Best Technique For Removing Stuck O2 Sensors - Don't Gall The Threads!

[@kevincameron1163]

2016 Ford Expedition. I drove the truck. Got it nice and hot. Tried the O2 sensor. Would not budge. I used deep creep and propane torch. Would not budge. Used a hammer pounding on the end of a 22mm combination wrench. Nope. It started slipping. Rounding over the nut. I was panicking. Nothing was working. I was about to get a Dremel and cut off the O2 sensor and then drill it out or something I don’t know. Just before I started cutting I remembered my dad talked about using the two wrench system. Link two wrenches together for extra leverage. I tried that and bam💥 !!!! Slowly that O2 started to crack loose. I was so happy. Dad always knows best. He always used to say “Leverage is your friend”. I love my dad. He’s a smart man. Taught me everything I know.

[@LTHawk]

If the nut is rounded leverage isn't going to do shit.

[@mach4x92]

This technique saved me the trip to a mechanic for a 2000 F150 upstream O2 sensor. Thank you for the advice!

[@markim9728]

how do you link the two wrenches together?

[@psavel274]

The double wrench technique works great when there's only enough room for an open end wrench especially. Been doing it for over 25 years. If the fastener is rounding off leverage could be worse for it than anything, you need to break the bond of rust in between the threads which is why rattling it is the best bet until you get it broken free enough to work it back and forth

[@metrork1]

@@LTHawk You might have to resort to a pipe wrench of appropriate size.

[@dbfcrell8300]

I know this is dumb, but being able to have the vehicle over head is EVERYTHING. Trust me, I know cause I'm in the middle of removing a stuck downstream O2 sensor and I'm on the floor with the sensor 6" above my face and a flashlight in my mouth. No room to work makes the job seriously tougher.

Went to sea for 35 years working in the engineroom. I’ve probably used 20 pounds of beeswax in my lifetime. Beeswax has a higher melting point and won’t flash. Heat up the joint and melt the beeswax into it. Heat cycle it several times if time allows and bang on it. He’s right, it’s the hard shock that breaks it loose. Use the shortest wrench you have to hammer on. He’s also very right about working back and forth once it’s loose while flushing it with penetrating oil. I’ve seen nubies get a bolt loose only to seize it the very next half turn. Great video! Thanks for posting.

[@cowboy1833]

The best way to get any stuck bolt loose is number one , heat it up good I'm talking orange hot. Two, take a garden hose and cool it as fast as you can , when its cold it will be next to finger tight , Works 100% of the time. Been turning wrenches for 25 years a old man taught me this trick . Best thing I ever learned in a shop. Its amazing how well it works.

What that also does is causes thermal expansion and contraction. We're talking thousands of an inch, but, you could cause warpage and damage. That being said. If all else fails, do what works to get er done

[@TheRoadhammer379]

We called it heat and shock when I worked for a mining company. We had giant haul trucks with 1-7/8" lug studs, we'd heat the stubborn ones and hit with a hose that pumped ice water. Usually took one cycle and they'd come off. We always replaced the lug nuts but couldn't damage the studs, and no... we never experienced warpage.

In some cases you will have damaged threads, just chase them or if really gone, TIME-SERTS work really great. Carry On

[@harlandlippold5220]

Thanks Chris! I like the ideas, particularly the air-chisel-pickle-fork on the wrench: easier than the hammer swing. I'm a car restorer by trade, and engineer by education. All your observations on the use of lubricants are excellent. I want to mention the trick I use for seized/corroded fasteners in-general: Since heating expands metal, and cooling contracts it, the goal is always to heat the outer portion while cooling the inner. As the gap between them grows, you want the penetrant/lubricant (everyone has their favorite: I like Kroil.) to get pulled into that gap. I use a propane torch to heat the nut/boss/bung. When I get the oil smoking, I use a can of office -duster, upside down, on the bolt/stud/sensor. (THIS IS POTENTIALLY HAZARDOUS! Upside-down, the office duster will emit liquid at cryogenic temperatures, similar to liquid nitrogen. Wear eye protection and long gloves!) Get the sensor frosty, and add your penetrant at the thread interface. NOW do everything Chris shows! In some cases, you can win by reversing this idea: When bolts are broken off inside a blind hole, oil the threads in the hole to prevent adhesion. Then, use a center punch followed by a sharp drill tip to clean the center of the offending bolt fragment. (Don't drill it out, just prep a spot to start the weld.) Using a wire-feed welder, strike an arc on the bolt remnant, and fill the hole to the surface. Now hold a nut in place with a cheap wrench, and weld the inside of the nut to the previous weld. The bolt tries to expand, but is contained by the surrounding colder material, so it can only mold itself more uniformly to the hole (and thus decrease the pressure at the bound points). Hose everything down with penetrant, and take-five. When you come back, the previously glowing bolt fragment has cooled and contracted, by transferring it's heat to the surrounding material, which has now expanded. Chances are excellent you can put a wrench on the nut (now bolt-head) and turn the whole thing out in one piece. Sometimes, I have to repeat a couple times. At worst, I'm back to drilling it out, but I've annealed the metal by heating it and letting it cool slowly, so it drills easier. Win-win. I'm subscribing, because there is no substitute for experience, and production mechanics like Chris get more experience in a week than I get in a year.

