  • Use the oil filter wrench to remove the old oil filter and allow the oil to drain.
  • Apply a thin layer of new oil to the gasket of the new oil filter.
  • Install the new oil filter by hand until snug, then tighten it 3/4 turn further.
4. Replace Oil Pressure Sending Unit
  • Tools Required: Socket set, wrench.
  • Locate the oil pressure sending unit, usually near the oil filter.
  • Disconnect the electrical connector from the sending unit.
  • Remove the sending unit using a socket or wrench.
