Pro Tip: If you are taking out the o2 sensor because it is a bad sensor, you can cut the wire in order to get the box end on there, without altering the wrench.
usually they are not bad just need to be cleaned.
There are no such thing as bad sensors. It is either faulty or operational. There are BAD children but not sensors
Or you can bend the cable like a u and pull it through the wrench 6 sided without doing damage
If you change enough of them as professionals do then you just get a good made socket that doesn't spread. Yes you'll save time but when you get paid by your efficiency then you don't have time to mess around wondering what to do next.
When you get old you can sell that tool for about 1/2-3/4 of what you paid for it unless you bought it used as well then you've made your money off of it and selling it even at half isn't that big a loss @ retirement time.
No brainer!!!!
I thought you are gonna remove the o2 sensor with just a hose clamp. It got me so interested.
Nice custom exhaust work sweet welds bra! That socket ain't gonna spread, and if it did the small ass clamp wont do anything. 25+ years as a tech! a 7/8 box end fits over most connectors FYI..
I thought the same thing! That's why I had to watch this video!
Lol me too. All that for nothing
Same here. That's why I gave it a "thumbs down" for inaccuracy / click baiting.
I don’t know why, but this is one of my favorite videos on UA-cam
Love it. Common freaking sense. I’ve been using penetrant, heat, two worthless O2 adapters, a hammer, a sledge hammer and a tug-boat … I will try this out. Thanks!
where'd ya get the tug boat ?🙃
Hahaha! I'm a mechanic . I love the way you were talking about engineers. The stuff we go through is ridiculous. Good video! cracked me up . 👍
Every time you have to work on a car, you ask yourself where would be the worst place to put a component in the car? Then you look and that's where the part is 😄, never fails.
@@everydayirace in audi they are the best of the best
A pipe wrench has always worked for me . Might leave a couple grooves on it but unless you run over somebody no-one ever sees it .
LOL
🤦♂️😂🤣
I'd like to see you use a pipe wrench on one that's between the engine and firewall , the ones where you can barely get a wrench on 😊
That works! I pretty much rounded mine off with wrenches. A guy at NAPA suggested I try a pipe wrench. I put my jack bar on the end of it for leverage and twisted it right out.

Great tip. One other thing is you can grind or trim the outside part of the locking tab to allow it to go through the box end wrench. The amount needed to be removed won't compromise the integrity of the ability to stay locked. Another is to use a pair of Vise Grip around the socket to keep it from spreading. To prevent damaging the socket from the Vise Grip teeth, wrap the socket with a thin piece of metal first then clamp down on the socket. Last option is to draw a diagram of the location of each wire in the plug and remove each wire with a wire connector removal tool. What's funny is in the past few day's I've seen advertisements of a complete set of these tools that are different sizes and shapes. Working as a motorcycle, PWC, ATV, UTV technician and a machinist, I've had to make tools for various applications to get the job done. I'm retired from working on them and and now behind the counter and the thing I miss most is working at the motorcycle shop that was also a machine shop performing different types of fabrications.
Running your engine for 3-5 minutes to get the exhaust warm also does wonders for making it easier to break loose a sensor. That, with some pb blaster.
Beat me to it!!!
Pipe wrench works every time
This works for me. Run engine for 1-2 minutes to warm up the exhaust system some. Take some 'Freeze it ' spray and spray the sensor ONLY to cool it down. This will shrink it slightly and it will come right out with no issues!
Thanks for the tip im trying to change one on my truck
Now THIS is a good tip.. thanks
that's the way of installing shrink fit bearings heat one and cool the other on dry ice
Did it work?
My o2 sensors are stuck. I will try today if this works
Always try to tighten everything before you loosen them
Along with lots of penetrating oil. Let it soak overnight if possible. Tighten, loosen, tighten, loosen, tighten, loosen...
This is a great idea. I always drive the vehicle for a while and let the exhaust heat up good and then use the O2 adapters to break ‘‘em free. This has always worked well for me as the O2 sensor usually breaks free easily with the exhaust hot and expanded a little. I will remember your vid if my adapter ever slips
Drove for 20 minutes to heat up the pipes and it broke loose with little effort . Heat works wonders .
