All right flat rate mechanic again and
I just wanted to go over a few tips that
will help you replace your o2 sensor.

Because a lot of times over the years
these things, between the heating up and
cooling and the rust a lot of times oxygen sensors
like to get stuck inside the exhaust
manifold or the exhaust itself.

So Probably first off and probably the most
important tip I can give you guys is to
get the exhaust nice and hot before you
attempt to remove this and you wont
necessarily need a torch or
anything like that.

Just run the engine for a while hold the RPMs up to
maybe about 2,000 rpms for five
minutes or so and that will get that
exhaust nice and hot.

That’s going to aid in getting the oxygen sensor
out. Also a lot of
times you’ll be able to break these
loose but they’ll actually start to take
the threads out as you pull it from the
exhaust

The reason why is, the tip inside the exhaust
will get rust build up on it, so as you’re
threading it out the rust will tend to take the
threads of the exhaust out as well.

So what you want to do is just break the o2 sensor
loose and then spray some penetrating
oil down around there and just work it
back a few times.

That’s going save your threads. Also they have some pretty
nice oxygen sensor removal kits out there
that you can find on Amazon or your tool
truck. Whatever you prefer but I actually
picked this one up to Amazon relatively
cheap here https://amzn.to/2IbVcaf it also comes
with a thread chaser.

So if you pull the oxygen sensor out and it does damage the threads
you can run it back down through
before reinstalling it.

You’re always going to want to use some
kind of anti-seize or carbide stuff to.
Most oxygen sensors come with them as well.

Also, I highly suggest you get an OE
replacement or close it. Do not
replace your o2 sensor with a Universal
O2 sensor. Where sometimes they’ll have the wires we you have to wire
in your own pigtail connector.

Those senses are very problematic and a
lot of times will fail just due to poor
connection being for where you spliced
it in. so always go for the OE style
that has a correct connector on it. just
to save yourself a lot of trouble down
the road.

I think that’s about it off
top of my head. but yeah I mean if it doesnt
come out, torches are very handy too.

You would heat up around the o2 sensor
itself and worst-case scenario if that thing
just is not coming out and it
takes all the threads. I have had to
weld a new oxygen sensor bungs onto the
exhaust.

That is worst case scenario.
