Use an oil filter wrench to remove the old oil filter.
Prepare the new oil filter by applying a bit of new oil to the rubber gasket.
Install the new oil filter and tighten it according to manufacturer specifications.

4. Replace Oil Pressure Sending Unit (if faulty)

Locate the oil pressure sending unit, usually found near the oil filter or on the engine block.
Disconnect the electrical connector and unscrew the unit using a socket wrench.
Install the new oil pressure sending unit and reconnect the electrical connector.

5. Reconnect Battery and Start Engine

Reconnect the negative battery terminal.
Start the engine and monitor the oil pressure gauge or warning light.

6. Test for Leaks

Inspect around the oil filter and oil pressure sending unit for any leaks.
If no leaks are present, proceed to verify oil pressure.
