Disconnect the negative battery terminal to prevent electrical hazards.

2. Inspect and Replace Power Steering Fluid

Tools Required: Fluid pump or syringe, clean container.
Sub-steps:
1. Locate the power steering reservoir and remove the cap.
2. Use the fluid pump to extract old fluid from the reservoir.
3. Inspect the fluid for contamination; if dirty, replace it.
4. Refill the reservoir with manufacturer-recommended power steering fluid.
5. Start the engine and turn the steering wheel side to side to bleed the system of air.

3. Inspect and Replace Serpentine Belt

Tools Required: Socket set, belt tensioner tool.
Sub-steps:
1. Locate the serpentine belt and inspect it for cracks or fraying.
2. Use the belt tensioner tool to relieve tension on the belt.
3. Remove the old belt from the pulleys.
4. Route the new belt according to the belt routing diagram.
5. Reapply tension and ensure proper alignment on all pulleys.

4. Inspect Power Steering Pump

Tools Required: Wrench set, torque wrench.
Sub-steps:
1. Disconnect the power steering lines from the pump.
2. Remove the mounting bolts securing the pump to the engine.
3. Inspect the pump for leaks or damage.
4. Replace with a new power steering pump if necessary, and torque the bolts to manufacturer specifications.
