I hate working on this car, it's a 2011 Terrain and Haynes/Chilton's don't have a manual for it yet.

So, anyway I had a code for P422 which is CAT below efficiency, I figure I'd replace the rear O2 on it(it's a 4 banger, only 1 rear sensor).

So I order the GM replacement, and I take the old one out just now and put in the new one. Problem is I can't find any torque specs for this anywhere. What is the general rule here? I did finger tight and probably another half turn, it was getting pretty tight at that point and I didn't want to go any more.

 

Most of the torque specs I found after a quick search were around 30 ft/lb with never seez applied.

Just remember, you might want to remove it one of these days.

 

thanks if I had to guess I'm around that or slightly over.

Not to worried about getting it off one day, it's for the soon to be ex-wife's car.
