Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Check and Top Off Engine Oil

Remove the dipstick and wipe it clean.
Reinsert the dipstick, remove it, and check the oil level.
If low, add the appropriate type of oil (consult owner's manual for specifications) until the correct level is reached.

3. Replace Oil Filter

Using an oil filter wrench, remove the old oil filter.
Apply a small amount of new oil to the rubber gasket of the new filter.
Install the new oil filter, tightening it securely by hand.

4. Test Oil Pressure

Locate the oil pressure sending unit and disconnect the electrical connector.
Remove the sending unit using a socket wrench.
Install an external oil pressure gauge in place of the sending unit.
Start the engine and monitor the oil pressure reading; it should be within the manufacturer's specifications.

5. Inspect and Replace Oil Pump (if necessary)

If oil pressure is low, remove the oil pan to access the oil pump.
Disconnect any hoses and electrical connections.
Remove the oil pump from its mounting position.
Install the new oil pump, ensuring proper alignment and torque specifications are met.

6. Reassemble and Fill Oil

Reinstall the oil pan with a new gasket, tightening bolts to the specified torque.
Reconnect any hoses and electrical connectors.
Fill the engine with the appropriate type and amount of oil.
