How To Clean Fuel Injectors

[@BoringJohnson]

Good guide. But remember that if you got a newer car you need to place the injectors where you removed them or reprogram the cars computer.

[@randym.hernandez1408]

Yes be careful not to mix them up.

[@Rythecarguy]

Wild, Didn’t even know that was a thing. Great tip! I will pin this comment.

[@kellismith4329]

Yes good idea to number them, I am ocd about that everything is numbered, firing order and distributor map/rotation etc drawn under the hood for quick reference - some bolt torques too

[@raiderman28]

Excellent video

[@418lightning8]

I dont believe that because what happens when you need to replace one do they make a specific spare now you can't change with different types only because they have different connections please tell me which vehicle needs reprogramming for new or moved around injectors

[@jasenkeblbek2740]

Bro thanks for the video. Had a bad feeling about this shop talking about replacing basically my whole fuel system as they knew I didn’t know much about cars. But saw your method and thought wouldn’t hurt trying it out before spending the 800 bucks they quoted me. Needless to say my car is running and feeling like it’s new again. I had an engine light on after doing this cleaning code is gone hasn’t came back and you literally saved me 800 dollars. Thanks much my guy

[@Rythecarguy]

That's so awesome to hear and it's stuff like this that makes me love making these videos. Thanks for sharing!

[@RoxusRemo]

What symptoms did you have before you tried it?

[@alfonsoramirez6415]

Love hearing things like this i thankful for people that make videos and share knowledge

[@gear_up_guy]

Also good to try and spray the cleaner before pulsing to check if you have a leaking injector, nothing should spray or drip without power being added. Thanks for the video.

[@Smoked786]

I remember cleaning mechanical injectors on my old Mercedes. Always did it with diesel, or at least the final rinse. Good cleaning agent, lubrication and no fire hazard while testing spray patterns.

[@wynnpham631]

Thanks for providing the principle of fuel injector cleaning, in the past I replaced all for new ones

[@Rythecarguy]

No problem 👍

[@naturoidz2714]

I remember I did this, and the pressure made the Injector flew out of the tube and Carb Cleaner sprayed right in my right eye 😂😂😂 I stumbled my way to the faucet. And my eye was red and slightly blurred for the next few days 😂😂😂

Well explained, has going to be doing mine, been looking through various sites, clarity 10 out of 10,

[@MarioHeadJr]

Want to try this on my 2000 GMC Sierra. It’s got over 300k on the dash with original injectors

[@mclehed77]

Wow 300k that's amazing I love it 😁👍🏾

[@Rythecarguy]

You should! I might help out power if they are a little clogged over time.

[@kellismith4329]

Don’t those trucks have the injector spider setup that lives inside the intake ? I don’t think you will clean those ones up so simply it involves removing the upper intake, annoying fuel line connection nuts are buried behind the firewall. Those ones I wouldn’t try to clean just buy a new spider and a seal kit as they are upgraded design kits.

[@igotstoknow2]

Missed a step: Reverse clean to force dirt out of the injector filter (fuel rail side).

[@Rythecarguy]

Oh yeah

[@juniorcruz960]

This will help me save on buying new fuel injectors for my 89 miata mx5 new ones are spendy an the fuel. Injector tester or cleaner on Amazon is cheap 25 something not bad man thank u on the heads up on finding a tester or cleaner tool. Gonna buy me one to clean out my injectors and gonna buy new rubber rings for the injectors as well this will help an save me money n time from buying new ones thanks again man glad I KZbind this.

Thanks car dude! Excellent! Thanks for sharing our knowledge

[@williamkummer4728]

Hey Ry, is it necessary to clean the fuel injectors as well if running a pressurized cleaner through the manifold?

[@olenaerhardt7725]

If you remove a new o-ring before cleaning (for some reason even a new o-ring gets slightly torn during cleaning by that white plastic connector, which sprays, so I use a separate o-ring for cleaning, then remove it and put back the original new one) can you put it back? Or once removed the o-ring should be replaced even if it is new? Thank you for a great film.

[@CycloneCyd]

Your question seems a little self contradictory, but I would use the old o-ring for cleaning the same as CG did and then replace it with the new one.

[@olenaerhardt7725]

@@CycloneCyd Yes, I'm sorry, just thought about 2 procedures and described one. See besides that cleaning I also replaced the o-rings on the bottom of course, but they were wrong ones (too thick, I couldn't install w/them into the Intake Manifold. So I removed them and put thinner ones fm/another set. I'll use those removed for cleaning, and asked out of curiosity, could I possibly reuse them. Also could be you installed the o-rings and then decided to clean them, so you remove those new o-rings, clean the injectors and put back those removed. Also there are methods to clean without o-rings, but rather using a clamp. Thank you for the replay.