They are thick and crude, pretty awful for actual brake lines etc. But they go up to 24 mm, and the 22 mm is a perfect fit for many O2 sensors. Being so thick, and providing contact on 5 flats, they work really well for this job. Honestly, it's about the only thing I have ever used them for, but it was still $8 well spent!

After using penetrating fluid, suggest getting a can of liquid butane lighter fluid, holding the can upside down and pressing nozzle against threads it to release liquid butane into the threads. The liquid butane will help carry the penetrating fluid deeper. It will also get the part very cold which has effect similar to using a torch but is contraction vs expansion.

[@LetricShave]

If you have to go with a common combination wrench, use a 6 point box end wrench instead of a12 point, it will lessen your chances of rounding off the sensor. Never rotate the sensor with the wiring harness connected. You’ll put at least 5 full turns in and twist up your wiring to the point of possibly damaging it. One viewer mentioned letting the exhaust system warm up from running the engine. This is also very effective and will allow your penetrant to flow better into the threads.

[@NoNonsenseKnowHow]

Is there is enough length on The Wire there is no sense in going to disconnect it inside of the vehicle. I've changed several hundred sensors and never had an issue. Of course there is a point where you would do damage by twisting the wires to tight. I always make sure to count the rotations off and clock the sensor properly before reinstalling. but yes you're right that you should disconnect the sensor generally. It's just not always practical depending on where the location of the connector is

[@NoNonsenseKnowHow]

And yes six-point greater than 12 point for grip

[@garypeterson9083]

As a side note, be careful not to use too much antisieze. If it gets on the sensor area it will contaminate it.

Nice! Sounds like a good method! I forgot to mention about breaking the sensor to get a shallow socket on there. Ill have to try dousing in the future

[@daboo7725]

I use copper seize on all exhaust work, seems to do better then regular grey anti seize.

[@NoNonsenseKnowHow]

You're right. It is better. They just happen only order the gray Antiseize at my work.

[@lukemartin7029]

Just replaced stuck upstream O2 sensor on 2014 Escape. Used your vibration technique. Sprayed penitrating fluid on using cordless impact on lowest setting to vibrate it. Spryed a little more penitrating fluid. Waited 5 minutes set impact to next power level and it came right out.

Dude just wanted to say I really liked this video. Like, most mechanic channels are some dude with no personality but you kinda killed it. And I loved the go pro angle. Usually people are holding phones in awkward places and it’s not good but this was kind of thing everybody should be doing. Your personality is cool and it was just a good video. I would watch the sh!t out of a channel that was all videos like this 👊🏻👊🏻

Hey Josh thanks so much for the comment and feedback. Really appreciate you checking the video out. Thanks man!

[@the1andonly]

I've got a 1989 Chevy I fixed up and it runs good for the most part. But the fuel economy isn't great and the exhaust smells like gas, especially when it's cold. I haven't changed the oxygen sensor yet and was going to hold off until it's warmer, but will do it this weekend and your video helps me be better prepared. This sensor may be really old. No clue 🤔

[@rohanpatel4863]

A trick that always worked for me is; heating up seized bolt or sensor really hot, cool the area down with Brake oil drops; because as the brake oil cools down the area, the air inside the threads will create a vacuum and suck the brake oil inside. It works every time.

[@par6769]

Thank you for the tips, I had an O2 sensor initially break loose but then wouldn't go any further. Your back-and-forth method while adding penetrant would perfect.

[@colefisch931]

I actually use anti-seize all the time on mold components that I'm drilling/tapping when I absolutely can not break a tap/drill bit.

[@buckalbert5628]

The genius take home for me was spraying the O2 sensors with rust penetrating spray, in my case WD40. I had 4 sensors on a 2012 Jeep Wrangler and the downstream sensor on the passenger side was NOT budging. I soaked all 4 and ran the engine until it was hot. I let it cool and repeated this 3 times and then let it set over night. ALL 4 broke free the next day. THANKS for a great tip, you probably saved me around $600 in mechanic labor!

