Park the vehicle on a level surface and ensure the engine is cool.
Disconnect the battery to prevent any electrical issues during repair.

2. Inspect and Replace Drive Belts

Sub-steps:
1. Remove the engine cover (if applicable) to access the belts.
2. Inspect the drive belts for any signs of wear, cracking, or glazing.
3. If damaged, use a socket set to loosen the tensioner and remove the old belt.
4. Replace with a new belt, ensuring correct alignment and tension.
5. Re-check tensioner adjustment and inspect for any misalignment or wear.

3. Inspect Engine Hoses

Sub-steps:
1. Visually inspect all rubber hoses for cracks, soft spots, or leaks.
2. Replace any damaged hoses using pliers to remove clamps and carefully detach them.
3. Install new hoses and secure with clamps, ensuring there are no kinks or tight bends.

4. Check for Fluid Leaks

Sub-steps:
1. Check the engine oil, transmission fluid, and coolant levels.
2. Inspect the undercarriage and engine area for signs of leaking fluids.
3. Clean any spilled fluids with appropriate cleaning agents.
4. Replace any damaged seals or gaskets to prevent future leaks.

5. Reassemble and Final Checks

Sub-steps:
1. Reconnect the battery and ensure all tools are removed from the engine bay.
