Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent any electrical issues while working.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir under the hood.
Remove the cap and check the fluid level; add the manufacturer-recommended fluid if low.
Inspect the fluid for contamination (should be clear, not dark or gritty).

3. Inspect for Leaks

Visually inspect all power steering hoses and connections for signs of leaks.
Use a clean rag to wipe any fluid residue, then monitor for new fluid formation.

4. Replace Power Steering Pump (if necessary)

Disconnect the negative battery terminal.
Remove any components obstructing access to the power steering pump.
Unscrew the power steering pump from its mounting bracket and disconnect the fluid lines (be prepared for fluid spillage).
Install the new power steering pump, ensuring all connections are tight.
Refill the power steering fluid and bleed the system by turning the steering wheel from lock to lock with the engine running.

5. Inspect and Replace Serpentine Belt (if necessary)

Visually inspect the serpentine belt for cracks or fraying.
If damaged, use a belt removal tool to release tension and remove the old belt.
Install the new serpentine belt according to the routing diagram found near the engine.
Reconnect the negative battery terminal.
