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 filter.
Install the new oil filter according to manufacturer specifications.

4. Replace Engine Oil (if dirty or degraded)

Tools Required: Socket set, oil catch pan, funnel.
Remove the drain plug using a socket set and let the old oil drain into the catch pan.
Replace the drain plug and torque it to the manufacturer's specifications.
Fill the engine with new oil through the oil fill cap using a funnel.

5. Check Oil Pressure Sending Unit

Tools Required: Multimeter or oil pressure gauge.
Locate the oil pressure sending unit and disconnect the electrical connector.
Test the unit with a multimeter to ensure it is functioning correctly.
If faulty, replace the oil pressure sending unit.