[@dtnel]

Don't remove the sensor until you've tested so you don't take a chance of ruining it unless you're replacing them all anyways. Use OEM when possible on O2 sensors as it's been shown that aftermarket isn't always the answer.

[@jimmykulik3438]

Changed one in my 15 equinox 2.4 did it from below with extensions and the 1/2 air gun it was brutally tight. It started to rotate tried going back and forth but eventually had to just keep the air gun rapping until it was out the internals of the sensor broke off inside the cat, and it did some thread damage but overall the new one threaded in and l just tightened it with a 7/8 box end l grinded so l could slide over the wires it did go in a it did tighten right up so really happy left the internal pieces that broke off inside the cat probably sitting on the cat screen 🤣but all good no service light and pulling 8 liters to 100 k. On fuel monitor improvements in fuel economy was over 15%! I'm getting exactly what gm indicates I should be actually gm said 8.2 liters for 100 kilometers km at 8 liters for 100 kilometers 👍

[@mikemoffett4827]

as a forty- plus year survivor of the exhaust industry; Let me share with you a tip I learned a long time ago. You will be sceptic at first, but give it a try- You will be AMAZED! Here goes; the tip is -BRAKE FLUID! That's right- brake fluid! Simply soak the sensor with a little brake fluid, let it sit a few, then work it back and forth. VIOLA! It really is like magic! Give it a try- You will be amazed!

[@afisemenaborevlaka48]

Thanks for the tip. Less messy than Transmission Fluid and Acetone combo.

[@ridgerunner106]

Try some plain ole green anti freeze. Brake fluid works but if you pour it on something heated with a flame and it steams, fumes will knock you down.

[@mannypuerta5086]

The previously mentioned ATF and acetone or my go to: Kroil. Otherwise, heat and vibration.

[@johnreisig3017]

I'm Johnny Muffler I have 40 plus years of doing exhaust work Getting a O2 Sensor out I mostly use a pipe wrench and a pipe on the end If I'm changing the exhaust I cut the pipe close to the sensor and spray pb blast from the inside of the sensor as well as a little on the outside This helps the threads from locking up and stripping them If you have one that's rusted to no end use carb cleaner 2 plus 2 on the outside and than freeze out This will pemastrate thru the rust better than anything The carb cleaner burns the rust away the freeze off is the best in a rusted situation If you have to use heat only heat up half of the area around the O2 sensor This prevents the threads from stripping due to the heat I hope this helps and Goodluck as always Johnny Muffler No Muff too Tuff

I need to replace my O2 sensor on my 2005 Mercury Grand Marquis. Usually I will use PB Blaster to loosen up the threads.

[@skyartrc8286]

The PB blaster is the best, and the way to go.

[@haditwithwork]

I USED to go to PBlaster whenever I had to loosen a nut or bolt but after running into fasteners that wouldn't budge with PBlaster, I found an age-old formula that does the job much better: 50% ATF (Automatic Transmission Fluid) and 50% acetone. MUCH better than anything else I've tried. I shared this tip with a few friends that had similar troubles removing stuck bolts and they totally agree. Give it a try. Good luck.

[@kellyconstenius676]

In Rust country. The fire wrench and the air hammer are your friends.

[@stuntgirl56-therachelvande24]

thanks Chris, I usually do the spray a lot with really great penetrant and do the week or two vibration drive. In addition, after the soak, I try to put a tiny extra Tighten if really stuck and I use a 1/2" CP air impact on everything, except dash bulbs. I have extensions and wobbly sockets that allow me to take parts off from across the yard but remember every extension reduces the amount of torque delivered due to the twist of the metal and loss of power transfer through the steel, good steel, bad or soft steel will flex too much. I use 6 point socket or wrench on stubborn pieces and stud removers for items that will be replaced, take care, and remember; gloves, seat covers, floor protectors and steering wheel covers. You do not want anyone to know you have been there, and leaning on the paper thin 'beer can' fenders is good if you plan on opening a body shop, stuntgirl

[@scottfirman]

I learned all that the first time I had to replace one. Chopping the wires and using a regular socket works.Those split sockets are only good for installing, not removing. Galling the threads then thinking the new O2 will fix it, nope. It just ruins the new sensor.

[@cooperparts]

Repair with a plug chaser works most of the times

[@bsimpson6204]

You are absolutely right, penetrator will not get in until you crack the seal. If it goes tight, lube it and screw it back in, in-out, in-out and slowly work it out.
