Hi guys here's a DIY guide on how to clean your injector nozzles if they're clogged or if you simply want to add this method in your routine maintenance. We recommend cleaning the nozzles every 100,000kms and while you're at it, replace the injector O-rings and Copper washers with new ones as well. It's also best to clean the injector seats on the cylinder head before you put the injectors back in. There are injector seat cutter tools which you can purchase online.
Remember: This is not a certain fix on faulty injectors. If your injector is stuck open / closed, doesn't fire or actuate when energized, excessive back leakage, It's best to consult a professional.

Best film I've seen on these injectors. Exactly what ive got to do, so thanks from here in Cornwall 🇬🇧
Thanks! :)
The exposed procedure is wrong.
@@PopaAlexandru. why is that?
@@felipeuk12 For example, the lack of a basket in the ultrasonic bath... one error is enough for the whole process to be compromised. And there is at least one more error: the use of thread brake.
@@PopaAlexandru. well spotted 👍
One tip from a guy who's job it is to actually recondition these injectors...please don't put loctite on the nozzle threads! When I inevitably get your injectors to properly rebuild, it sure makes it a lot easier when the nut comes off.
best filming on injectors. No BS no Nonsense. straight to work. satisfying as hell. Great job @BTD Garage
Thank you :)
This video by itself gives us DIYers the Balls to do these, "Super Technical", "Garage Equipment Only", "Mortgage Expensive", jobs ourselves. SUPERB video!
Thanks!
Please be careful. I absolutely don't want to discourage anybody from fixing their own stuff, but I own an engine machine shop and I rebuild engines for a living. I have to fix quite a few engines their owners destroyed with home-built injectors. If you have an ancient cast iron boat anchor, you can get away with a hobby botch job. But when it comes to direct injection high performance engines you will melt your pistons in a blink of an eye if you mix up shims or plungers or if you install collars backwards.
Washing up bowl and wifes Vibrator works just as well. If you dont have access to Ultrasonic Cleaner..
Enjoyed the vid mate,, thanks for taking the time to make it. 😀👍👍
Soaking in solvent overnight cleans the internal parts. The tip and screw cap will hardly be touched.
A strong solution of caustic soda (lye) NaOH will burn out carbon but won't touch steel. It will dissolve aluminium, zinc etc (bad for brass) but these are not present in the nozzle area.
Great video not only sharing knowledge but giving others the ability to eat 👍
And someone told me those injectors can’t be opened, told him they were assembled at some point so obviously they can be opened and boom here is the video that’ll save me thousands of Namibian dollars in the future.
Great tutorial, well prepared, well shot - with the camera focus on the interesting elements, not trying to adapt all the time.
Thanks for the recording quality !
Thank you!
Loved the filming and the text but not the musak.
Next time, please speak (narrate) the instructions along with the written text.

Another challenge in my life to do this injector cleaner. Tq
If your copper washers get stuck down the bore I welded a thin stud extractor onto a thin extension and it came out immediately after hours of scratching my head. Very useful video. Thanks.
👍 Great video.. Very effectively shot with clarity. The best part is no bla bla.. Man you have nailed it.. The best ever video on the injectors. Keep up the great work..💐🌷
Thank you! :)

