How to Properly Maintain the Oil Pressure Switch and What Steps Are Involved for a Lincoln Navigator?

Service of the oil pressure switch begins with supporting and raising the vehicle. You should disconnect the electrical connector from the oil pressure switch before removing the switch. Replace the switch only after cleaning its threads and applying Pipe Sealant with Teflon® D8AZ-19554-A or an equivalent product which matches Ford specifications WSK-M2G350-A2 and ESR-M18P7-A. A proper installation will involve performing the removal steps in reverse order.
