Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to ensure safety.

2. Inspect and Replace Serpentine Belt

Tools Required: Socket set, belt tensioner tool, new serpentine belt
Remove the belt tensioner using the belt tensioner tool to relieve tension on the serpentine belt.
Remove the old serpentine belt, inspecting pulleys for wear and damage.
Install the new serpentine belt according to the routing diagram located in the engine bay.
Reapply tension using the belt tensioner and verify proper installation.

3. Check and Replenish Power Steering Fluid

Tools Required: Funnel, power steering fluid
Locate the power steering reservoir and check the fluid level.
If low, clean the reservoir cap, remove it, and add the appropriate type of power steering fluid until the proper level is reached.
Inspect hoses for any leaks or cracks and replace if necessary.

4. Gearbox and Differential Fluid Check

Tools Required: Fluid pump, appropriate gearbox and differential fluid
Remove the fill plug from the gearbox and differential to check fluid levels.
If levels are low, use the fluid pump to add the correct type of fluid until it starts to overflow from the fill hole.
Reinstall the fill plugs securely.