Thats a super video, on cleaning of diesel Injectors. Very educational!!
Glad you liked it!
Awesome man! And that is probably the best instructional video I’ve seen on any topic! And I have the confidence now to tackle it. Thank you very much!
Thanks!
Fantastic... no bla bla bla.... efficient and really perfect, thanks a lot
Thanks!
Simply The Best ! Thank You For Sharing !
We was think this job will do by big factory only.small shop at home with good skill we can do.great thanks for this video to educated us
Excellent tuto. Many thanks 👍👍👌👌.
Now ready to do the same with my injectors (and then, as David Elliot said, recut the surface of one seat as heath and flashes passed the copper ring 🥴🥴).
Tribute to BTD.
Thanks! :)
I am not sure i will do this but if they are Sticking after new seals i will, Very cool vid my Guy. Also you got the steady Hands of a surgeon.
Thanks brother!
Ang galing mo talaga sir. Ipapa rebuild ko jan ang turbocharger ko.
Hi ! My 207 which has 400,000 km and which still has its 4 original injectors, I will do to it what you did (except that I will also unscrew the upper part in order to immerse the injector completely (electrical part removed). I I think they will get a new lease of life. Then I will do the same thing with my original turbo. Thanks for your video! :)
Nice video thanks 👍 keep up with your great work
Very good tutorial video👍
No doubt you are a Pro Liked the quality and standards
Thank you
best on RUclips
Your the best, very very good video.
Mate, I’m stuck on a rural town and can’t get anyone here to do this job, after watching your video I’m going to give it a go, thank you
hey mate, interested how did you manage? all went to plan? (never mind the background trap-beatz :)
@@paterix79 car is running perfect now, I only clean the injectors externally, didn’t pull them apart as can’t get the recalibrated where I live, all the copper washers replaced, o rings too and used new stretch bolts, car is purring now
Very helpful. Thank you.
Good job man
5:18 Perfect atomization of the nozzle.
Because of this video I started cleaning injectors really a clear video this is how to take everything apart and luckily earn good money with it!!! still looking into revision where I can find parts so far never had any complaints and no I'm not a garage I just do this at home as at work
Thank you for the video
Good man I like the attitude
Where do u get your parts?
Carefully examine the injector seats pithing the the cylinder head and recut the surface if necessary. Extracting a stuck injector (caused by gas blowing past the copper washer) can be a real struggle.
Ya me suscribí porque quiero limpiar mis inyectores
Great Work mate.
I've been told it's not good for the ultrasonic cleaner for items to be touching the bottom of the tank. That's why they come with a basket.
Yep that’s right :) I find that true for heavier parts. For lighter pieces like these, I think we’re okay
Nice video... Many thanks !!!
Thanks!
Great video. Interesting that these are from a Hyundai and use a shim. My 2014 328d BMW has what looks like a larger spring and no shims. I just cleaned mine because I got a fault code for my #3 injector. BMW ISTA says throw away and replace with new injector! Well, after cleaning all 4 injectors nozzles, swapping #3 & #4 injector cylinders, reprogramming the computer, and clearing the codes, the fault has not come back and the car runs great. This is definitely a great practice to add to your maintenance schedule. I'm just wondering why my original injectors lasted 130,000 miles ( and failed due to a bad CP4 high pressure fuel pump) while my Bosch replacements got clogged after 1 year of service? Bad fuel? Hotshots additive? Towing 3,000 pounds of wood flooring?
Thank you for the video
Excellent thank you
nice work 💪
Great tutorial!👌🏻 after I did this on my Volvo v50 2.0D (Siemens injectors) sometimes it feels like the engine is running on 3 cylinders or an imbalance around 1000 rpm
You can feel the power increase and it’s running smoother! No horse powers lost but still got this problem:(
Update: 1 injector got stuck now after ultrasonic clean probably was the injector before already not healthy replacing now for a new one.
Never open an siemens injector if you dont have that special device to calibrate the injector.
@@crss085 Calibrate via OBDII or do you mean mechanically? Like internal chims etc?
@@daniellenner813 Siemens / Continental injectors have a very small gap set between the injector solenoid and body, this gap is measured in micrometers, for your injector it is 0.3µm ± 1.3µm. You should never take off the soloenoid from a continental injector unless you have tools to measure this gap (I use an Opensystems Megatester V4). As for opening the nozzle side, you will change how the injector works ever so slightly meaning your calibration code will no longer be valid, however sometimes you can get away with this depending on how worn everything is.
Awesome thanks!
I’ll start a business out of this, thank you.
Good work
Thanks!
Excellent job... can you do this same type of video with Yanmar 6LPA?! Thanks!
I love the video, that's exactly what I was looking for. thank you for such all around beautiful video. Questions: what kind of ultrasonic liquid did you use? where can I find the torque specs for my Bosch injector? TIA
Good and quality job 👍
Thanks!
It works for nothing, that is, it cleans the injectors but at the same time induces premature wear.
Great help. I'm going to try do the same. But I only have car cleaner instead of the sonic cleaning. Would it be helpful if I unscrew the top part off as well to flush the car spray in there too?
Great vid, did you ever do an injector top end strip down?
Very useful video. I've just done my first injector but it only had the bottom shim. Is that normal?
Great film. Just what i need to know for my fiat Qubo 1.3 multijet. 50FT is about 68Nm?
One of the best vids on YT on this topic - and you even include the 50 Ft Lbs torque value! Thanks!
Unfortunately the music was so annoying I shot my dog. What do I tell my kids now?
You tell the kids, “I’m sorry I couldn’t figure out how to operate a mute button, and when trying to shoot myself in the face, the bullet ricocheted off the mirror, and hit the dog.

