Solution

1. Preparation

Tools Required: Socket set, wrench set, oil catch pan, OBD-II scanner, shop towels.
Ensure the vehicle is parked on a level surface and the engine is cool. Disconnect the negative battery terminal to prevent electrical issues.

2. Identify and Repair Leaks

Sub-steps:
1. Clean the engine bay with a degreaser to remove old oil residue.
2. Run the engine and look for fresh oil leaks while inspecting the oil filter and oil pan.
3. If a leak is found, replace the damaged oil filter or seal as necessary.
4. Use a torque wrench to ensure the oil filter is tightened to the manufacturer's specifications.

3. Replace Oil and Filter

Sub-steps:
1. Remove the oil drain plug using a socket wrench and allow the old oil to drain into an oil catch pan.
2. Replace the oil drain plug and tighten it to the specified torque (usually around 20-25 ft-lbs).
3. Replace the oil filter with a new one, ensuring the rubber O-ring is lubricated and the filter is tightened to specifications.
4. Refill the engine with the appropriate oil type and quantity as specified in the owner’s manual.

4. Check for Overheating

Sub-steps:
1. Inspect the coolant level and top it off if necessary.
2. Check the radiator and hoses for leaks or damage.
3. Ensure the thermostat and cooling fans are functioning correctly.

5. Final Inspection

Start the engine and let it run for a few minutes while monitoring for leaks and smells.
Check that the engine warning light is off; if not, re-scan for error codes.
