Solution

1. Preparation

Gather tools and materials for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical issues during servicing.

2. Inspect and Top Off Power Steering Fluid

Tools Required: Rags, funnel.
Open the power steering reservoir cap and check fluid level.
If low, add the recommended power steering fluid type as per the owner's manual.
Inspect the fluid for contaminants or a burnt smell, which may indicate pump failure.

3. Inspect Power Steering Hoses and Pump

Tools Required: Wrench set, flashlight.
Visually inspect hoses for cracks, frays, or leaks.
Check the power steering pump for signs of leaking fluid around the seals.
If leaks are found, replace damaged hoses or the pump as necessary.

4. Check and Replace the Serpentine Belt

Tools Required: Socket set, torque wrench.
Inspect the serpentine belt for fraying, cracking, or wear.
If damaged, remove the old belt by loosening the tensioner and slipping it off the pulleys.
Install a new belt, ensuring it is routed correctly around all pulleys. Torque the tensioner to manufacturer specifications.

5. Test Power Steering Pump Operation

Tools Required: Pressure gauge (if applicable).
Reconnect the battery and start the engine.
Turn the steering wheel from lock to lock while listening for noise.
If noise persists, use a pressure gauge to test pump output; replace the pump if it fails to deliver adequate pressure.
