Yeah, who would have ever thought about that. That's a great website for any general car info by the way.

 

yeah, d2s dont use the wires, its the seam you see on the sensor body itself, i strongly recomend using dielectric grease in the connector, also, the connector is not on the sensor, from that clip you quoted, i really dont think they meant the air runs down the wires to the sensor, but where the wires go into the sensor. dielectric will keep the oil that your engine will leak out of the connectors, i use it every time. also recommend it in crank sensor connectors

 

Well, thankfully, I did in fact use some technician grade dielectric compound that I picked up at Advance. I figured it would help, especially as my driver side pre-sensor seems to be getting a regular oil bath. Oddly though, I'm not leaking significant amounts of oil. Weird. I did not have any problems breaking the old sensors loose or putting in the new sensors. I'm sure the prior issues that I had with my wife's Chrysler were all due to the fact that it's a Chrysler.

 

Whew I am glad that is over......changed both of them. First of all, i would not recommend changing the o2 sensors without having access to an impact gun...here we go.. got the O2 socket at Harbor freight ($4) and a can of PB Blaster (lubercating oil that helps break rusted together nutst & Bolts) at advanced auto...I PB Blasted them twice didnt budge...so I hammered them with a 22mm wrench a few times back and forth...nothing...PB Blasted them again..did this no less than five times.....nothing....breaker bars didnt work......neighbor and I tugged on them twice nothing....kept PB Blasting them...another neighbor comes by...he cant resist a hood that is up..former weekend racer...says boys you ain't gone a get em' that way....get some beer and we will work on this.....sun is quickly going down and I am in a panic..out comes the impact gun (electric) we crank back and forth....nothing...PB Blast them again...the passenger side on comes loose....woohooo...clip is a pain but it goes on after about 20 chances....driver side a whole nother story....we do the same dance back and forth maybe five more times till it comes loose...its gettin dark now so I dont see the wire gets all tangles on a support and pulls out of the connector...now we got to get lights to work....dinner's been ready for an hour now and the old lady is bringing out beers trying to help with the lights but her eyes are telling me im a bozo..anyway pull the o2 sensor try to connect it but it not working....realize they sent me the wrong one....this one fits in...not over.....great...now I have no o2 sensor and the old one is broken...so I take the passenger side one and put it in there for now...till i get my hands on the fellow that sent me the wrong one....ugggghhh! upstream downstream......four hours!!!! I would do it again now that I know what I am doing but man lying under the truck may be 4 inches to work with boohaa!

 

update ....not the wrong one.....apparently there are two o2 sensors in the back also...did not know that....four in total....two front two rear.....ah man! hope the rear one is easier....update to follow!

 

For the rear O2 sensors, let me give you a little tip: remove both O2 sensors first, then take the wires loose from their clips, then unplug the connectors. If you try to do them one at a time, it is very difficult to get your hands on the connectors. If both are out and wires are free, you can pull wires to one side, unplug, and then pull wires to the other side and unplug. It's darn near impossible to unplug the connectors with one hand up where you can't even see them. At least that's what I've found on my D1.