Great tip! I was taking out an O2 sensor and it was starting to round off. Followed your tip and came out smooth as butter. Thanks!
Glad to hear it worked for you.
Yup. Any split in a socket (or gap in open ended wrench) will spread if under enough pressure. The hose clamp should keep it from opening. A small "C-clamp" might work, if there's enough space under the vehicle, or if it's tight and secure enough before trying to force things. Great tutorial, great video. Thank you.
Great tip! This saved my bacon tonight. After I finally decided to cut the wires on the old sensor I still couldn't get my 7/8 inch box wrench in the correct position (due to limited space) and the wrench alone did not provide enough leverage. I did not have a cheater bar (pipe) wide enough to slip over the open end of the wrench to apply leverage. I did have on 'loan' to me the same OEM Oxygen Sensor Socket Set from Autozone but discovered 3/8th inch drive crowfoot socket was actually cracked (no doubt it had been used by many people previously) and was spreading open and rounding over the edges of the sensor. Ugh! The band clamp trick bound the socket tightly together and using an appropriate sized (width and length) cheater bar I did have for my socket wrench it gave me the leverage to pop that sensor loose. That was a pleasing sound to hear. Yay!!! This worked when none of the other tools would. Thanks again for the fabulous tip.
Great to hear it helped you out 👍
I had a vehicle service garage for over forty years,and on the vehicle it's usually too tight a space for a breaker bar to fit ,so if the sensor is being replaced anyhow we'd cut the top off with the small air cutter and then oxy/acc cherry red hot and remove with a socket.The biggest problem was not about removing them but being careful not to leave any metal behind in the threads on the exhaust pipe.
Pretty sure there is an 18mm tap to clean up the threads.
@@jsteganius6969 right you are.
Heating up the surrounding area will almost always ruin the threads if you turn while red hot. A better way is to heat until red, then immediately douse with water. I've done it many times and it helps break it loose without affecting threads. The biggest thing is the initial breaking loose after being rusted in, after that it can usually be unscrewed by hand
I use vise grips to prevent that spreading. They also add pre-tension to the actual tool
Is he keeping the wire
A properly designed flare wrench would work. Most flare wrenches are cut down so that they can be used in tight spaces like an open end or box wrench. Needing that amount of clearance isn't an issue with most oxygen sensors.
This is a great idea. I've had a few of these that were ridiculously tight with no work space. I'm sure I will try this someday.
I appreciate your dialectical analysis of the capitalist system. Solidarity, comrade. Let us seize the means and make the world better, one O2 sensor at a time.
If sensor is defective, cut the wire. You can use a 6 point 22mm wrench after.
I think this guys on to the right track here
He already mentioned that option in the video
@@Charlie_Crown he mentioned a 12 point box end, not 6 point….
@@jdwithheld8915 he mentioned the 'cut the wire' option, use of whatever you want to after that is implied 👍
I agree...6 point not 12 point is essential
Just changed out an O2 sensor and was glad I watched your video in advance. 20+ year old O2 sensor on a Taurus 3.0 OHV. It was the sensor on the back manifold before the cat. Using the split socket with some extensions was the only way to go. Hoping for the best, but also planning for the worst, I put a hose clamp on the socket right from the start. At one point I had a 30" pipe extension on the breaker bar handle and I know it would have popped the socket without the hose clamp. At that point I considered heating with a torch, but getting it in back there looked too dicey. I started the engine, had already been warmed up a few minutes, and let it idle for about 5 more minutes. Left the split socket on the O2 sensor since it had gotten hot and didn't want to fool with loosening the hot hose clamp at that point. This may have helped things, the hot socket really heating up that sensor with the engine running. When the senor snapped loose, and you know the sound, I was sure I had stripped the threads because it came out so easily. To my delight the threads were intact. Check engine light is off now. Thanks again.
This worked! Thank you Sir! So I sprayed PB Blaster let it sit for about 20 min. Attached the socket with the hose clamp, got my breaker bar with a piece of pipe end and there it went! Felt like I hit a small lottery😆
I've always heated the base that the sensor screws into with no problem. learned years ago though to use MAP gas instead of propane as it burns much hotter.
You can get MAPP gas? Where?
