The sensor was very competitively-priced even when compared to online retailers that often charge way less - by the time you factor in shipping, most of their parts are a few bucks more. It's just an oil pressure sender, right? The biggest downside (aside from not being an OEM or OEM supplier) is that most of the "Higher quality" senders have sealant on the threads. I have a huge can of the stuff, so it isn't a big deal, but the casual user or wrencher might not have sealant. You should either use something like Blue Monster sealant on the top threads (not the tip threads), or something like O2 sealant on the threads - NOT teflon tape! And remember not to overtighten the sensor or you'll need to rip apart your entire engine after you crack the housing and oil pours out like crazy. Seems like silly advice, but I've seen pictures of people who did it on the 300M forums, so I know not to do it.

            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 CARQUEST by BWD Oil Pressure Light 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.

                          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.

                          Hi Moe, glad to help you! This part comes with a limited lifetime replacement warranty. 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 Cynthia, 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 25026.
