Suggestions for oxygen sensor tool

[coppermouse]

Can someone suggest a quality oxygen sensor tool. I don't mind spending a little money, but don't want to spend too much. I know there are a few designs out there. What one works the best

Here is the one I use the most. I have about 10 differant ones but this one is my most used

Does that one fit most domestic vehicles?
I have a 2004 Chevy Silverado.

Thats the one I have. I think the nut on the sensors are all the same size at least all the ones I have done have been. Its a clearance thing, you have to fine one that you can get on your sensor.

I have that same style, works very well. I paid $8 for it at autozone. But yes, most if not all oxy sensors are 7/8"

On really tight sensors, the socket with the slot cut up the side will want to spread. To prevent this, slide a worm type hose clamp down over the socket and tighten it as much as possible and then it will not spread.

I have had to take a chisel in an air hammer or pneumatic rivet gun to catch a corner of a hex and break them loose.

If you just use this for sensors on your own car, (i.e. use it very very rarely), you can rent the O2 sensor tool kit (has three common designs for this tool) from autozone or something like that for free or get that set from harbor freight for like 15 dollars (you can also buy the individual sockets for 5 bucks a piece there). If you do this for a living, then it's a different story...

I have to make a correction. The one posted by MrHoleShot is the style I have. Mine is an ampro from advance. I have used an open end wrench or that style socket on the many 02 sensors I have changed.

If you are replacing it, you can cut the wires or slip the wrench over the connector.

I have the socket from hf and its worked for me my half dozen times but the crowfoot type would also be a good choice for space restrictive applications

I have that too. It's pretty damn stout. I'd like a 1/2"-drive one too though. It's good.

+1. If they're that stubborn i cut the wires off and put a 6-point socket over and use a 24" ratchet/breaker bar.

for stubborn ones i use this. A Lisle 43900. its an attachment for the air hammer.

i mostly use the snapon swr1, but i do have two other snapon's that use a ratchet or breaker bar

This is the same one that I have and it has worked well. I bought another one by accident a few years ago and put it in the classifieds.
02 Sensor

 

[wafrederick]

Snap On also has another version and this one is not cheap,paid $85.00 for from the Snap On dealer down the road in my area.Has a handle just like a 3/8 drive breaker bar with the oxygen sensor wrench attached to it.Sometimes threads get messed up,it is an 18mm x 1.50 thread and you can use a spark plug tap for this.

 

[Tom2]

For real tough ones I just cut off the top of the O2 sensor with a grinder, then use a regular 7/8 socket.

 

[klswvu]

I recommend as many options as possible: o2 socket (w/ wire channel), O2 socket (crows foot), 6 and 12 pt wrench, line wrench. Not only can they be hard to get out, some are in the worst possible locations.

 

[coppermouse]

Yes I agree especially the location. The last one I did that made me want to get the tool is a Hyundai Elantra on the exhaust manifold right where all the rubes join. Almost not clearance between it and the radiator fan. I kind of like the ones with the built in bar dedicated.

 

[coppermouse]

I was going to cut the top off with a sawzaw and use a regular socket, but got it with the visegrips

 

[klswvu]

If I remember correctly, there is an engine option in the 2000 Blazer where one of the downstream O2 sensors requires lowering the sub-frame! It definitely proves they design them for ease of assembly and repair is an afterthought.

agree.......

 

[tonydanzah]

Among the types of oxygen sensors used in vehicles are the single wire oxygen sensor and the heated oxygen sensor. The latter type of sensor features a heating ingredient to help in the warm up which leads to proper operating temperature and to keep up that temperature. For your oxygen sensor to run properly, there are four fundamental conditions that should be considered.

The rest of their posts are on topic, my guess is hit the return key etc and posted accidentally.

This is what I do.

 

[Racr350]

Brake Fluid ftw...nothing "unsiezes" threads like brake fluid. a little brake fluid on there, let it sit for a few minutes then go at it. It will break free. works everytime...

 

[Danglerb]

Stopped at HF while I was out today and picked up the crowsfoot style O2 sensor socket for $3.19 using my 20% off coupon. 3/8 drive, looks pretty strong, but until I take out an O2 sensor with it, hard to tell for sure.

 

[Goinlow]

I have a blue point one that is 6 point on 1 side And 12 point on another. Pretty handy.

I have that one also .. trying to remove a O2 sensor on a Honda Accord and the jaws spread causing the hex on the sensor to become rounded .. .. ended heating the sensor and used a impact socket (after breaking the ceramic portion off) to remove. Something that should have taken 10~15 minutes at the most ended up being 3 hours.
