HOW TO CLEAN BOSCH INJECTOR NOZZLES LIKE A PRO | 2021 ULTRASONIC CLEANING DIY 

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 👍

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.

Thank you :)

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.

Thank you!

Loved the filming and the text but not the musak. Next time, please speak (narrate) the instructions along with the written text.

Good man I like the attitude

Thank you! :)

We are manufacturer specialized in auto and marine diesel engine parts since 1952. Our main parts are EURO II system: plunger, nozzle , delivery valves, head rotors, repair kits, etc. Common rail system: Injector complete and injector spare parts for CATERPILLAR, DENSO, DELPHI , BOSCH, SIMENS, CUMMINS, etc. If you have any inquiries, pls do not hesitate to contact me.

Thanks!

Glad you liked it!

Thanks!

Thanks brother!

Thanks! :)

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

Yep that’s right :) I find that true for heavier parts. For lighter pieces like these, I think we’re okay

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.

​@@cristi2886 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.

Thank you

Hi there are a number of ultrasonic solutions that you can purchase online. Best to use automotive parts specific which is alloy safe

Got it from a bosch repair manual :)

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. 🇮🇪

It is 80Nm for the old indirect injection ones and 45Nm (or 30 degrees after seating the collar) for the two-stage TDI injectors.

Thanks!

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!

Basically, all injector calibration codes are inputted in the ECU from the factory. These codes help the ECU determine the specific output flow of each injector as no injector is exactly identical. Now, wear and tear or repairs such as replacing some injector internals with bnew ones will give a different output than the programmed data in the ECU. This scenario requires a special machine such as Hartridge Injector Calibrators to generate new calibration codes for each injector then you can input these codes in the ECU using a scantool with an Injector Coding function. If you just cleaned the internals like we did in this video and didn't notice any loss of power and high fuel consumption afterwards then you're fine. But if you did, It's best to bring your unit to a calibration shop that can test/read and generate new calibration codes for your injector.

@@btdgarage Hi, thanks for very detailed explanation!!! it is very clear now!! another question and last one is if is necessary to ANNEAL the washers under the injectors before mounting or not? Thanks again :-)

@@martintoman6266 Thanks Martin! Annealing the washers isn't necessary but also not a bad idea if done properly.

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.

Thanks!

It works for nothing, that is, it cleans the injectors but at the same time induces premature wear.

Thanks!

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

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.

@@yzmoto80 awww, the rage is cute 🥰

@@Steve_MFr LOL… 😂…Just funning around my friend, I LOVE EVERYBODY ! Without being able to joke around with one another, what do we really have to make life a little more fun ? Other than family of course !

Short answer: yes... Not all nozzles are built identical, that's why those shims exist... If you do this yourself you can experience a rough idle... But it can be done, the injection angle should be the same...

It depends on how long you were still running the engine after the HPFP was shot. Try to check the fuel rail and pipes first for debris. If you find any, it’s best to bring the injectors to a professional who can fully take it apart and run it on a bench test machine.

Hi Ray, as this video is intended for DIY only, I wouldn’t recommend a complete disassembly without proper equipment / test bench. I might make a complete rebuild vid soon though :) Thanks!

Hi! 50Ft lbs or 67nm. Thanks!

Thank you!

Hi Paul! Not really but it wouldn’t hurt to pour some diesel in the holes while it’s upside down then quickly turning it upright to let it drain. Carbon buildup usually takes place in the nozzles. In some cases though where the injectors get contaminated by water or particles from dirty diesel, the injectors will require a complete tear down/reconditioning but it’s best to let a professional do it.
