#1 rookie mistake DIY enthusiasts make on an o2 sensor change: removing the sensor from a manifold/header at ambient temperature. Always preheat the sensor bung, either with a torch or by running the engine until the manifold/header is at operating temperature, unless you enjoy torn knuckles & stripped threads.

@haywire17 6 лет назад

Try this: O2 sensors don't usually "fail" per se (except in the case of an "open heater circuit") - they get "fouled". They won't handle being dropped or banged around, but they ARE made to withstand extreme temperatures, so take advantage of that property... Use a propane torch on the end of that sucker until it glows cherry red. Monitor the output voltage as you take the tip in and out of the flame (I put them in a vise), and when it starts responding rapidly (instead of sluggishly), you have "cleaned and defouled" it. (Narrow-band sensors generate their own voltage when sufficiently warm). Reinstall, and presto.... I make no guarantees (I've had at least one this didn't work on...it stayed sluggish no matter what), but this has worked for me at least 1/2 dozen times over the years, and if the next step is replacing it anyway, what do you have to lose? FWIW, I have had NO LUCK using this procedure on WIDEBAND sensors... And yes, use anti seize to reinstall.

@x-man5056 5 лет назад

To ease removal of O2 sensors; When engine is hot from driving, operating temp, squirt some PB Blaster or other good penetrating oil at the base where the threads are. Let it set for an hour, then remove. If that doesn't work, heat the area around the base of the sensor with a propane touch if you can or a good heat gun and squirt more Penetrating oil. Let it work a while and try again. I've never had to reheat more than twice.

Believe it or not (!) sometimes it helps to try to tighten a stuck bolt/nut/O2 sensor(?) THEN try to loosen it.

@anthonyrybczynski5420 3 года назад

The number one only way that always works to remove a stuck 02 sensor, egt sensors, knox sensors is to have a friend rattle the bung with an air hammer while turning the sensor gently with a wrench. I do this at work every time i get one and it works every time. Obviously you need to be an experienced air hammer operator or be able to use common sense and not ruin the bung, the exhaust or anything else but if you can operate your tools it works.

You don't need no special socket to remove a bad o2 sensor. Just cut the dam old wire off, take a deep socket and hammer it in. If that doesn't work, just break the end off the O2 so you only are left with a nut flush on the pipe. Hammer on a 6 point socket and go to town on that Mfer

@cra2cra226 Год назад

I like it but some are saying they save the old upstream one that's still working and use it as a downstream sensor if one of those ever goes bad. Could save you $50+ but that may not be worth the headache.

@curiosity2314 2 года назад

Very good video on this topic, one note others may have added but thought I would also, use a hose clamp around the O2 sensor to zero out the flex in the socket. May be the difference between an O2 sensor socket working for you or not.

@tonymontana897 2 года назад

I have also heard never to use dielectric grease. If the factory don't use it then why should a DIY person use it ? It's a very confusing topic with many points of view. I think one should keep it simple. Remove the old sensor, apply copper anti seize to the threads of the new sensor, install and tighten, clean the car's female socket end with some electrical contact cleaner, then plug it in. The socket has a very good multi strata rubber seal so no water or dust should ever enter. If you have to add dielectric grease, then just add to the outer part of the socket to form an outer cushion.

@georgiafan6618 5 лет назад

You can heat up the old sensor carefully around its base (threads) where it meets the header or exhaust pipe using an acetylene torch. That will help to back it out safely if it is stuck in there. If you don't have that torch, take your car to a garage and have them do it for you. Coat the sensor liberally with anti-seize being careful not to clog the holes and reinstall. Do scheduled maintenance and that will help avoid this install issue. Have an extra sensor on hand so you have it as they can go out of stock. Good video TY!

Very well done. I would add that the silicone dielectric grease *must* be kept away from the business end of the sensor. Silicone is like cyanide to O2 sensors. I do agree with using dielectric grease in the connector, though. The O2 sensor is a high impedance voltage source, and will not do well if any water finds its way inside the connector. (50 years in electronics)

A tip for breaking out to old sensor. Soak them with wd-40 or liquid wrench or something a couple of times a day for a few days before you change them. The consistent soaking with the heating up and cooling off usually makes a big difference in breaking them out. Also, put an open end wrench on it and wack it with a hammer a few times before trying to break it out.

*@**2:28* Yes, COPPER anti seize is very important- it operates with millivolts- and it needs the best ground connection possible. A _heated_ O2 has a ground for the heater circuit and sensor, so no attention to ground is necessary. I had to edit this 4 year old post, another viewer named WhiteCollarRedneck pointed out my previously incorrect post.

