procedure to replace O2 sensor?

[bgambino]

I would like to replace the O2 sensor in my 91 loyale 4wd non turbo wagon

Whats the procedure to get it out without ripping the threads up?

should I buy the special socket or will a box wrench work well enough?

should I put anti seize on the new one?

thanks

the last one I did I used a crescent wrench and elbow grease.I did use antiseize though.

22mm wrench or special socket; whatever you want. I prefer the socket since I can use my 18" breaker bar to make short work of the deal.

 

Drop the Y pipe from the heads so you have plenty of room to swing tools. It's fairly straightforward. Remove, unplug, screw in new one, plug it in, fire it up!
