Solution

1. Preparation

Tools Required: Socket set, screwdrivers, flashlight
Gather necessary parts based on findings from diagnostics.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace the Serpentine Belt (if damaged)

Sub-steps:
- Locate the serpentine belt and check its condition.
- If frayed or damaged, remove the tensioner bolt using a socket wrench.
- Slide the belt off the pulleys and replace it with a new belt.
- Reinstall the tensioner and ensure the belt is seated correctly on all pulleys.

3. Check and Replace Worn Brake Components (if applicable)

Sub-steps:
- Remove the wheel and inspect brake pads and rotors for excessive wear.
- If the pads are worn down or the rotors are damaged, replace them using a socket set.
- Reassemble the wheel after replacing the brake components.

4. Address Overheating Issues (if detected)