@HUBBABUBBADOOPYDOOP 6 лет назад

That is the main reason copper anti seize was formulated. It's also advisable to use on spark plugs, too. The other advantageous use of it is for exhaust fasteners (manifold nut & bolts, pipe connections, etc.) The old silver stuff (Molybdenum Disulphide) is terrible at conducting electricity, so it's pretty much unused now, but still good for general use.

@MattsShop 6 лет назад

+HUBBABUBBA DOOPYDOOP I can never remember which one, copper or silver is used for what purpose. The silver stuff is a lot more common. I would use the copper stuff on high heat nuts and bolts. You are saying to use it on spark plugs too instead of the silver stuff?

@HUBBABUBBADOOPYDOOP 6 лет назад

Yes. The "silver stuff" contains no Silver. It is basically a slippery mineral (Molybdenum Disulfide) that has very poor conductivity in high heat applications. In comparison- Copper is far superior. en.wikipedia.org/wiki/Molybdenum_disulfide There are reasons why companies do things. Most reputable O2 & AFR sensors come with Copper now.

@MattsShop 6 лет назад

+HUBBABUBBA DOOPYDOOP Wow, thanks for the lesson on anti sieze. I know it's not actually silver, but I didn't know that it has Molybdenum in it. They say aluminum on the packaging. Must be just marketing. Yea, I have noticed that the O2 sensors come with the copper verson. Which kind do you like to use with spark plugs?

@michael47lamb 4 года назад

Nice video However instead of running out to buy new O2 sensors, everyone should try to clean them by burning off the carbon and other deposits O2's collect over time. Easy to do with a bench vise and a propane torch. Simply carefully put the O2 sensor in the vise by the wrench flats, sensor end upwards, be very careful of the wires! Then heat up the end with the torch until the end is GLOWING bright red. Once it is a nice more or less even red (including the parts inside the slotted holes (peek in there and try to get that red as possible too). Then let it all cool down naturally and reinstall. (DO NOT use any sort of water or chemical cleaning on these!) Chemicals dont work anyway for this, and can leave more deposits as well! I do the Burn thing when I have a little time to kill and it works 90% of the time too! Save you a bunch of cash. You cant really hurt the O2 sensor doing this so dont be afraid, sensors like 600F and more in normal operation, the heat is what keeps them clean. Stop and start trips in cold weather is what makes them get dirty, also spraying chemicals on them! Of course eventually the platinum catalyst in them does wear away, but the burn cleaning is worth a try at least once (or twice sometimes.)

@Born-Again-Warrior Год назад

Thank you for a very thorough break down on how to attack replacing them, particularly all the caveats involved.

@scottfirman 6 лет назад

If you already know your 02 sensors are shot and already have the new ones,you can just cut the old cables and use a large enough deep well socket,no special socket needed. You can use a regular wrench to put the new 02 sensor in,once you finally get the impossibly tight 02 sensor out. A cheap 02 split socket for removing the 02 sensor will flex,slipping on the shoulder of the 02. Making a home made socket by noching an old socket will also result in slipping.

@MattsShop 6 лет назад

Yea, someone else mentioned this too. It is a great idea if the split sockets keep slipping and flexing. Although, it might not be the sensor that's the problem and once you cut the old one you no longer have a spare.

@willsheehan2975 6 лет назад

You can add a pipe clamp to keep it from slipping if you are trying to remove it to get it out of the way for example and don't want to cut the cord

@scottfirman 6 лет назад

Walter Sopchak Could you please explain how you do that? I cannot fathom how a pipe clamp can keep one from slipping. I sadly sold my socket designed for removing those...I still dont know what I was thinking. Generally, you always test the 02 sensor anyways before cutting the cord. Using a simple multimeter can tell you if it is bad. Testing the wire to the unit can be done with a 12volt headlight from a garden tractor. Use the bulb holder and solder wires with alligator clips to the ends of the connectors. You dont need a fancy oscilloscope to test an 02 sensor. if it doesnt heat up, its dead. if it showes open circuit, its dead, yes its that simple.

@scottfirman 6 лет назад

Matt's Shop You would test the 02 sensor BEFORE cutting the cord. It is so simple to test them. An open ground,dead. if it doesnt heat up, dead, use a 12volt garden tractor bulb holder with alligator wires to test the wires to the 02 sensor first. 90 percent of 02 failures is corroded wires. They cannot be repaired, ever. The wires are special, like a toaster wire. I never chop wires on anything until I know its dead.

