How to clean diesel injector and clogged holes

[@tonybreeze8516]

In October 2022 I removed the injectors from my Suzuki GV (with the Renault 1.9 engine) and having unscrewed a couple of the needle ends so as to clean the five holes, I was perplexed as to how to re-assemble the parts and was unaware that the tip is separate from the holder because it was so gummed up with carbon. I drove to three diesel specialists asking how to reassemble them and was told “You’ll have to part exchange them and pay £165 GBP for each.” I came home feeling very depressed and then found the answer in this video. Thanks for saving me a lot of cash.

Just thinking that a Renault engine is inside a Suzuki is depressing enough!!

I have the same 1.9 with injector full stuck, black smoke all sensor are ok after you cleaned it it worked ok ?

[@Allexandru4421]

High fuel consumption also thanks

[@petersherrouse33]

I appreciate your video. I've cleaned VW and other injectors with an home style denture ultrasonic cleaner - works great! . Water and soap is all I find it needs. A few seconds will knock the big stuff off. I usually hit them with about 30 minutes or so. LUBE THEM RIGHT AFTER REMOVAL (or they will micro rust). In reassembly I flush them liberally with clean diesel fuel or cheap spray can penetrating oil. I don't recommend using a wire on the holes as it can mess up the spray pattern . The pintle pin should float in the bore with no friction,. - Be careful not to let it fall out ! Keep every thing VERY clean and flush with diesel while assembling.

[@brentackerman3787]

Excellent video Adorian. Great visuals and clear, step-by-step explanations with nothing assumed. Thank you again.

[@tinkerpertao8383]

Finally, I found a video that clearly shows how to disassemble, clean, and assemble a fuel injector (diesel injector). For the lack of parts name knowledge I would just say there are a two part nut base (one part to connect to the fuel port: the half part which houses the device with two circular alignment tab pins and the other half is used to house the injector needle), and a needle that atomized the fuel. I would hazard a guess that when the diesel fuel is under pressure it comes out through the needle as a vapor (atomized). The needle houses the pin, meaning there is a pin inside the needle, right? So the pin inside the needle controls the fuel delivery by moving up to plug the holes and moving down to let fuel pass. Right? Excellent video. 33 foot pound to tighten the nut of this certain diesel fuel injector using a TORQUE WRENCH. Wonderful, thank you so much for your time and sharing it with us.

[@nickpritchard7130]

Great vid. Been quoted $2400 to replace 4 injectors on a 2012 Audi A3 1.6 Tdi. No one in West Oz offers a cleaning service. This is a great vid showing how to save money. Well Done.. !!

[@neilburns6118]

THAT was absolutely Brilliant!!!! My only negative feedback is that on another video it stated to make sure your working area is 'Meticulously' clean, and they stressed how important that is. Almost clean room clean for working on injectors. I have the injectors you showed so this is perfect for me. Thank you. Again, Excellent video.

[@tomsurrey2252]

I was thinking that, too BUT... great video! I never thought of cleaning them but now... I will!

[@louisamotsepe2828]

I'm going to take my Mersedes to som1 to clean the Injectors. I was scared before I'm now relieved and hope they going to be fine. This video saved me a lot of money. Tnx.

[@dougbas3980]

About to do my MF35 diesel tractor injectors and this video is perfect. I will be using the cleaning products you introduced me to. Thank you; well done.

[@zachamy4444]

I have used that product and put it in ultrasonic cleaning machine. I had great results in ten minutes .

[@Itisinthehand]

Appreciate your research. Good vid. I'll do mine. Having just paid £503.00 for two and now told I need another two. I'll service them myself. Thank you.

[@Alexander_l322]

How did you get on doing it yourself??

[@edups3307]

I love these diy videos. I dared to touch one of my common rail injectors on the electrical side because it was leaking from there. I didn't know where to put the small ball that was on top of the actuator and had to send it to the shop. They fixed it up but it's still leaking. This video gives me a lot of confidence, will definitely do this sometime.

[@sepimate564]

Thank you I cleaned now my injectors and injectors knocking noise is gone and good performance great.....man

Was you car ticking when you accelerate or what?

[@oisin1980]

Best video on KZbin for cleaning injectors

[@CalTreeEquip]

Thanks, this was very useful. You would be wise to keeps those solvents off your skin. They actually soak right through your skin and can have long range effects to you nervous system. The thinner stuff goes right through your gloves as well so I usually hold whatever I'm cleaning with long pliers. Just a tip. Thanks for making this video.

[@zeez9053]

Great tip I can imagine they could cause auto immune diseases

[@Dave5843-d9m]

Most solvents are potentially dangerous but the really effective (but really nasty) stuff eg 111 trichloroethane and carbon tetrachloride are no longer available. However biodiesel is safe and a very effective solvent. There are many recipes on www. You can make a litre in a soda bottle. Just mix, shake and leave to settle.

[@brianlittleforest631]

They're using the red can of brake cleaner - the chlorinated stuff. I doubt their concerned with their health too much.