Hi, great video very clear,please may l ask was the cleaning solution demineralised water?
Great video😊 What power was the ultrasonic cleaner? Forexample 30w or 50w? And what liquid did you use?
Thanks again
very good video, what happens when neither of the 2 injector valves come out nor with our sound, was the problem due to water entry?
Great video, what solution do you use in the ultrasonic?
Excellent. Are the shims ok either way up?
Bello il video complimenti per la spiegazione ma una domanda dopo che sono stati puliti iniettori sono Pronto a mettere apposto o bisogna fare qualche regolazione così ho sentito grazie sei rispondi
Absolutely good performing ! ! ! At what values of the injectors should we start to worry? My one is Audi A6 C7 3.0 dti 204 HP and one of the Injector reading is 0.70 mg . 1 Cyl - 0.7 2 Cyl -0.33 3- cyl 0.13 4 Cyl -0.30 5 Cyl -0.4 6 Cyl -0.10 Mg . Do I have to remove the number 1 injector for cleaning or is there a chance it can be cleaned with a carbon cleaner
It was very relaxing and informative, Thank you. Greetings from Turkey
Thank you!

I love the song :D
After cleaning, do you have to calibrate injectors wen putting em back in?
Please your information - what minimum power in Watts and frequency in kHz
must an ultrasonic cleaner have to reliably clean the injection valves, nozzles ?
Thank you for your answer in advance.
What solution is in the bath? And what's the liquid are the parts in for assembly? Thanks
Отличная работа. Молодец!
BTD Garage...... You, Sir..., are a Fking Gentleman!
Cool base beat as the back ground.
Do the process is the same for high pressure diesel injectors, like Bosch using in VW group CRCA 3.0 TDI engine?
When new injectors are fitted do they need coding on 2010 volvo xc90 diesel
how did they work i feel like putting it on the vice like that can allow the body to twist/ warp the two flat spots is where I would grab it
GREAT GREAT VIDEO!!!!! Probably the best on You Tube! Not doubting you, but what is your source for the 50 ft lbs torque to reinstall the nozzle to base injector? thx much!
Got it from a bosch repair manual :)
Which type of liquid u used in ultrasound cleaner?
Does this help cure the zero quantity adaptation faults like in BMW's?
Does it need calibration or something after this cleaning? I want to do this process at home at my Opel 1.9 cdti .
This is just too good. I have problem with injectors, after i press gas pedal little bit further engine start shaking and almost turning off. When i connect diagnostic i see that 3injectors parameters are going crazy like 4.5-5mg and normal is like 0-1.5mg+/-. I cleaned injectors like this and now car is working perfectly, on diagnostic it shows 0.1-0.2mg.
What kind solution do you use. thank you
Hello, thank you for this great video. What kind of ultrasonic solution do you recommand?
Hi there are a number of ultrasonic solutions that you can purchase online. Best to use automotive parts specific which is alloy safe
Brilliant video/tutorial, can you tell me how many jets should come out of the injector when the all holes are clear?
Depends on injector, at least 5
What solution is best for cleaning diesel injectors?
Should the injector body not be cleaned as well? Should this resolve noisy injectors on a toyota 1kd engine? Mine sounds like it has a massive diesel knock while driving, 200000km
For some reason my wife doesn't like me using her jewellery cleaner for this.
Se smonto solo il polverizzatore iniettore si stara? O posso pulirlo tranquillamente e poi rimontare il tutto?
What is the Assembly torque?
I have a question my needle doesn't want to go back. During disassembly it came out very easy now it seize right at the begining. I put the head back for another 30 minutes of ultrasonic cleaning hoping that there is a small dirt. But still doesn't go in. Would it be a problem if I force it? Does this need to be moving once it's assembled ?
As you answered the question about taking it to get them calibrated, would I need to know the number codes of 123&4 or does machine find them thanks and great vid tutorial
The machine will generate new codes for your injector. If in case you're buying a new set, use the codes located on top of each injectors. Thanks!
Could I slip in a DLC needle in the reassembly ?
How effective are LIQUI MOLY injector cleaners if used every 3-6 months?
Really well instructed video, what type of ultrasonic cleaner machine do you use and what solution do you use for cleaning.
Thanks

