2. Remove the old serpentine belt from the pulleys.
3. Inspect the new belt for proper size and fit before installation.
4. Install the new serpentine belt according to the routing diagram on the engine.
5. Reapply tension to the tensioner pulley and ensure the belt is secured.

3. Replace Worn Hoses

Sub-steps:
1. Identify any hoses that are cracked, brittle, or leaking.
2. Use a hose clamp tool to remove the damaged hose from its connections.
3. Install the new hose, ensuring it is properly seated at both ends.
4. Tighten the hose clamps securely to prevent leaks.

4. Address Tire Issues

Sub-steps:
1. Inspect tires for uneven wear, bulges, or damage that could cause friction.
2. Replace any tires that show significant wear or damage.
3. Check and adjust tire pressure to manufacturer specifications.

5. Brake System Inspection
