2. Remove any components obstructing access to the leaking area (if necessary).
3. Clean the area thoroughly with a degreaser.
4. Replace the gasket or seal as needed, following the manufacturer’s specifications for torque values.
5. Refill the engine oil to the correct level.

3. Coolant System Check

Sub-steps:
1. Inspect the radiator and hoses for leaks or damage.
2. Replace any damaged hoses or a faulty radiator cap.
3. If the coolant is contaminated or low, flush the cooling system.
4. Refill with the appropriate coolant mixture (consult specifications for type).

4. Brake Inspection

Sub-steps:
1. Inspect brake pads and rotors for excessive wear or damage.
2. Ensure calipers are functioning correctly and are not stuck.
3. Replace any worn brake components as required.
4. Test brake function after reassembly.

5. Replace Worn Belts or Hoses

Sub-steps:
1. Inspect serpentine belts and hoses for cracks or wear.
2. If damaged, remove the old belt or hose using a socket set.
3. Install new belts or hoses, ensuring proper routing and tension.
4. Reconnect any disconnected components and ensure they are secure.
