Here's a general outline of the process. Specific steps may vary slightly depending on the exact engine (2.7L V6 or 3.5L V6). Consult a repair manual specific to your vehicle's year and engine for detailed instructions and diagrams. A Haynes or Chilton manual is a good investment.
Tools You'll Likely Need:
* Socket wrench set (metric)
* Ratchet and extensions
* Torque wrench
* Jack and jack stands (crucial for safety!)
* Wheel chocks
* Penetrating oil (like PB Blaster)
* Wire brush
* New starter motor
* Gloves
Steps (General):
1. Safety First: Disconnect the negative (-) battery cable. It's best practice to also disconnect the positive (+) cable, though this is less critical for starter replacement.
2. Access the Starter: The starter is usually located on the driver's side (left) of the engine, near the transmission bell housing. Access will be limited. You may need to:
* Raise the vehicle: Safely jack up the front of the car and secure it on jack stands. Never work under a car supported only by a jack.
* Remove the air intake system: This may involve removing various components like the air filter box, intake tubing, and possibly some heat shields. Take pictures before removing anything to ensure you put it back correctly.
* Remove components obstructing access: This might include the engine's lower splash shield or other parts that block direct access to the starter.
3. Disconnect the Starter:
* Battery cable(s): Locate the large positive (+) and smaller negative (-) cables connected to the starter. Use the correct socket to loosen the nuts, and carefully disconnect the cables. Note the orientation to ensure correct reconnection.
* Starter mounting bolts: The starter is usually held in place by two or three bolts. Use penetrating oil on the bolts if they're difficult to loosen. Remove the bolts and carefully lower the starter.
4. Install the New Starter:
* Clean mounting surfaces: Clean the starter mounting surface on the engine block and the starter itself with a wire brush.
* Install the new starter: Position the new starter in place and carefully align it with the mounting holes.
* Secure with bolts: Tighten the mounting bolts to the manufacturer's specified torque. Check your repair manual for the correct torque specification.
5. Reconnect everything:
* Reconnect the battery cables: Connect the positive (+) and negative (-) cables to the new starter. Ensure they're securely tightened.
* Reinstall all removed components: Carefully reinstall all the parts you removed to access the starter, working in reverse order.
6. Lower the vehicle: Carefully lower the vehicle from the jack stands.
7. Reconnect the battery: Connect the negative (-) battery cable.
8. Test the starter: Try starting the car to confirm the new starter is working correctly.
Important Considerations:
* Repair Manual: A repair manual specific to your 1998 Chrysler Concorde is highly recommended. It will provide detailed diagrams, torque specifications, and other crucial information.
* Torque Specifications: Use a torque wrench to tighten bolts to the proper specifications. Over-tightening can damage components, while under-tightening can lead to failure.
* Difficulty: This is not a simple task. If you are not comfortable working on cars, it's best to take it to a qualified mechanic.
This guide provides a general overview. Always refer to a repair manual for your specific vehicle model and engine before attempting this repair. Improper repair can lead to further damage or injury.
