Here's a general outline. Specifics might vary slightly depending on the exact engine and transmission:
1. Preparation:
* Disconnect the battery: This is crucial for safety. Disconnect the negative (-) terminal first.
* Gather tools: You'll need a socket wrench set (likely 13mm and 15mm sockets), a ratchet, extensions, possibly a breaker bar, and possibly a small pry bar. Gloves are recommended.
2. Accessing the Starter:
* Locate the starter: It's usually on the passenger side of the engine, near the bellhousing (where the engine connects to the transmission). You may need to consult a repair manual or online diagrams for your specific engine to get the precise location.
* Clear access: You may need to remove or loosen some components to gain better access. This could include:
* Air intake components: Disconnect and move aside the air intake system.
* Wiring harnesses: Carefully move aside any electrical harnesses that might be in the way. Don't force anything; gently unclip and relocate them.
* Exhaust components: Depending on the engine and the starter's location, you might need to slightly loosen or remove an exhaust heat shield.
* Note wire and cable positions: Take pictures or make careful notes of how all wires and cables are connected to avoid confusion during reinstallation.
3. Removing the Starter:
* Disconnect the electrical connections: There are usually two large wires (power and solenoid) attached to the starter. Carefully disconnect these using a wrench (likely 13mm). Some might have a retaining clip; gently release them.
* Remove the starter bolts: The starter is typically held in place by two bolts. Locate them and carefully remove them using the appropriate socket and ratchet. You may need an extension and possibly a breaker bar if the bolts are stubborn.
* Remove the starter: Once the bolts are removed, carefully remove the starter from its position. It might be a little snug; gently wiggle it free.
4. Reinstallation (Reverse Order):
* Install the starter in reverse order of removal.
* Ensure the bolts are tightened securely.
* Reconnect the electrical connections, making sure they are secure.
* Reconnect any components you removed to gain access (air intake, etc.).
* Reconnect the battery's negative terminal.
Important Considerations:
* Repair Manual: A repair manual specific to your 2001 Chevy Impala is highly recommended. It will provide detailed diagrams, torque specifications, and troubleshooting guidance. You can find these online or at auto parts stores.
* Safety First: Always prioritize safety. Work in a well-ventilated area and wear appropriate safety glasses.
* Professional Help: If you're uncomfortable performing this task yourself, it's always best to seek professional help from a qualified mechanic. Improperly installing a starter can damage your vehicle's electrical system.
This is a general guide; consult a repair manual for your specific vehicle for accurate instructions and torque specifications. Failing to follow proper procedures could lead to damage or injury.
