Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface, turn off the engine, and allow it to cool.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Oil

Tools Required: Socket set, oil filter wrench, oil catch pan
Sub-steps:
1. Remove the oil drain plug and allow old oil to completely drain into the catch pan.
2. Replace the oil filter using the filter wrench.
3. Reinstall the oil drain plug and tighten to manufacturer specifications (typically 25 ft-lbs).
4. Add new oil of the specified type (5W-20 or as recommended) until the proper level is reached.

3. Inspect and Replace Coolant

Tools Required: Coolant pressure tester, funnel
Sub-steps:
1. Remove the radiator cap and visually check for coolant level.
2. If low, use a coolant pressure tester to check for leaks in the system.
3. Replace any faulty components (like hoses or gaskets).
4. Refill the system with the appropriate coolant mixture.

4. Inspect Exhaust System

Tools Required: Jack and jack stands, flashlight
Sub-steps:
1. Lift the vehicle with jacks to access the exhaust system.
2. Visually inspect the exhaust pipes, catalytic converter, and muffler for damage or blockages.
3. Replace any damaged components using a pipe cutter and exhaust clamps as needed.

5. Perform Compression Test

Tools Required: Compression tester
Sub-steps:
1. Remove the spark plugs to allow access to the cylinders.
2. Insert the compression tester into the spark plug hole.
3. Crank the engine to take readings; repeat for each cylinder.
4. Compare readings to manufacturer specifications (typically around 180 psi for a healthy engine).
5. Address any cylinders with significantly lower readings, indicating possible head gasket failure or piston ring issues.