[@kellismith4329]

@@olenaerhardt7725 yes you can reinstall newer ones again as long as they aren’t damaged

[@greasemonkey5340]

Do the injectors for the Xterra and Pathfinders 4.0l 6cyl have a filter?

[@butchgreene]

I'm getting a P0303 on my 2005 Xterra at 217k miles and reading in thenewx forums, more than one guy has indicated a failed injector on cylinder 3. If it is, is there a test I can do to know it's the injector after I try swapping #2 & #3 coil packs to test for that simple fix? And is there a way to run any sort of cleaner into my injectors that might clean them out and avoid me having to dig into them?

[@CycloneCyd]

Those look suspiciously like Denso injectors. Don't they have a microfilter at the top? Nor any plastic o-ring retainers?

[@Rythecarguy]

No I didn't see either

[@ahmadghosheh3104]

Good video Ray. On the injectors, if the spray tip screen is covered with varnish, brown or even black, should it be cleaned or get new ones? They work fine and spray good, but look like crap.

[@Rythecarguy]

Did you try soaking a q-tip in cleaner and rubbing the tip? That should clean it up. If that doesn't work you could probably soak them in a shallow tray. Afterward be sure to run cleaner through it to get anything that may have gotten in there out.

[@CycloneCyd]

@@Rythecarguy don't soak injectors in a tray where they lay down. Find something the injectors can 'stand' in (like an aerosol lid or old mug), place the injectors pintle down and put in enough cleaner to cover the pintles only. If you soak injectors laying down so the cleaner gets inside, it can damage them (in particular dissolve the coating on the copper wire of the coil causing a short).

[@TheMrBennito]

@@CycloneCyd thanks, yet what is a pintle? Sorry, I m Dutch, don't know the word

[@CycloneCyd]

How do you remove the fuel line from the fuel rail on a 2014 Xterra. None of my disconnect tools will get it off. I've tried 5/16 and 3/8. None of my disconnects are metric.

[@pisanu6699]

When carrying out cleaning, it is essential to plug the various pipes in the circuit (of fuel injector) I don’t know what these pipes are and what they are used for. Can anyone help explain this. Thank you so much.

[@olenaerhardt7725]

Can you apply 3M Silicon Paste (Dielectric Grease) on o-rings instead of car oil or always oil?

[@CycloneCyd]

Yes, that's what I showed in my video on injector rebuild. Just a smear mind.

[@yoonkim4838]

Quick question. Would it be a good idea to replace the dampener since you have the rail out already?

You can if you want to knock it out for maintenance sake but it's usually a simple diaphragm that lasts as long as the car.

[@skytech_00]

Is it true for 2006 infiniti vehicle that injectors are specific to their spot on the rail?

[@pauloisidoro2]

I saw a guy putting some automatic transmission fluid inside the injectors after cleaning them 😳 i just wonder why?

[@eugeneanderson7984]

ATF is the age old trick to add into fuel to lubricate your injectors it has emulsions that stick to the Stem and barrel keeping them fresh.

[@tracy062]

is there a difference in the fuel consumption?

[@Rythecarguy]

I'm sorry but I never checked any of that.

[@Dnasty1]

If I recently changed my O rings like a few months ago can I reuse them or do these become bad as soon as you pull them out?

[@Rythecarguy]

Eh. I would send it, you should be fine. Just check for leaks when you first start it back up

[@Micscience]

That is such a cool little fuel injector tester. The issue I have is the spray can I have does not hold pressure. It leaks where the straw and the push nozzle join so I have to buy a different can.

[@kellismith4329]

You can put some heat shrink tubing between them and heat to form a seal

[@bobbofly]

Speaking as one who's maced the crap out of himself MULTIPLE times (you'd think I'd learn, but nope) over the years/decades with brake/injector/carb cleaners, I heartily applaud your call for eye protection. Man, that 💩stings. I've actually become something of a connoisseur. They should seriously tout the stuff as bear repellent.🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣

[@elgastsos210]

What would cause the injector to stay slightly open after the car is off, leaking into the cylinder, causing a sluggish/rich start if tried to restart after sitting 10 mins. The gaa will evaporate over night and starts fine. Do you feel the injector is fixable/cleanable?

[@georgespangler1517]

There's a spring loaded seating valve in injector and an above solenoid that lifts it off the seat per pulse, spring can go bad are like a engine valve the seat can wear and cause the leak down,, replace the injector but keep an eye on engine oil for gas smell in dip stick,, a leaking injector can destroy an engine
