Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts while working.

2. Inspect and Replace Worn Belts

Tools Required: Socket set, torque wrench, belt tension gauge.
Check the serpentine belt for cracks, fraying, or signs of wear.
If damaged, remove the belt using the socket set to loosen the tensioner.
Replace with a new belt, ensuring correct routing and appropriate tension.
Torque the tensioner bolt to manufacturer specifications (typically 15-20 ft-lbs).

3. Inspect and Replace Worn Hoses

Check all rubber hoses in the engine bay for any signs of cracking or deterioration.
If found, remove the affected hose using the appropriate clamps and replace with a new one.
Ensure all connections are tight and secure to prevent leaks.

4. Examine and Service the Brakes

Tools Required: Jack, jack stands, lug wrench, brake cleaner.
Raise the vehicle and remove the wheel to access the brake components.
Inspect brake pads and rotors for excessive wear or damage.
If pads are worn, replace them and ensure the calipers are functioning correctly.
Clean the brake components with brake cleaner and reassemble.

5. Tire Inspection and Maintenance

Inspect tires for uneven wear, bulges, or damage.
Rotate or replace tires as necessary to ensure even wear.
Check tire pressure and inflate to the recommended levels.
