Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool down completely before starting work.

2. Inspect and Clean Engine Components

Tools Required: Socket set, rags, engine degreaser
Check for oil or coolant leaks:
- Inspect valve cover gaskets, oil pan, and hoses for any leaks.
- Clean any residue with engine degreaser and rags.
- Replace any damaged gaskets or hoses.

3. Check and Replace Transmission Fluid

Tools Required: Torque wrench, funnel
Inspect the transmission fluid:
- Remove the transmission dipstick (if applicable) and check fluid level.
- If the fluid is low or burnt, drain and replace it with the manufacturer-recommended fluid.
- Torque the transmission pan bolts to the specified value (refer to the service manual).

4. Inspect Brake System

Tools Required: Jack, jack stands, lug wrench, brake cleaner
Remove the wheels to access the brake components:
- Inspect brake pads for wear; replace if they are below manufacturer specifications.
- Check brake rotors for signs of overheating; machine or replace if necessary.
- Clean calipers and rotors with brake cleaner.

5. Examine Exhaust System

Tools Required: Wrench set, exhaust clamps (if needed)
Inspect for leaks:
- Check exhaust manifold, pipes, and muffler for any cracks or holes.
- Repair or replace any damaged components, ensuring all clamps are secure.