[@PINOBRE_Lang]

I'm gonna save this video, so I can clean the fuel injector of my future YAMADA 22hp diesel engine, for my fishing boat soon. Philippines Thanks for sharing.

[@Lipjam]

Excellent Video. I enjoyed watching. Your Macro shots were impressive and you've got a engaging style. Watched till the end and then said awh when it was over :)

[@coachandreas5214]

Excellent video! I am just about to do this with my 5 common rail injectors on Volvo d5 . This made my day. Methodical and explained everything with ease. Thanks!

[@TheMaxAcceleration]

WHAT A COOL VIDEO!!! Thank you SO much for this! I took my 20-year-old Mercedes to an "Injector Specialist" 3 years ago, who cleaned all 6 injectors for 400 Euros, that's about 442 US Dollars. Now, after watching your video 3 times, I'll do it myself. Although I'm a "machinist technician" I never dealt with injectors, I always thought it's a something very-very sensible thing, After watching your video, I will do it this (like you in your video) at the weekend myself, for sure, THANK YOU SO MUCH! Over here in Hungary, we don't have that cleaner, but I bought it on Amazon for 35 US Dollars incl. shipping, it will arrive tomorrow :-) I'm sooooo excited. Thank you once again!!! That "specialist" told me a fairytale about injectors.... "there are 2 very small balls inside it when you disassemble it, you may damage it, that's at least 1200 bucks for 6 injectors, etc..." Andeson, you're great, thanks a lot for this VERY DETAILED video, I can't thank you enough!!! I always get comments on my channel, that I speak and talk too much in detail, but you're my man, the truth is always in the small little details... What's the worse thing? I have to buy new injectors. But I don't care. You just empowered me :-) Now I don't even care if it gets broken, I'll try to do the same you did. If it gets broken I'll buy a new set, but it is definitely worth a try. Really Anderson, THANK YOU!!!!!!! (TheMaxAcceleratrion)

[@alfredocomparte2702]

Hello brotherx did you ever do it? how did it go?

[@vivaldivivaldi423]

The best video and correct and explained seen so far thank you the problem with the injectors has been solved

[@bad5150dab]

AWESOME! Very informative video. If anybody knows what torch tip cleaners are I highly recommend a set of them because there is different size wires in there and it is the perfect carbator tool. Not only will clean carbs but any thing mechanical that has small holes that's got to be cleaned. Can buy from any wielding supply store. 😁

[@Dave5843-d9m]

You can pick up carburettor jet cleaning kits for very little cost on eBay. But you must use a solvent because any seeds of carbon will move back down and clog the spray tip all over again.

[@jasonga]

Yay a good video, I’ve taken them totally apart before and they been fine, doing my PD injectors soon….. my local shop want £125 each to do them!! You can even buy new tips on line for them!!

[@jasonga]

I done similar to you but I also put them into ultrasonic cleaner, I couldn’t believe the dirt that came off!!

[@oisin1980]

Wow. My volvo penta 2001t just wont start. I've tried everything. Flushing fuel system' filters everything. Im confirmed enough to try this now. What's the worst than can happen at this stage. Thank you so so much

Well the are very helpful! I owning the 2006 dogde sprinter 3500. I only put a little over 1550 miles, this van are my life. Unfortunately first 3 three years it treated me like king but I wasn't take good care of it. These 2 years U very struggle and very frustrated with the van . No how to get it back normal performance. Well before I took all 5 fuel injectors out and clean them but not same as your's the video your shares. Now it doesn't at all . Please do you any solution that I can get on the road?

[@Mancavedweller1]

Awesome tutorial. Thanks you very much.

[@dredrotten]

The proper way to do it is to drop the injectors into an Ultrasonic bath of diesel and detergent for an hour or two (overnight for the really bad ones), give them a rinse and you should be ready to go.

[@propatria4258]

do i need to disassemble injector when dropping it in bath?

[@reinhardtrippmacher8776]

I was waiting for that comment. In general yes it is the way to open them but a steel wire in the holes and a steel wire brush are a big no no.... Yes and you have to dismantle them when cleaning with a ultra sonic cleaner. As well use nitrile gloves and a lubricant when touching them. Sweaty fingers can course corrosion!

[@carlluscombe4011]

Good video thanks for taking time to make

[@gregcy89]

Thats amazing! I wonder if its the same for all diesel injectors...

Interesting video I will give this go on my old injectors then see if tmit works thanks…I don’t have a newton tought wrench guess I could guess it…

[@chrissygizmo6057]

Thanks for the tip on how to separate the injector, I didn't have a Scooby, but im an expert at prodding things into holes to open them up , hence the reason I've got 4 kids to 3 women lol

THANK YOU, VERY CLEAR, LEARNED A LOT FROM YOU, GOD BLESS!

[@ernestoramon3700]

Best way to clean injectors, fuel pump, pistons is putting ATF transmission oil in the diesel tank once a month for example I put two gallons of oil into 200 gallons of diesel restores power eliminate black smoke.

[@rockyfish3115]

Just run some two stroke oil through it this can clean the tips and help lube a sticky injector

[@VeryMuchBlessed]

Very good info. Clear and concise. Thanks much.

