Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a flat, level surface.
Disconnect the negative battery terminal to ensure safety while working.

2. Inspect and Replace Serpentine Belt

Tools Required: Socket set, belt tensioner tool.
Inspect the serpentine belt for cracks, frays, or wear.
If damaged, release tension using the belt tensioner tool.
Remove the old belt and install the new one, ensuring it follows the correct routing.

3. Check and Change Transmission Fluid

Tools Required: Torque wrench, transmission funnel, fluid pump.
Remove the transmission pan or fill plug to check fluid level.
If low or burnt, drain the old fluid and replace it with manufacturer-recommended transmission fluid.
Reinstall the pan or fill plug and torque to specifications.

4. Inspect and Replace Differential Fluid

Tools Required: Socket set, fluid pump.
Remove the differential cover or fill plug to check fluid level.
If low or contaminated, drain old fluid and refill with the correct differential fluid type.
Ensure the cover is securely reattached or fill plug is tightened.

5. Check Power Steering System

Tools Required: Fluid siphon, funnel.
Inspect power steering fluid level and condition.
If low, top off with manufacturer-recommended power steering fluid.
Look for leaks in hoses or the power steering pump; replace any damaged components.
