Here's a general overview. Specific steps and tools may vary slightly depending on the exact model and year of your Neon. Always consult a repair manual specific to your vehicle for detailed instructions and torque specifications. A Haynes or Chilton manual is a good investment.
Tools You'll Likely Need:
* Jack and jack stands: Essential for safely working underneath the car.
* Wheel chocks: To secure the car.
* Socket wrench set: Various sizes, including metric.
* Ratchet: For the socket wrench.
* Wrench: Possibly for holding the tensioner pulley bolt.
* Pliers or locking pliers: May be needed to compress the tensioner.
* New tensioner pulley: Get the correct replacement part for your Neon.
* Shop rags or paper towels: To clean up fluids.
* Safety glasses: Always protect your eyes.
* Gloves: To protect your hands.
* Possibly a serpentine belt tool: This makes it much easier to deal with the tensioner.
General Steps (Consult your repair manual for precise details):
1. Safety First: Disconnect the negative battery terminal. This prevents electrical shorts. Raise the car securely using the jack and jack stands, and engage the wheel chocks.
2. Access the Tensioner: Locate the serpentine belt tensioner pulley. It's usually on the bottom/side of the engine near the serpentine belt. You'll likely need to remove some components to get good access; this is where your repair manual will be crucial.
3. Remove the Serpentine Belt: This is usually the hardest part. You'll need to loosen the tensioner pulley (using the appropriate tool or method; sometimes a special tool is needed, sometimes a wrench and leverage). Once tension is released, the belt should be easily removed.
4. Remove the Old Tensioner Pulley: Depending on your Neon's configuration, this might involve removing bolts and/or a bracket. Again, your repair manual will be vital here.
5. Install the New Tensioner Pulley: Install the new pulley, following the reverse order of removal. Make sure everything is correctly aligned and tightened to the manufacturer's specifications (found in your repair manual).
6. Reinstall the Serpentine Belt: Carefully route the serpentine belt around all the pulleys according to the routing diagram (usually on the underside of the hood or in your repair manual). Ensure proper tension on the belt.
7. Lower the Car: Carefully lower the car from the jack stands.
8. Reconnect the Battery: Reconnect the negative battery terminal.
9. Check for Leaks and Proper Function: Inspect for any fluid leaks. Start the engine and check for any unusual noises from the belt or tensioner. Ensure the belt is properly tensioned and running smoothly.
Important Considerations:
* Tensioner Tool: A serpentine belt tensioner tool specifically designed for your Neon's engine will significantly simplify the process of removing and installing the belt.
* Torque Specifications: Always use the correct torque specifications for all bolts. Over-tightening can damage components; under-tightening can cause looseness and failure.
* Repair Manual: A repair manual is absolutely crucial for this job. It will provide detailed step-by-step instructions, diagrams, and torque specifications specific to your car's make, model, and year.
If you lack experience with automotive repairs, it's strongly advised to seek professional help from a qualified mechanic. Improper repair could lead to significant engine damage.