[@richardtaylor6322]

Excellent video thanks

[@bicanoo_magic3452]

Trust a Mexican to give an Ozzie the best advice of a lifetime!! I have a stupid diesel with two non-functioning injectors.. They HAVE to be blocked but no ''mechanic'' can figure out the fault. I KNOW we have shit Diesel quality in Australia so this HAS to be the cause.. the injectors are AUD$550 ea.. so I will DEFINITELY be doing this to each and every one..! Thank You so much!! BTW> We definitely have CRC Brake cleaner.. but the other stuff is a quandary.. what's the base ingredient? (If it says to on the can!)

[@bicanoo_magic3452]

So guess what? We resurrected the injectors and they were ALL saveable.. two of them blocked (friggin hard to see) but unblocked the tiny hoes , blew back with air by electronically opening the injector.. you should have seen the shit that came out.. we have now installed a secondary filer and gromerlator.

[@dopiaza2006]

Great video. Just for info, you shouldn't continue past the first click on the torque wrench.

[@salty987]

I did a leak test and it leaks, if i clean it as you show can it be good again or do i need to recalibrate the injector after at a diesel shop?

[@gaminginmy60s]

Very well done video.

[@RC-Heli835]

Cool! I like fixing things if at all possible, if they have any life left in them. Right now Im fixing a siezed up air compressor off a wheel barrow compressor. The thing had sat for years tucked away in the shop and wasn't used because a hole had rusted into the bottom of one of the tanks. I fixed the hole with acetylene welding and cleaned out the fuel system to get the engine running again. The twin cylinder compressor ran very strong and would do 160 psi with ease so I liked having it on my work trailer. It would actually run a 1 inch tire gun just enough to take a truck tire off. The compressor was low on oil apparently which Id never thought to check and one day while running it on a 16 degree Farenheit day for just a few minutes before the compressor sadly locked up and came to a screeching halt. It has set for 3 years now taken apart and I got the idea that I would file the gaulding off the crank and recondition the rods with a brake hone. And what do you know? I have it back together now with smooth working rods and crank. I liked the compressor especially because I got it off the shelf and gave it life again. I gave it back its purpose. I made a place for it on my trailer. And I'm fixing to do it again.😎🙂

[@shadowwolfXD97]

I know its 5 months later but why the hell would you do all that and nit change the oil.......

[@Mercy1976]

awesome video mate

[@nicovanzyl3631]

Enjoyed the video. very good advice

[@den.staar124]

Are those electrical (Delphi I )? - I'm afraid to throw money, I'm going to plug them in when they're out, 1 is bad, 2 I don't know. And put them back to their cylinders (teach-in). Iron filings from the vane pump could also be used, no additives will clean that. So they have to split up to clean. Thanks for your video.

[@paul-xl6hk]

Thank's i fixed mine today 🖐️😀👌

[@josepeixoto3384]

i would try to use a copper wire strand instead; the steel you used is a hard steel bristle,and it may have messed up one hole,we can see it spraying differently than the other four; but then again, in this case copper probably would not have done it...

[@stefanraileanu7744]

What is the solution on the bigger mate?

[@danbrown935]

Hi. I have a 2005 bew 1.9 tdi. Will the tips of injectors come off the same way? Will they clean the same way?

[@kevinhancock4064]

Why did one hole seem to be spraying more than the others ?

[@zsigerr]

Hi! After this disassembling/ cleaning /rebuilding, does the car or the injector need any coding? Or just put back in the car and it will work fine? Thanks!

[@stanciubogdan6432]

Hi. No code needed. These are mechanical governed injectors,not electronical.

[@johnswimcat]

Could you sleeve a piece of plastic tube over the tip body, then blow dirt out backwards with compressed air?

[@brianlittleforest631]

Yep. Better to blow any debris back out the way it came in.

[@TMar06]

Great video!! I have a 2008 Sprinter van and luckily the nozzles (all 8 ports) atomized with no blockage. I do have another question. There is a washer/spacer inside the barrel if I pull off the piece u said don't take off (mine fell and it came off) along with another cylinder piece. Do you know which side of the washer goes in first?

[@AndersonERockefeller]

TMar06 Well... when I took an injector apart the first time all and all the parts fell out and I'm like...now what??? so what I did is took a second injector apart slowly piece by piece this way I can put the first injector the same like the one that I took apart. just don't mix the parts from one injector to another cause it will be off calibrated.

[@TMar06]

Anderson E Rockefeller Thanks for the advice! :-) I was hoping to get by without pulling another injector. 😂😂😂

[@1112223333111]

when you poke out the obstructions, spray the cleaner backward into the tip a few times and smack the bottom down on a piece of wood, clean wood with a clean towel on it. Then test the pattern. I'm going to be doing my injectors soon on the 7.3 and every video says nothing about the tip, its critical. Good job

[@runeviking5770]

By spraying it opposite of the fuel flow, it's easier for build up to come out.

[@masterfoodrecipes3963]

This is a nice video. Does clogged injectors cause P0093 code?

[@robl1967]

Can you use wd40 to clean them?
