Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Allow the engine to cool before starting work.
Tools Required: Wrench set, oil filter wrench, mechanical oil pressure gauge, OBD-II scanner.

2. Check and Add Engine Oil

Sub-steps:
1. Open the hood and locate the oil dipstick.
2. Remove the dipstick, wipe it clean, and reinsert it.
3. Pull it out again to check the oil level.
4. If oil level is low, add the manufacturer-recommended oil until it reaches the correct level.
Safety Warning: Ensure the engine is cool to avoid burns from hot oil.

3. Inspect Oil Filter

Sub-steps:
1. Locate the oil filter and inspect it for leaks or damage.
2. If necessary, remove the oil filter using an oil filter wrench.
3. Install a new oil filter, ensuring it is tightened according to the manufacturer’s specifications (typically hand-tight plus a quarter turn).
Parts Required: New oil filter.

4. Replace Engine Oil

Sub-steps:
1. Drain the old engine oil by removing the oil drain plug (use a wrench).
2. Allow the old oil to fully drain into a suitable container.
3. Replace the drain plug and tighten it securely to the manufacturer's torque specifications.
4. Refill the engine with new oil as specified in the owner's manual (typically 5W-30 or 5W-40).
Parts Required: New engine oil.
Safety Warning: Ensure the engine is cool before draining oil.

5. Test Oil Pressure

Sub-steps:
1. Disconnect the oil pressure sending unit connector.
2. Install the mechanical oil pressure gauge in place of the sending unit.
3. Start the engine and observe the oil pressure readings; compare with the manufacturer’s specifications.
4. If pressure is low, further investigation of the oil pump and engine internals may be necessary.
Tools Required: Mechanical oil pressure gauge.
