HOW TO CLEAN DELPHI INJECTORS LIKE A PRO | 2022 ULTRASONIC CLEANING DIY | NOZZLES | DISASSEMBLY

**MUST READ**
Hi guys here's a DIY guide on how to completely disassemble & clean your Delphi injectors 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 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.

Many thanks from Brazil bro!!! After being played the fool in +- $400 I got sick and decided to give it a shot...the car doesn't "smoke" anymore and I feel so good about it. I haven't got the ultrasonic cleaner but let them immersed in wd40 for the night and they are awesome now...cheers !!!

Awesome! :D

Top video thx 👌 going to do my injectors 1 by 1

[@robertgrzywacz3236]

Hi great tutorial, could you tell what fluid you use for ultrasonic cleaner

[@marke293]

Great video but can you tell me where the spray holes are as I have a set of these to service but cant see where the spray holes are ? Thanks

[@joseraulmatosperez6533]

Hola,muy bueno el vídeo quiero hacerlo a mis inyectores,donde comprarse la máquina de ultrasonidos y cuánto cuesta gracias 😅

[@mastercode2188]

Please make one video with piezo-electric injectors

[@redmorphius]

Can you show before and after pop testing?

[@josepeixoto3384]

How do you take out the solenoid? Just force it out at the gold-plated contacts? I wonder why the Factory forbids the use of ultrasonic cleaners, i was readingthat in the manual.

[@winstonbrown1516]

Hey mate, what liquid did you use in the bath?

[@danieljeune1952]

How did the screw driver push out the solenoid valve cause the top of the injector is sealed

[@zekidedecan600]

Hello, I put a new Delphi nozzle and return valve kit on my injectors. I assembled it exactly like in your video. My car started after a few attempts, the car is running well, accelerating normally and getting good fuel consumption. But I hear a noise around 2,000 rpm like a frufrufru... I didn't do the diesel return test to see if any injectors are failing. Do you know what the problem could be? Thanks And happy new year!

[@btdgarage]

Hi! Some noise is normal for the first few kilometers due to air that got in the system. However, if you’re way past 100km and there’s still some injector noise, try retightening the injector clamps to spec and make sure the injectors are seated properly

[@JeanMelim]

The first time I assembled these injectors, I assembled them with a kit from Aliexpress. Lasted 30 thousand km. this time I used the original Delphi kits. I did all the tightening with the torque wrench at 60nm. Yes, for the first 30/40 km there was a loud crack, crack, crack, and then they went silent. I'm just going to do the return test to see if they're all balanced and then I'll try to re-tighten them. Then I come here to tell you what I discovered. Thanks

Limpie los 4 inyectores de una hilux toyota diesel 3.0 srv, arranca bien, ralenti bien,pero en la ruta las revoluciones suben muy despacio hasta tomar velocidad.debo calibrar inyectores con la ecu?osea codificar? Son los mismos inyectores q estaban colocados.

[@AreskCSGO]

Tienen que calibrar los inyectores para que tengan buen flow

[@stanislavstankovic1484]

Hallo, please your answer - what minimum power of ultrasound in Watts and power of heating in Watts must an ultrasonic cleaner have to reliably clean the injection valves, nozzles ? What was your cleaning solution and what temperature you set for cleaning ? Thank you for your answer in advance.

Many times i can not do bubble off from injector and then car is not starting is there a tip for putting air out from injector?

[@btdgarage]

Hi I’ll try to film the process on another video :)

[@earthlingak]

Excellent video. I followed it to the letter. Put it all back together (Alfa 159 JTDM ) and it won't start. No fuel going to the rail. Any idea how to prime system? Thanks for vid!

[@btdgarage]

Hi! These delphi injectors require a fuel rail pressure reading of around 4200psi and up when cranking before the ECU will energize the injectors to start. Best to bleed the fuel lines first with the injector plugs disconnected until you get a decent amount of cranking rail pressure (use a scanner with live data stream) before cranking it with the injector plugs connected. Also, starting these injectors without bleeding them thoroughly often results in air lock

[@demonautomotive2726]

Just suck on the return line for a minute with a vacuum pump, you can find points on the high pressure fuel pump or on the filter (and block off the other hole if you hear air being sucked in again). I have been using one from Sealey that works on my air compresser for +10 years. Still sucks like a champion. :)

[@demonautomotive2726]

And on some cars you'll need to turn the ignition on so it's best to do that as wel. But listen carefully, because some also have electrical fuel pumps in the tank, that you don't get sprayed when taking of a fuel hose. If you have one like that just cycle the iginition on/off for 10-20 times. Some can be a real pain in the ass to get started, been there done that. But a good suck on the return line always does the trick.

[@MrLeslloyd]

@@demonautomotive2726 Is air allowed to flow out the return line?if injector is ok?because we are getting air in our fuel filter canister,and return line T's into main fuel supply.No air coming from fuel tank.

[@Crypt0Normie]

Is there anything to refurbish on the electric side of these

[@joshsica2520]

How do you remove the large pin on the second part of the disassemble , I notice you you used some king of force to assemble it , can you explain how to remove it ?

[@btdgarage]

Hi Josh, you have to push the other end up (where the connector goes) with a flat head screw driver but be careful not to bend the pins. There’s two pins on that end but pushing just the longer one straight up is enough. Just keep the screw driver horizontally flat. It’ll have some resistance since the solenoid end has a rubber O-ring on it but It’ll go with a few push. Check 1:29 (bottom end)

[@joshsica2520]

@@btdgarage great thank’s Got it

[@danieljeune1952]

Do you stick the flat head inside of the inlet side of the injector

[@danieljeune1952]

Ohh ok my bad I just noticed your talking about the electric connecter side

What's the liquid you use in your ultrasonic cleaner?

I would think it distiled water thts why he said put into diesel straight afyer to stop flash rusting 👍

60 Nm tork is very hard. ıt is false information.ıt must be only 30Nm

[@btdgarage]

Whoa, clearly you don’t know what you’re talking about. Better stay away from injectors bud. And it’s TORQUE btw

[@voicu780]

50Nm tork . When the valve return, it’s new. When it old 60Nm

[@polystone806]

Dont do it at home.the injector after being opened it must have a new calibration on the test bench. This is a nice video to show but so wrong.

[@damirivancic4964]

you can calibrate with diagnostics delphi? do you?

[@polystone806]

The calibration must be mechanical not by software. Delphi injector coil dont have to be removed.the sensitive part in this injector is ils valve.

[@damirivancic4964]

how to do it?

[@polystone806]

@@damirivancic4964 simply you change the Old valve With a new one and the calibration must be on the test bench.
