are the front+ rear o2 sensors the same for install?

I know the o2's are heated becuase thats how i run the power for my wideband!!

when i went to MATIC dealership they neeed my vin they said casue there was 3 differnt types and was almost 140 for one. i said ill pass

but i couldnt get my o2 sen off if my life depended on it. i even hooked up a crestent wrench to it and jacked up the corner of the wrench and still no budge.

is it better to remove them while there cold or hot. i heard both are the best ways. but with my broken arm i think its time to take to midas or something

I'm sure they're rusted in place. You really need an O2 sensor socket or to be able to get a full box end wrench over them to get them loose. You'd want to heat the fitting in the exhaust up to get them out. Heat = expand

thank you, and what and where to get a o2 sens socket? whats different about.

and found out that it was the front pass one, any tips

[GETGONE]

Sensor socket is a deep well socket with the side cut out of it for the wire so you can get a full grip on the nut part of the sensor. If you have enough room the closed end of a box end wrench works well also. Most of the O2's I have done you don't have enough room to swing a box wrench. You should be able to pick up a O2 sensor socket at any parts store.
