Okay, I ask this for three reasons:

1. My car is in the shop so I cannot tell where the O2 sensor is.
2. Haynes manual has dick for info, alas not even a mention of the O2 sensor.
3. I tried searching the Forums (1st Gen only) but pulled up no results about it.


Anyways, '85 GSL-SE 13B, how hard is it to R&R the O2 sensor? I purchased a crow foot O2 socket instead of the normal O2 sensor socket because I figured it would be in a tight fit. I also have a breaker bar to slip over the rachet for extra leverage; I know how much of a pain replacing a rusted/stuck one is.

Any help/suggestions would be greatly appreciated.

 

for the 13b, im not to sure...but as far as i know ...the 12A's do not have one...they may not have used thouse in the 13b's untill 86.......

 

There is a bung for an o2 on the racing beat header on my SE.

So I imagine that's about where it's located on a stock manifold.

 

There are non on the 12a ... the O2 sensor is used for FI cars mostly, you can get one done aftermartket for tuning.

 

dj55b, are you replying to zduford? Because I know I stated what my vehicle was/has.

 

it's sitting right on top of the exhaust manifold, super easy to get to.

 

Easy to get to, but a pain in the *** to get leverage on. I would suggest putting the car on jack stands and working from down below. If you look over the passenger front wheel you can see the O2 sensor on the manifold, just underneath the fire wall. Also be sure to lubricate the snot out of it.

Good luck

 

I don't mean to hijack your thread, but how about installing one on a 12a RB header? It has a collector right before the cat (gutted). any idea where to install the bung? and how deep the sensor should go?