@galtha58-trannybear14 3 года назад

Did you try a little heat around the outside of where the O2 sensor screws in when you removed the old one? Sometimes a bit of heat from a propane torch or something similar will make a job like that a lot easier. You have to be careful, of course, same as anytime would use a torch. Not to burn yourself, start something on fire or harm any other parts.

@marnieravitch1371 2 года назад

I'm not a mechanic and have a dumb question. If you're replacing the old O2, would it be possible just to cut the wire off and use a regular impact socket and wrench on it to remove it?

@glennwirth7334 19 дней назад

But then, how do you torque it back on if you can’t get a regular socket over the wire

@Deucealive75 6 лет назад

I have changed out multiple o2's out over the years and never had a problem. I use a cut in half 7/8 wrench. Heat half of the bung red hot and use the box end of the wrench and tap it loose with a hammer. Tighten the new one down with the open end. Doesn't even have to be that tight. Pretty easy.

@MattsShop 6 лет назад

Good idea to hit a cut in half wrench with a hammer. Could even use a air hammer if you have one.

@Deucealive75 6 лет назад

Yes. Once the wrench is on it's usually just one hit to break it free. The shorter cut in half wrench helps because most often there is not enough room for a long wrench. The heat with a torch is the biggest help.

@MattsShop 6 лет назад

Yea, that's a good idea to cut it in half for more room.

When taking them out, I just cut the wire and use a regular socket. Those special sockets are for putting the in, not taking them out. I had one of those sockets keep stretching open causing it to skip. Thats when I figured out it doesnt matter on the old one if you chop the wire anyways. Yes a breaker bar for sure! When you have to take the manifold off because you cannot get it out, that ruins your day.

@metalhalide4043 4 года назад

I always use my MAP gas torch to remove. Spray some PB Blasters on em, wait a while. Try to crank on em, if they don’t come off, grab a MAP gas torch and heat up The O2 sensors. They’ll break off after you do that. I just did this today on my new vehicle.

Keep in mind it's directly screwed into the exhaust just off the exhaust manifolds. So everytime you drive it, it heats up and cools off and rusts. Basically welding itself into place. So anything over 1,000 miles is going to be tough to get out with just a wrench.

@johnlafrieda5160 6 лет назад

Chris Chiampo: I have been a mechanic for more then 30 years and in the Retail parts business for more then 6. I would not use Vaseline for anything other then a sore. Dielectric Grease is formulated to give you better voltage "Pass Through" to the circuits then Vaseline can. Also, dielectric grease will last longer and being a "grease" it lubricates the electronic connectors. keeping them from rusting for a longer period of time. By the way, good video.

@MattsShop 6 лет назад

+John La Frieda You heard the man, haha. Yea, I would always use the right product for the job. Saying vaseline is the same as dielectric grease is like saying 10W-30 is the same as 140W oil. It's all oil right?

@johnlafrieda5160 6 лет назад

LOL.... Absolutely. One never wants to turn to something "similar" because you may save a few pennies. "Penny wise is dollar foolish." Save a few cents now, spend allot of bucks later to correct your a problem that YOU caused. After all, we all know that rust FOLLOWS an electric current, causing rust to follow the wire loom under the insulation. IE: Battery Corrosion.

I work for a well known company that makes aerial lifts. We have more problems from using dielectric grease than we would have had using none at all. I believe assembly quit using it all together. It's not meant for the contacts but more for where the plug seals together. Dielectric grease is not very conductive surprising as that sounds. Mabe for the edge of the plug but not the contacts.

@giannivalenza1751 4 года назад

Many O2 sensors (zyrconium based) works comparing INSIDE gas with OUTSIDE athmosphere. The opening for the outside side of the sensorr is the plastic isolator of the wires, in particular the opening in that external isolator near the plug. Putting any substance on the plug CAN affect and contaminate the sensor leading to wrong readings.... So be careful with that dieletric grease!

@johngreen6643 6 лет назад

Doesn't matter if you touch the end of the sensor or not, the actual reactive sensor part of it is protected inside of it. So as long as you don't dip it in goop or cake it with crap then it'll be fine. And like the many comments say, heat up the area where the sensor threads into. Whether it's with a torch or running the car for a few minutes it'll help considerably. Also changing just the one causing the code is fine but if you have the bux & like a good running ride then it doesn't hurt to change them all. Work smarter not harder.

@MattsShop 6 лет назад

+john green I agree with working smarter not harder, but I still think it's best to not touch the sensor. Why touch it? Theres a reson they tell you not to touch it. It's a rather sensitive and expensive part. What happens if a piece of dirt or hair gets down into the sensor's end. My guess is that it would mess it up.
