Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; if low, top it off with the recommended power steering fluid.
If the fluid is dirty or contaminated, drain it and replace it with fresh fluid.

3. Replace Serpentine Belt

Use a socket set to release tension on the serpentine belt tensioner.
Carefully remove the old belt from the pulleys.
Install the new serpentine belt according to the routing diagram typically found on a sticker under the hood.
Ensure proper alignment and tension before releasing the tensioner.

4. Check and Replace Transmission Fluid (if necessary)

Use a wrench to remove the transmission fluid dipstick.
Check the fluid level and condition; if low or dark, replace the fluid.
To replace, drain the old fluid from the transmission pan, replace the filter, and refill with the appropriate transmission fluid.