Mapp gas no longer exists.. The newer map pro is no better than propane... 100° difference
Yes. Propane actually has water 💦 in it LOL. Who would believe that? But it is true. That is why it is cooler. And is not as good when you use silver solder or brazing
Everyone says propane isn’t as hot as map that you can’t get… at what temperature does metal stop getting hot at? I mean I’m pretty sure with a continuous source of flame it’s going to continue getting hotter… may take a minute longer… but it’s still gonna get hot… my son always says it’ll come out once it’s liquid!
I'm in Ontario and "CAN" purchase MAPP fuel everywhere. It burns at 3,730° Fahrenheit. (used to buy propylene fuel/was discontinued. Approx.100° less). PROPANE burns at 3,560° Fahrenheit. Not much of a difference. Alot of times you need to keep heating repeatedly and spraying also. The more heat the better it works. Soon as you see it break it's hold, you can turn it back and forth repeatedly (1/10th) of a thread and this will help break up all the crap on the threads. The key is having patience and using alot of heat, & nut buster, then using the technique of breaking the rust on the thread's. It's a crappy job when there welding in practically, sometimes may take 20 mins before you can break the hold. You need to be careful you don't wreck the thread's.
I just did all four o2's on my F150. It was a pain in the ass, that's for sure, but once you get the pipe/ surrounding area HOT 🔥 enough, they come right out. Mine were original, 16 years they were practically welded into the pipe. 🇨🇦
Awesome. Another option: you can actually pop the individual wires out of the connector without damaging it - can use a pin or a tiny screwdriver, they make little tools that 'weatherpack' connectors that work great. That way you can save the sensor, save the connector, and get the box-end of the wrench over. Also, I think buying a high end oxygen sensor socket might be money well spent - the cheapy amazon ones are soft metal and spread as you say. Either way, hose clamp trick is sweet - definitely using that next time I get a stuck sensor!!
Thank you so much Man! Clever idea save me for the rest of time, your awesome 😊
Learn something new even with 20 yrs of experience....Great job sir...
It's best to heat up the exhaust pipe fitting before attempting to loosen the sensor.
Why doesn't this have a Million hits? This is freakin genius.
Thanks.
Genius! You got me out of of a deep, dark hole and I thank you sir!
You're welcome 👍
Great tip / trick! Thanks for sharing! Will try it out next time I do a o2 sensor.
7/8” line wrench works great! 👍
There are two more options that work really well also. You could always get a pick set or a small screwdriver and dislodge the terminals out of the plastic connector. The second option is you can buy a 7/8 socket for about five bucks from The Parts House die grinder and cut you a slot in the side and then you have your very own oxygen sensor socket for cheap.
How about cutting the tab off?
@@1thinkhealthy that's what I thought too
HB sells the slotted ones for 5 bucks as well I believe. Got another from them just in case but I already have a master set for all type of o2 sensors for all angle types.
Or just cut the wires and reconnect them afterwards
@@Adamsautoamerica that's what I thought too but it messes with the ohms resistance and knackers it
Wow super simple and very effective! Crazy how we overlook the simplest solutions now days. Good job :)
The voice of truth & reason, very accurate description of auto designers👍👍👍
I altered a 12 point spanner to do the same thing as that kit, i just used an angle grinder to put a slot in the end of the spanner big enough to slide the wire through and cut the open end off and welded and flattened the end of a hollow heavy duty tube to the cut off end. Made a stubby one too just incase the sensor is in a tight spot. Like the hose clap idea, good thinkin sir !
Nice trick but I would've just cut the wires I'm not gonna reuse the O2 sensor if it's bad... I'll definitely have to remember this when someone I know is doing theirs
This totally worked for me thanks. It was a frozen sensor in a difficult spot!
Love it. Simple solution that works!
Have been using a 7/8" "line wrench" for years without issue. I bought it for doing front end alignments years ago and it will take a hammer without opening up. BTW, for those who say to cut the plug off, you can usually reuse the sensor if you are changing the cat because that is weak. I have found weak cats on many vehicles that have multiple cats and high miles. (over 200k)
You can reconnect the wires and reuse the sensor
Maybe a flare nut wrench would work too, or try vise grips....
