    Default Oil Pressure Sending Unit Location? 5.2L V-8

    I think I need to replace my oil pressure sending unit because the pressure occasionally drops on the gauge, and the engine runs fine.

    Anyone have a part number and location for this sending unit?

    TIA,

    John

    Location is next to the distributor at the rear of the motor behind the air hat,
    sender is at any auto store, around 24skins, for 6 more skins you can get the socket to help mwith the removal.

    Default 1993 – 1995 JGC Oil Pressure Sending Unit (Sensor, Switch)

    1993 – 1995 Jeep Grand Cherokee also fits 1992 - 1996 Cherokee, 1992 - 1995 Wrangler & 1992 Comanche

    On the Jeep Grand Cherokee V8 5.2L, it is located behind the engine, near the firewall next to the distributor on the passenger side and sits vertically, at a right angle to the engine. This is a single wire sensor with a plastic pin to help align it with the unit’s socket. It is very difficult to see, even with a mirror. Follow the wire, which runs behind the distributor, down to the unit which has a snap fit lock on the side nearest the firewall. Use a small screwdriver to open the snap lock. Be sure to keep the oval rubber seal which you will need to put inside the wire socket on the new unit to ensure an oil-proof seal.

    The unit is much easier to replace if you remove the passenger side spark plug and coil wires at the distributor. Make a diagram to ensure proper reinstallation order. The metal fitting at the base of the unit is 1-1/16” in diameter, but is about ¼” deeper than a normal deep socket. Poor design as there is plenty of room for the guts inside the unit and it could easily have been designed for a normal deep socket. Neither Advance Auto nor Auto Zone, etc. had a socket which fit perfectly, not even the Great Neck socket which is labeled for an oil pressure sending unit.

    Snap-On Tools undoubtedly has the correct socket if you want to spend the bucks for use on a sending unit which can last well over 200,000 miles (running low on oil and allowing the engine to overheat will shorten its life). However, the GN socket will engage at least two of the unit’s faces and, with care, the unit can be gentled out and replaced. It does not have to be screwed in all the way, just snug it up. Do not force as it is easy to break the plastic housing. With luck, you’ll never have to do this more than once.

    Socket is available at NAPA (part number 775-9049.) It's a 2-3/4" deep socket.
