    Q:
    How to remove and install the Oil Pressure Switch on Cadillac Fleetwood? Posted by Rande L.
    A:
    For 4.5L and 4.9L to remove and install the oil pressure switch you have to unlock the collar from the switch and then remove the electrical connection and also the oil pressure switch. For installation; line up the fittings to be used on the sensor, coat thread on the sensor with either Teflon tape or thread lock and then fit a new oil pressure switch. Replace the electrical connector and the locking collar, before turning on the unit to check for a leak. In the case of the 4.6L engine, lift the car then unplug the connector from the switch as well as remove the oil pressure switch that is located at the oil filler adapter. To install locate this oil pressure switch at the oil filler adapter and torque to 106 in. lbs. The connector is 2m long, switch or socket is 12Nm, you then connect electrical connector to the switch and lower the vehicle and test for leaks.
