Here's a general outline. Specific steps and challenges may vary slightly depending on the exact engine (1.6L or 1.8L). Consult a repair manual specific to your 1999 Chevy Prizm 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 (important for proper tightening)
* Pry bar or similar tool
* Jack and jack stands (crucial for safety)
* Wheel chocks
* Wire brush
* Penetrating oil (like PB Blaster)
* New starter motor
* Gloves and safety glasses
General Steps:
1. Safety First: Disconnect the negative (-) battery terminal. This prevents accidental shorts and injury.
2. Access the Starter: The starter is usually located on the engine block, often near the transmission bellhousing. You'll likely need to access it from underneath the car.
* Raise and Secure the Vehicle: Safely jack up the car and secure it on jack stands. Always use wheel chocks on the wheels that remain on the ground.
3. Locate and Disconnect the Starter Wires: There will be at least two large wires connected to the starter: a positive (+) cable and a smaller wire (usually connected to the solenoid). Use a wrench or socket to carefully loosen and remove the nuts securing these cables. Tag or mark them if necessary to ensure proper reconnection. Apply penetrating oil if the bolts are stubborn.
4. Remove the Starter Mounting Bolts: The starter is held in place by usually two or three bolts. These bolts can be difficult to access. You may need to use extensions and a universal joint on your ratchet to reach them. Again, use penetrating oil if necessary.
5. Remove the Starter: Once the bolts are removed, carefully pry the starter away from its mounting position. It might be snug, so use a pry bar carefully to avoid damage.
6. Install the New Starter: Before installing the new starter, clean the mounting surface on the engine block and starter with a wire brush. This ensures a good connection and prevents problems. Carefully align the new starter and install the mounting bolts, tightening them to the manufacturer's specifications (check your repair manual for torque values).
7. Reconnect the Wires: Carefully reconnect the positive (+) and smaller wires to the new starter, ensuring that they are secure.
8. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
9. Reconnect the Battery: Reconnect the negative (-) battery terminal.
10. Test the Starter: Turn the ignition key to start the engine.
Important Considerations:
* Repair Manual: A repair manual specific to your 1999 Chevy Prizm is highly recommended. It will provide detailed diagrams and instructions specific to your vehicle's model.
* Stubborn Bolts: Be prepared for some bolts to be difficult to remove due to rust or corrosion. Penetrating oil and patience are your friends. Don't force anything, as you risk damaging threads or breaking bolts.
* Safety: Always prioritize safety. Use jack stands, wheel chocks, and wear appropriate safety gear.
This is a general guide. Referencing a repair manual specific to your vehicle is crucial for success and safety. If you are not comfortable performing this repair yourself, take your car to a qualified mechanic.