Thats probably my problem but i hope not...sigh
The oxygen sensor split hex socket I bought was really loose so I used my hydraulic press to squeeze the opening smaller for a tight fit and it worked just like that. Did not have to use a hose clamp. Worked for me fella.
Simple idea. But it works great. Thanks man.
Great tip my man. Going to try this next time i have to remove those pesky O2 sensors
Gonna try this! Thanks!!
Dude, works like a charm. I had 2 sensors that started rounding off because sockets kept spreading. Tried hose clamp. Boom, both came out. 🤘🏻🇺🇸
Glad to hear.
Was just having this happen causing misfires and bad mpg I seem too have misplaced my open socket :/
Smart move will try it myself! Thanks for your video!!
Watching this was funny. It was EXACTLY what happen to me...well done
Good video..... never thought to do as you did with the hose clamp...
I have multiples of every size and I never get rid of my old wrenches cuz I cut notches in the boxed end just for these kind of situations
Great idea.
Genius idea! Thanks for sharing! 🙌🏼 God bless!
Thank you very much, especially for older cars with lots of corrosion :)
not all O2 sensor sockets are made equal, the good ones are massive with high grade steel that will resist the spreading. But this is a great band aid approach for sockets that don't measure up, I have used the same technique on other fasteners, especially nylon flange nuts and such that are used to make liquid flow connections. In those situations the flange nuts stretch when the joint is tightened and will jump threads and never get tight enough to seal the joint. But the hose clamp around the nut will keep it in proper dimension and things work fine then. The old hose clamp sure can be a handy tool!
Really good information. Yes, I've had sensor removal tools to spread as you demonstrated. I'll use this idea next time I'm removing an O2 sensor. Thanks! Using a breaker bar is almost always necessary.
And heat
That tip Worked. Thank you!
Tks for educating !❤
If your set on using the closed end of the wrench, use a molex tool to remove the pins out of the connector. 03:51
Those sensor crow's foot wrenches work pretty well when you use them with an impact like intended
This actually works. Thank you for such a helpful tip
Liked the commentary bro, that was funny. I’m fixing to have to change my o2 sensors thanks for the heads up. 👍✌😀
I like it! Thanks!
I'm an engineer and I approve this message
Cool tip!! Never used this technique. I’ll have to try it out sometime.
What a brilliant simple idea I recently changed my 02 sensor bank one, cheers fella for this tip for next time 👍👍👍👍
Most times you can clean and still use the same sensor.
Sensor in the video is still being used.
I heat up the car and get it warm because I don't have an oxygen and acetylene torch but the night before I work on the car I soaked it with liquid wrench then use the special socket made for it thank God they always come out the liquid wrench the night before I'm warming up the car and using the right tool always gets it out for me
Thanks great video. very useful technique
That’s a really good trick. Thanks!
Great idea. Learned something new today. I usually just cut the 02 sensor with a grinder and put a short 1/2" impact socket to remove. I've had trouble before with these 3/8" adapter because the pressure caused them to snap off. Anyways. Thanks a bunch. Different options is always good. 👌
Just use a pipe wrench
Thanks bro! just did couple of ox sensors this weekend. I has a ox sensor kit and it would just strip unless I used the clamp. I keep the clamp in the os sensor kit now
GREAT IDEA! THANKS, GUY!
Id be more bothered about the state of the exhaust rather than sensor 🤣
Nice work, never had problems using just the special tool but is always good to learn from others.
Thanks for making this video. You can never have too many options in life.
Brilliant idea! Thanks
Before installing the new sensor coat the threads with some anti seize and the next removal there's no problem
This is a good idea however the engineers also thought of this before you so most of your oxygen sensors are barely possible to get to and much less likely to have the room to get more that one finger to them let alone both hands and a hose clamp and screw driver. Usually you can force the wrench over the connector without breaking the connector but usually when it's getting removed it's getting replaced anyways so I cut the wires off and carry on with life. Most of the time heat is the best option in my opinion.
Yup, 6 pt wrench and the propane torch works every time
Quick and right to the point!
