3. Install a new serpentine belt, ensuring it is properly routed according to the belt diagram.
4. Reattach any removed covers.

3. Check and Replace Worn Hoses

Sub-steps:
1. Inspect hoses for cracks or heat damage, especially near the engine.
2. If damaged, disconnect the old hose clamps using pliers and remove the hose.
3. Install a new hose, ensuring a tight fit with new clamps.

4. Tire Inspection and Adjustment

Sub-steps:
1. Check tire pressure and adjust to manufacturer's specifications.
2. Inspect for any signs of contact with the wheel wells or suspension components.
3. Rotate tires if uneven wear is found or replace them if necessary.
