Best tool for O2 sensor?

[GNRick]

I have a stock location O2 sensor in factory header. Snap On makes this wrench with an angle to it. However it is over $80. Are there any good alternatives?

I have that wrench and it works the best of any other O2 tools I have.

A 6-point box wrench, a heat wrench, and an 18mm spark plug chaser. Can't go wrong.

Need to really get some heat into the O2 mounting bung, then lean on it with the 6-point box wrench. Once out run a 18 mm spark plug chaser through the bung. Clean out the bung (degrease) and apply fresh anti-seize to sensor (if required, most already have it).

Thanks! I guess I'll have to buy one.:smile:

I use a socket I bought at a local parts store. The socket has a channel cut in the side for the wire to stick out.

I use a regular 7/8'' wrench to remove and install the o2 sensor. It takes about 3 minutes depending on how slow i work.

Problem is, there is no room to install the socket on the O2 sensor and then attach a ratchet to the socket. That "S" hose is too close to the sensor. Unless if you have ATR headers/downpipe and the sensor is in the downpipe.

It's hard to grab the sensor with the wrench, but that is what I used, too. Would just like to purchase a wrench that is made for the job.

Some of the larger auto parts stores have a loaner tool program that requires a deposit for the tool but when you return it you get all of your money back including tax.

I use this program for tools i don't use very often or are too expensive to buy just to have laying around.

BE AWARE!!
Use ONLY sensor safe antiseize...

Stubby 7/8 combination wrench. I have the cutaway socket but prefer the box end of the wrench for ease of working with the wires.

Any chance you could post a pic? Or could you look at the snap on wrench in the link in my original post and describe any difference between yours and the Snap On? Thanks!

Loosen it while hot too... and it won't hurt to hit it with some penetrant if it's been there for awhile.

I moved mine to the downpipe, heated, but easier to change after lead fouling.

O2 socket and a wrench...cant remember the size though.

k.i.s.s. principle rules here. Nothing more than a 7/8" open end wrench.
I can't use a box end because the connector on my heated O2 is too large to fit through the wrench.

7/8 open end...Simple.
