Solution

1. Preparation

Gather Tools and Parts: Ensure you have an OBD-II scanner, socket set, wrench set, and a coolant catch pan.
Safety Precautions: Disconnect the battery before performing any repairs. Allow the engine to cool completely.

2. Address Fluid Leaks

Identify Source: If any leaks are found, trace them back to their source (e.g., oil filter, gasket, or hose).
Replace Gaskets or Seals: If the leak is due to a faulty gasket or seal, replace it with the appropriate OEM part.

3. Change Engine Oil

Drain Old Oil: Remove the oil drain plug and allow the old oil to drain completely into a catch pan.
Replace Oil Filter: Remove the old oil filter and install a new one, ensuring it is properly sealed.
Add New Oil: Reinstall the drain plug and fill the engine with the recommended oil type, checking the level on the dipstick.

4. Replace Worn Belts and Hoses

Remove the Belt: Use a wrench to loosen the tensioner and remove the serpentine belt.
Inspect and Replace: Check the belts and hoses for wear, replacing any that are damaged or showing signs of heat degradation.

5. Clean Exhaust Components

Inspect Exhaust: Check the exhaust manifold, catalytic converter, and muffler for signs of fluid accumulation.
Clean: If necessary, clean any areas where oil or coolant may have leaked onto hot surfaces.
