Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, flashlight, jack and jack stands.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before inspection.

2. Address Engine Belts

Step 1: Remove the engine cover if applicable.
Step 2: Inspect the serpentine belt for damage. If damaged, proceed to remove it by loosening the tensioner with a socket.
Step 3: Replace the serpentine belt with a new one, ensuring it is properly aligned with all pulleys. Use the manufacturer’s specifications for tension.

3. Brake Inspection and Repair

Step 1: Lift the vehicle using a jack and secure it with jack stands.
Step 2: Remove the wheel to access the brake assembly.
Step 3: Inspect brake pads and rotors for wear. If pads are below the minimum thickness, replace them.
Step 4: Check calipers for proper function. If a caliper is sticking, it may need cleaning or replacement.

4. Tire Inspection

Step 1: Inspect all tires for signs of uneven wear or damage.
Step 2: Rotate or replace tires if irregularities are found to ensure proper grip and reduce friction.
