ok I'm waiting on the parts to arrive to my auto zone its the same ones that AB sell so thats good i guess from the looks of it i don't need to get under the car do i?

 

oh you will be getting under the truck

 

To change the O2 sensors? Yeah, you'll need to get underneath for the rear. I have to do my passenger side O2 sensors, but I'm going to try and do the pre-cat one from the top.

Screw the designer who thought it was a good plan to put the connector behind the engine... Just saying.

 

the front ones can be got from the top only, with lots of extensions. and make sure you get/rent an O2 sensor socket- AZ is sure to have one.

 

i have a open end wrench will that not work?

 

I'm only doing the fronts I've been trying for an hour with an open end wrench a 7/8 and a 15/16 neither are able to get a good bite for me to whack it with a hammer and even try to get it off. I've used a lot of wd40 and its just not working. also for when i get to it how do i remove the clip thats covered in oil for the harness i tried to do that a while ago and couldn't get it off.

 

22mm fits too

 

okay ill keep trying its just such an awkward angle on the passenger side and its not wanting to get a grip

 

Squeeze orange or gray clips on plug to release

 

Heat helps
