Oxygen Sensor Application Guide:

P93H 3.8L GM P/N: 25162693 AC P/N: AFS20 POSN 1
P93H 3.8-1 GM P/N: 25162693 AC P/N: AFS20 POSN 1
Something is wrong with the chart, because in 93, the S/C engine did not use a heated sensor, while the N/A engine did. The part numbers should be different.

Well my GM Parts Book only shows this info for all 92/93's! :? Is it possible you got a 94 style? :?

Is the US Model different from the Cdn Model I wonder then???? :?

Mine is a single wire....unheated. JSeabert's is a heated. He's a 93 NA. Go figure. This is one of the things that caused so much confusion early on. My magic book actually gave me the right number for mine (25162693) but that's the only one listed for 92/93, and Josh's is different. Jr, take a look at the book I sent you and you'll see what I mean. It also shows one part number for 94/95, another for 96/97, and another for 98/99. I don't trust any of this any more......but it's the only apparent bum info in my book.

You guys that didnt buy a o2 socket must be a sight more nimble than I.

I had to go buy a socket but I'm just going to return it when I am done with it.

I just changed mine today with a 8" Adjustable wrench. It was fine and easy to change - I was surprised actually.

The T-stat was more messy but did it. It is running cooler which is nice :)