This real tequnique helped me I think 2 times at least. It really works like right away it breaks loose. Thanks
I’ve never had to remove exhaust to get a O2 sensor out. Use better quality tool and it won’t slip as easy. They also make a air hammer sensor removing tool for the stubborn ones. In my experience if that doesn’t work which most the time it will a torch will loosen it up.
This also shows why it’s important to use the anti seize when you install one. That’s why it’s included with the sensor when you buy a quality one.
A flare nut wrench works just as well
Great tip genius really never thought of that before but so true!! Thank for sharing your idea
Loved your humour!
Good tip.
But just to clarify.
A P0420 or P0430 is NOT a faulty Oxygen sensor.
The reason is that the upstream & downstream sensors must READ/ SWITCH the SAME to set the codes.
This tells the computer that the converter is NOT converting gases so the downstream sensor read as if a converter is not there.
If one sensor is bad, you will never get a P0420 or P0430 bc the sensors won't read the same
What about an exhaust leak, will that trigger the P0420 code?
GENIUS, about to try this.
Great tip - thanks for posting.
What if you file the tab down and round it a bit so it will go through the closed end of the wrench?
That's something might be worth a try.
They sell a o2 sensor removal kit you warm up the ride and remove the.o2 sensor and usually po420 means a bad catalytic converter
Thanks a lot for sharing this clever method.
You're welcome.
Frickin awesome ! I co9uld have used this tip last week. Simple but not the first thing that came to mind when my wrench opened up. Thank you
Pro tip number two. heat the o2 sensor bung up. The threaded part welded into the exhaust pipe with a torch propane or map work fine. you can also use an electric inductive heater. This also works great on exhaust studs and nuts if you can't get them free without rounding them off or stripping the threads. I would also invest in an thread chaser to clean up the threads after you get the sensor out.
Heat it till it's dull red. Moves right out.
I'm a 34 year tech, I bought the American made snap on tool 25 year's ago. Never broke and made me thousands over the year's. They also make same tool with a handle. If the o2 is bad then cut the wire off and put a snap on impact socket on, problem solved. If you heat the bung to much or incorrectly the threads may come off the bung
Agree - nothing worse than the guy with the $9.99 bucket-o-tools who says he fixes everything.
Tech for 17 years. My $9.99 performance tool o2 sensor socket I bought when I first started wrenching is still my go to and works just fine.
@@peteralessandroni3442 PT tools is one of the very few exceptions to the cheap tool rule. I've never had one fail me. I've got a 30 dollar dedicated flex head wrench for my 02 sensors that has never failed me either.. its done em on my audi, my bmw motorcycle, my f150, and even my jeep. I dont think there is a single reason not to get a well built tool .. they dont deflect when putting tq on em.
This method works! Breaker bar, o2 sensor socket, and pipe clamp. With good leverage, the sensor moves like butter.
Great idea, thanks. I found your exhaust pipe to be quite interesting as well.
I have to agree that's genius. I have a 2001 Corolla with bad post cat O2 sensor. Its plug will allow me to put a 7/8 wrench on. Problem is my wrench is a 12 point and the sensor is frozen- it won't budge even if I hit the wrench with a 3 lb sledge. Even after heat and PB blaster. I'll definitely try your idea.
did it work?
Actually, I decided to use a 6 point box wrench. As the sensor was bad, I just cut the wires off. I also lots lots more heat than my first attempt. Map-pro works very well. I wish I'd bought more sooner.
@@markwest7258 My attempt failed with clamp (stripped O2 nut) so I am trying a 22mm extractor socket this week.
Wrenches made for tubing are what I would use to begin with, that would be the best route to avoid rounding the nut to begin with. Also a little heat before removing will help a lot.
....you mean a pipe wrench?
No I mean a flare nut wrench. Pipe wrench is for threaded pipes.
@@chrispickett3092 ...a flare nut wrench is useless on these.....a pipe wrench is NOT useless on these.....Pro TIP, here....yeah
Not when heated smart one.
Blessings this is the best video on 02 sensors around
Thanks for the tips.
Cut a notch in the closed end of the wrench 🔧 just enough to fit the wires thru,
Just like those sockets have a cut out notch
You can do the same to the closed end of the wrench, use a cuter wheel to do it
It works like a charm
Yes , like the old brake bleeding hack , notched out ring spanner trick
