1. Preparation:
* Gather Tools: You'll need a socket wrench set (including extensions), a ratchet, possibly a breaker bar, a torque wrench, a wire brush, and possibly a puller for the old starter. Safety glasses are also essential.
* Identify the Starter: Locate the starter motor on the engine block, typically near the bellhousing (the area where the engine connects to the transmission).
* Consult a Repair Manual: A Haynes or Chilton manual specific to your truck's year and model is invaluable. It will show you the exact location of bolts, wiring, and torque specifications.
2. Removing the Old Starter:
* Disconnect the Battery Cable: Disconnect the negative (-) battery cable.
* Disconnect Wiring: Disconnect the two large battery cables from the starter solenoid (the smaller electrical component on the starter). One is usually a thick positive (+) cable and the other is a smaller wire controlling the solenoid. Take pictures or make notes of the connections to ensure you reconnect them correctly.
* Remove Starter Bolts: Use the appropriate sockets and wrench to remove the bolts holding the starter to the engine block. These are usually two bolts. They might be difficult to access, so patience and the right tools are important. A breaker bar might be necessary if the bolts are rusted or stuck.
* Remove the Starter: Once the bolts are removed, carefully remove the starter from its mounting location. A slight wiggle or tap might be necessary.
3. Installing the New Starter:
* Clean Mounting Surfaces: Clean any dirt, rust, or debris from both the starter and the engine block mounting surfaces using a wire brush.
* Install the New Starter: Carefully align the new starter with its mounting holes on the engine block.
* Tighten Bolts: Secure the starter using the bolts. Do not overtighten; use a torque wrench and refer to your repair manual for the correct torque specifications.
* Reconnect Wiring: Reconnect the large battery cables and the smaller control wire to the starter solenoid, making sure they are securely fastened. Double-check that the positive (+) and negative (-) are in the correct locations.
* Reconnect Battery Cable: Reconnect the negative (-) battery cable.
4. Testing:
* Attempt to Start the Engine: Try starting the engine. If it doesn't start, double-check all connections, ensuring that the wiring is correctly attached and the starter bolts are tight. If the problem persists, there might be an additional electrical issue.
Important Considerations:
* Year-Specific Differences: The exact procedure can vary slightly depending on the year and model of your Chevy 350 truck. Always consult a repair manual specific to your vehicle.
* Safety: Disconnect the battery's negative terminal before starting any work on the electrical system. Never work on a vehicle with the engine running.
* Professional Help: If you are uncomfortable performing this repair yourself, it's always best to seek professional help from a qualified mechanic.
This is a general guide; a detailed repair manual tailored to your specific truck model is essential for successful starter replacement. Using the wrong torque settings can damage the starter or engine block.
