Here's a general outline of the process. Specifics may vary slightly depending on your exact Cavalier model (2-door, 4-door, engine type, etc.). Always consult a repair manual specific to your vehicle's year, make, and model for precise instructions and torque specifications.
Tools You'll Likely Need:
* Repair manual: Absolutely essential for your specific Cavalier.
* Socket set: Various sizes, including metric.
* Wrench set: Combination and open-end wrenches.
* Line wrench: To avoid damaging the fitting on the power steering pump.
* Drain pan: To catch power steering fluid.
* New power steering low-pressure line: Make sure you get the correct one for your vehicle.
* Power steering fluid: The correct type for your vehicle (check your manual).
* Jack and jack stands: Safety first! Never work under a car supported only by a jack.
* Gloves: To protect your hands from power steering fluid.
* Shop rags or paper towels: For cleanup.
* Torque wrench: For tightening connections to the correct specifications (crucial to avoid leaks).
Steps (General):
1. Safety First: Disconnect the negative battery terminal. This prevents accidental short circuits. Raise the vehicle securely using a jack and jack stands.
2. Locate the Low-Pressure Line: The low-pressure line typically runs from the power steering rack (near the front wheels) to the power steering pump (usually on the engine). Identify the line you need to replace.
3. Drain Power Steering Fluid: Locate the power steering fluid reservoir and carefully drain the fluid into a drain pan.
4. Disconnect the Line: This is where the line wrench becomes important. Carefully loosen and disconnect the fittings at both ends of the low-pressure line. You'll likely need to use a line wrench on the pump fitting to avoid damaging it. Take pictures or make notes as you disconnect things to help with reassembly.
5. Remove the Old Line: Once the fittings are disconnected, carefully remove the old power steering line. It might be clamped or secured in place, so you might need to loosen clamps or other fasteners.
6. Install the New Line: Carefully install the new power steering line, ensuring it's routed correctly and secured properly. Pay attention to the bends and curves of the old line.
7. Connect the Fittings: Carefully connect the fittings at both ends of the new line. Use the line wrench on the pump fitting. Tighten to the proper torque specification (found in your repair manual).
8. Refill the Power Steering Fluid: Carefully refill the power steering fluid reservoir with the correct type of fluid. Check your owner's manual for the correct capacity and type.
9. Bleed the System: Start the engine and turn the steering wheel lock-to-lock several times while keeping an eye on the fluid level. Add more fluid as needed to keep the reservoir full. This helps remove any air bubbles from the system.
10. Check for Leaks: After bleeding the system, carefully inspect all connections for leaks.
11. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
12. Test Drive: Test drive the vehicle and check for any unusual noises or behaviors in the steering.
Important Notes:
* Power steering fluid is messy and can damage paint. Protect your vehicle's paint.
* Power steering fluid is under pressure. Be careful when working with the system.
* Torque specifications are critical. Use a torque wrench to tighten connections to the correct specifications to prevent leaks and damage.
* If you're not comfortable with any of these steps, take your vehicle to a qualified mechanic.
This is a general guide. Always consult a repair manual specific to your vehicle for detailed instructions and safety precautions. Improper repair can lead to serious damage to your vehicle or injury to yourself.
