Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Gather tools and materials needed for the repair.

2. Inspect and Replace Power Steering Fluid

Tools Required: Power steering fluid, funnel, clean cloth
Check the power steering fluid level using the dipstick or reservoir markings.
If low, add the manufacturer-recommended power steering fluid until the correct level is reached.
Inspect the fluid color and consistency; if it appears dark or contaminated, replace it:
- Disconnect the power steering return line.
- Allow old fluid to drain into a container.
- Reconnect the return line and fill the system with new fluid.
- Bleed the system as per the manufacturer’s instructions to remove air.

3. Check and Replace Serpentine Belt

Tools Required: Socket set, belt tensioner tool
Inspect the serpentine belt for cracks, fraying, or glazing.
If damaged, remove the belt by releasing tension using a belt tensioner tool.
Install a new serpentine belt, ensuring it follows the correct routing diagram.
Tighten the tensioner and check for proper tension.

4. Transmission Fluid Inspection and Replacement

Tools Required: Transmission fluid, funnel, torque wrench
Check the transmission fluid level using the dipstick; add fluid if necessary.
If the fluid is burnt or dirty, perform a transmission fluid change:
- Remove the transmission pan (ensure to collect the fluid in a container).
- Replace the filter and gasket.
- Reinstall the pan and torque to specifications.
- Fill the transmission with the correct type of fluid using a funnel.