Hi! Got the tank from ebay. Says it has 50w u/s power, 40khz frequency and a 100w heating power at the back. Not sure if it’s really accurate though. Regarding the ultrasonic solution, it’s a custom mix we get from a local supplier here in ph. You can find a lot of them online, just get the ones that are aluminum safe. Thanks for watching :)
I'm looking for one too.
Allen Dale ultrasonics in the UK have all sorts. I'm going to get a small one. 50 quid. 🇮🇪
nice beat savage
Do the injector work properly after
Repair
I have an issue with the injector of my Volkswagen diesel car
Should I go for repair or replacement
What temperature did you se the cleaner to
Hi boss,I have to say a mega video one of the best on the subject of general overhaul of mag-controlled injectors. My question is which threadlocker (medium strength / high strength / heat resistance) do you use? The usual products are resistant up to 300 degrees Celsius - because the temperatures in the combustion chamber are around 900 degrees Celsius! I would be very pleased to receive an answer ... Many greetings
While the combustion chamber temperatures are 900C, the walls of the cylinder aren't that hot, and things further back are even cooler as coolant channels run by them. I'd say 300C sounds a little low for an engine, but it's probably fine, or rather, if your injectors are 300C then you probably have bigger problems than the type of lock-tite you used, that's really really hot.
Blue threadlock usually means standard performance stuff. Running temperature will be the same as the engine coolant so nothing fancy needed.
What are the Torque settings
Nm
Please

What is an Ultrasonic? How it works? Can you explaine? And how long time need to wash injectors? One hour, two??
What the torque for coblver injector??
Hey if I will use 68mn on it will it not be too tight? As I can’t get exactly to 67.79
Excellent ❤️🛠️🔥🦅🤝🙏🌅🚨➡️😱
Can you the same for Ford Rangers?
I worked in a factory making injectors for ,11 years and can tell you that its impossible to do the job properly at home. Yes you can strip and clean them but you cant reset opening pressure which WILL change as soon as you dismantle the injector, you cant check the spray pattern properly and you cant check wetseat or backleak time. You need very special very high pressure expensive equipment to do any of that.
Bullshit.
So should I go and buy new injectors for my smoky ford 3600
I believe with a common rail system, you are using the electrical connector to open the injector. Furthermore, the PCM can smooth out idle pulses by watching the change in rpm as each injector is fired. During acceleration, the smoothing doesn't matter anymore and the watches other inputs such as rail pressure, boost pressure and the air fuel ratio at the exhaust plus temperatures. Modern Diesel design and computer control systems allow for fine adjustments. Due to manufacturing variations, auto makers have several programs to fix injector imbalances on all gas and diesel engines.
Cleaning the injectors at home will improve their flow and spray pattern. The tip does wear over time allowing more fuel to flow than set at the factory but the automakers have a mileage adjustment as well in their fuel calculation.
I work in the trade since the late 1970s and I never ever saw the opening pressure of an injector change drastically after dis- and reassembly. If you put the tips in the same injector body they came out of, you will be fine in 99,9% of the cases. I also think it is much better to drive with a cleaned injector which is a few bars off than drive with a carboned up and leaking one.
The best way after cleaning is just put injector on bosch maschine to generate new ima code. Thats all. Then injector can working totaly properly. Of course when is not damaged. New ima is ~20$ pro pice
