dklink2000 Posted October 14, 2005 Share Posted October 14, 2005 I'm a little embarrassed to post this, but I can't seem to figure out how to get the old O2 sensor out so I can change it. The car is a 92 Loyale with a N/A EA82 and three speed auto. The problem is the heat shield for the cat is blocking the base of the sensor. You know, the area with the bolt like pattern. Short of cutting the heat shield off (the mounting bolts have long since rusted into the cover itself) does anyone have any ideas? I would really like to keep the heat shield because the passenger side cv joint is right above it. Quote Link to comment Share on other sites More sharing options...

dklink2000 Posted October 14, 2005 Author Share Posted October 14, 2005 How much did it cost? Maybe I'll stop in there today. Quote Link to comment Share on other sites More sharing options...
PeterD Posted October 14, 2005 Share Posted October 14, 2005 it was too much. something like 15 bucks:-\ Quote Link to comment Share on other sites More sharing options...
idosubaru Posted October 14, 2005 Share Posted October 14, 2005 some penetrating oil (PB blaster or liquid wrench - use nothing else) will help the O2 sensor come out. can you get a good wrench on it? i think i usually do mine in the car with a 22 or 24mm wrench, whatever it is. autozone has tool loaner program - use the tool and bring it back. no cost.

cmiller Posted October 14, 2005 Share Posted October 14, 2005 I need to change out my O2 sensor, its going bad. This is some good info you guys are sharing. Thanks Quote Link to comment Share on other sites More sharing options...
azsubaru Posted October 14, 2005 Share Posted October 14, 2005 I rented an O2 tool set from Autozone to get mine out (91 Loyale). Don't remember the cost, but you get it all back when you return the tool. Drop the exhaust from the engine first (4 bolts), and pull it down so you can get to the sensor. It's very easy to strip the threads so using liquid wrench and jiggling it back forth a lot is a good idea. So is a lot of patience during the removal.

froggymike Posted October 14, 2005 Share Posted October 14, 2005 I just changed mine two days ago. I had the same problem and was in a hurry, so I just broke the old sensor away from the threaded part, then used a 22mm socket to get the threaded part out. To install the new one I used a pair of vice grips to screw it in, being careful that I was actually gripping the nut end of the threads and not the sensor body itself.

dklink2000 Posted October 17, 2005 Author Share Posted October 17, 2005 It wouldn't be such a problem if the hole in the heat shield was a little bigger. Quote Link to comment Share on other sites More sharing options...
