If the oil level is low, add the appropriate engine oil (check owner’s manual for specifications).
Recheck the oil level after adding oil.

3. Replace Oil Filter

Use an oil filter wrench to remove the old oil filter.
Apply a small amount of new engine oil to the rubber gasket of the new filter.
Install the new oil filter, tightening it according to the manufacturer's specifications.

4. Inspect and Replace Oil Pump (if necessary)

Drain the engine oil completely and remove the oil pan.
Remove the oil pump by unscrewing the bolts and carefully detaching it from the engine.
Inspect the oil pump for any signs of damage or wear. Replace if necessary.
Install the new oil pump, ensuring proper alignment and torque specifications.

5. Refill Engine Oil

Reattach the oil pan with a new gasket if applicable, and torque it to specifications.
Pour the appropriate type and amount of engine oil into the engine.
Reconnect the negative battery terminal.

6. Start Engine and Check Pressure

Start the engine and let it idle.
Verify that the oil pressure warning light turns off after a few moments.
Monitor for any abnormal noises or leaks.
