Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the battery (negative terminal) for safety.

2. Inspect and Refill Power Steering Fluid

Tools Required: Funnel, clean rag
Check the power steering fluid reservoir; if low, refill it with the manufacturer-recommended fluid.
Clean any spills around the reservoir to avoid contamination.

3. Replace Serpentine Belt (if worn)

Tools Required: Socket set, torque wrench, belt tensioner tool
Loosen the tensioner using the belt tensioner tool to relieve tension.
Remove the old belt from the pulleys and inspect the pulleys for damage.
Install the new serpentine belt, following the routing diagram typically found on the engine bay.
Tighten the tensioner back to the specified torque (usually around 15-20 Nm).

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

Tools Required: Socket set, wrench set, fluid catch pan
Remove any components obstructing access to the power steering pump.
Disconnect the power steering lines and allow any fluid to drain into the catch pan.
Unbolt the power steering pump and remove it.
Install the new power steering pump and reconnect the lines (use new seals if required).
Refill the power steering fluid.
