BWD = Borg-Warner, an OEM parts supplier.

Price with online promo code was right.

Fixed idle speed interrmittent low oil pressure warning light flicker.

Has pipe thread sealant applied, no need to add more.

For removal & installation, requires special internally modified 1.062" socket to clear electrical connector.

Before installing sensor, check that Chrysler electrical harness plug fits & the double lock connector works, my second safty lock didn't work, but one lock was good enough, plug is on secure!!!!

Comments about BWD Engine Oil Pressure Switch:

I had an intermittent oil pressure light on my 2005 Dodge Caravan and discovered that it is a frequent problem on that vehicle. I replaced it with the BWD S4178 and the problem immediately continued. I tried a Duralast part and it worked perfectly.

            Comments about BWD Engine Oil Pressure Switch:

            The unit looks different than the OEM unit - my OEM unit was all black, including the the plastic electrical connector and the threaded end. The new one has a white plastic connector and chrome threaded end. No big deal. Fits well, and the electrical connector slides right on. Be sure to put some nylon tape or thread sealer on the threads before installing the new unit. That is the reason I was replacing my - the unit still worker, but it was leaking oil. The new one has metal threads vs. the OEM plastic threads, so I expect it will last longer.

                Resolved problem with erroneous oil indications. Had to purchase a deep socket to replace oil sending unit that cost more that the part but only by 3 dollars. $28 total for part and socket, but that beats $120 at a garage. Two weeks use, seems fine so far.

                  Caused oil pressure light to come on every time the vehicle came to a stop at a light, traffic, or stop sign. Replaced with an OEM Dealer part and problem solved. I would not use an aftermarket part like this again.

                            Same-o-same-o. Tired of the oil light every time you idle but you are quite sure the pressure is good. Replace the sender unit. Also cleared up a small oil drip. Had to research how to unplug to find you slide a locking tab on a 2003 Town & Country.

                                    Hi TY, glad to help you! The engine oil pressure switch is located on the right side rear of the engine block. The switch screws into the engine main oil gallery. To get more specific information on the location of this part I would recommend purchasing a Chilton or Haynes Repair Manual for your vehicle, not only will it show the location and also explain how to install, but you'll find it handy for many more projects on your vehicle. The repair manual part number is 25035.

                                    Hello Scott I will be happy to help you with your question. With removal you do often need a special oil pressure switch socket; most deep well sockets are not deep enough and will damage the connector. Generally for installation you can use an open ended box wrench.

This is roughly 27mm. This switch fits multiple Chrysler, Dodge, Eagle, Jeep, Mitsubishi, Plymouth and Volkswagen from 1996-2010.

The limited lifetime warranty part can be refunded for cash/credit within the 90 days time frame. After that time expires, it can only be exchanged for a new item. So the warranty is valid for the life of the part as long as the customer owns the vehicle.

                                    Hi JReed, glad to help you! The engine oil pressure switch is located on the right side rear of the engine block. The switch screws into the engine main oil gallery. To get more specific information on the location of this part I would recommend purchasing a Chilton or Haynes Repair Manual for your vehicle, not only will it show the location and also explain how to install, but you'll find it handy for many more projects on your vehicle. The repair manual part number is 25040.

                                    Hi Dennis, glad to assist you! The oil pressure switch should be located on the back end of the motor, near the oil filter. For help with your project, I recommend purchasing a Haynes or Chilton repair manual specifically for your vehicle. This should be able to assist you further into detail on how to repair or replace specific parts.
