cable. Try to start the engine. If it doesn't start, double-check all connections and ensure the new starter is properly installed.
Important Considerations:
* Year and Model Variations: The exact location and accessibility of the starter might slightly vary between different 1987 Chevy 305 V8 models (e.g., pickup truck, Camaro, etc.). Consult a repair manual specific to your vehicle.
* Torque Specifications: Use a torque wrench to tighten the starter bolts to the manufacturer's recommended specification. Over-tightening can damage the starter or engine block. Under-tightening can cause the starter to come loose.
* Repair Manual: A factory service manual or a Haynes/Chilton manual specific to your 1987 Chevy 305 V8 is highly recommended. It will provide detailed diagrams, torque specifications, and other crucial information.
This is a general guide. If you're not comfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic. Improper installation can lead to further damage or injury.
