Oil Pressure Switch
Removal and Installation
1. NOTE: The pressure switch-type unit used with the indicator lamp system is not
interchangeable with the variable resistance-type unit called a sender, which is used with the
gauge system. Refer to the Master Parts Catalog for proper parts usage. Installation of the
wrong part will result in an inoperative oil pressure indicating system and a damaged switch
unit or gauge.
Make sure the engine (6007) is turned off.
2. On Aerostar, remove inside engine cover.
3. Disconnect the wire at the switch unit terminal
4. Remove the oil pressure sensor (9278) from its mounting.
5. Apply Pipe Sealant with Teflon® D8AZ-19554-A or equivalent meeting Ford specification WSK-
M2G350-A2 to new switch unit threads.
For installation follow removal procedures in reverse order. Tighten switch to 11-24 Nm (8-18 lb-ft).
