Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Safety: Disconnect the battery to avoid electrical shock.

2. Inspect and Replace Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; add fluid if low.
If fluid is dirty or contaminated, drain the old fluid and replace it with new manufacturer-recommended power steering fluid.

3. Check and Replace Serpentine Belt

Use a socket set to loosen the tensioner and remove the serpentine belt.
Inspect the belt for any signs of wear or damage.
If necessary, install a new belt by routing it according to the belt diagram under the hood and securing it with the tensioner.

4. Inspect and Replace Power Steering Pump (if necessary)

Remove the power steering pump by disconnecting the inlet and outlet hoses using a wrench.
Unbolt the pump from its mounting bracket.
Install the new pump by reversing the removal steps, ensuring all connections are secure and properly tightened.

5. Reassemble and Refill System

Reconnect the battery and start the engine.
Check for leaks around the power steering pump and hoses.
Turn the steering wheel from lock to lock a few times to bleed air from the system, and check fluid levels again, adding as needed.
