Ya it'* something stupid like that.

ok... not to steal the thread, but it'* related. My 93 SSEi is only getting 22-24 highway. If I change the O2, would that help the mileage?

If someone chages it, give us a write up! I'd love to do this!

its almost self explainatory. get O2 socket and a wrench. neel on radiator frame support if you are still agile enough. Lean over engine. disconnect the O2 sensor. slide socket over the old one and twist it out. Screw new one in and tighten.

Took me 10 minutes tops including getting a wrench, opening car, poping hood, I removed the engine cover because I wanted to clean it, changing the sensor,and then the reverse process.

All AC Delco O2'* already have the anti seize applied to the threads.

Ok...Here'* your write up. And let me preface by saying "kneeling on the rad support" you're trying to do what? lol

Put a fender cover or towel over the passenger fender. Reach back and follow the O2 wire to the back metal piece it clips to unhook from metal bracket. Unhook connector from engine harness to O2 sensor (same wires as previous step). Using an O2 socket or crow'* foot and long extension loosen O2. Reverse procedure.

A couple of tricks..if it doesn't loosen right up. plug it back in and take the car for a small cruise around the block to heat the exhaust. Now it should jump right out...be careful now it is extremely hot.

it sort of looks like this:



granted I am only 18 so I am still agile enough to do this.

My knee was on the strut mount thinger so no weight on that foot and my other knee was not touching, my weight is actually on my shin. I was doing spark plugs while in that position so the O2 was a little different, but the same basic concept.

Honestly..I'm a typical 5'10" and have no problem leaning over and doing this or sparkplugs from a standing postiion on the side of the car.

Now..if you gotta crawl into a truck to work on it I understand.. I had worked on a 75 in the rain with the hood nearly shut. Tons of room.

Thanks for the pic though...It'* worth a good chucke. I think Steven once sent me pics of a couple of the guys kneeling on their rad supports barefoot...hahaha
