Solution

1. Preparation

Tools Required: Socket set, screwdrivers, OBD-II scanner
Gather necessary replacement parts based on findings from diagnostic steps.

2. Inspect and Replace Belts

Open the hood and visually inspect all serpentine belts for wear, cracks, or fraying.
If a belt is worn or damaged, loosen the tensioner using a socket wrench.
Remove the old belt and replace it with a new one, ensuring proper routing according to the belt diagram.
Tighten the tensioner to the specified torque (consult vehicle service manual for specifications).

3. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir and check the fluid level; if low, top off with the manufacturer's recommended fluid.
If the fluid is dirty or has debris, drain and replace the fluid.
Inspect the power steering pump for leaks and ensure all connections are secure.

4. Inspect Transmission Fluid

With the engine running, check the transmission fluid level using the dipstick.
If low, add the appropriate type of transmission fluid as specified in the owner's manual.
If the fluid is dark or has a burnt smell, consider performing a transmission fluid change.
