Solution

1. Preparation

Tools Required: Socket set, torque wrench, mechanic's stethoscope, fluid catch pan
Ensure the vehicle is on a flat surface and the engine is off before beginning work.

2. Inspect Power Steering System

Locate the power steering reservoir.
Check the fluid level; if low, top it up with the recommended power steering fluid.
Inspect the reservoir for cracks or leaks.
If necessary, replace the power steering fluid and bleed the system to remove air.

3. Check Serpentine Belt

Visually inspect the serpentine belt for signs of wear, fraying, or glazing.
If damaged, loosen the tensioner using a ratchet and remove the old belt.
Install a new serpentine belt following the routing diagram on the engine bay.
Tighten the tensioner to the specified torque (usually around 15-25 Nm, but check manufacturer specs).

4. Inspect and Replace Alternator (if necessary)

Disconnect the negative battery terminal to avoid electrical shock.
Remove the serpentine belt from the alternator.
Unplug the electrical connector from the alternator.
Remove the mounting bolts securing the alternator and take it out.
Install the new alternator, ensuring it is properly aligned and secured with bolts.
Reconnect the electrical connector and the serpentine belt.
