Solution

1. Preparation

Tools Required: Wrench set, oil filter wrench, oil pressure gauge, OBD-II scanner, clean rags.
Ensure the engine is cool and parked on a level surface. Disconnect the negative battery terminal before starting work.

2. Check and Top Off Engine Oil

Remove the oil filler cap.
Using the dipstick, check the oil level. If low, add the appropriate type of oil as per manufacturer specifications.
Replace the oil filler cap securely.

3. Replace Oil Filter (if necessary)

Place an oil catch pan under the oil filter.
Use the oil filter wrench to remove the old oil filter.
Apply a thin layer of new oil to the rubber gasket of the new oil filter.
Install the new oil filter by hand until snug, then tighten slightly more with the wrench.

4. Change Engine Oil (if necessary)

Drain the old oil by removing the oil drain plug using the wrench.
Allow all oil to drain into the catch pan.
Replace the drain plug and tighten it to the specified torque (typically 20-25 ft-lbs).
Pour in new engine oil through the oil filler cap, using the recommended oil type and quantity.

5. Test Oil Pressure

Connect the external oil pressure gauge to the oil pressure sending unit location.
Start the engine and monitor the oil pressure reading. It should be within the manufacturer’s specified range (usually between 25-65 psi at idle, depending on engine temperature).
If pressure is low, further investigation of the oil pump and internal engine components may be required.

6. Reassemble and Final Checks

Reconnect the negative battery terminal.
Start the engine and let it idle while monitoring for leaks.
Check the oil pressure warning light; it should turn off once oil pressure is normalized.
