- Upper engine and injector cleaning on a 2006 Chevy Silverado 2500HD Duramax LBZ motor. I ended up breaking the bleed screw but had my old one as a spare. Thank God!! At one point I didn't realize I was recording the wrong way. Sorry about that. Overall an easy job and a good maintenance for injectors that are getting high mileage (mine have 194K miles).

This is by far the best video I’m seen on this procedure, that you sir.
good info !!!!!!!! the very FIRST time my screwdriver slipped i saw the writting
on the wall and bought a long handle BUT DRIVER JUST for THAT screw !! lol 8)
TOP NOTCH VID
Thanks and thanks again for your comment section is pure truth very awesome
Thanks for this. Great tutorial.
I've read all your post and no one mentioned if you replace the fuel filter. One video said replace the filer before you begin your procedure. I would seem to think you would replace your fuel filter after it's all done. Any comments would be appreciated. 2004 LLY one owner "me". 206000 miles.
I didn't replace fuel filter and didn't have any issue. I suppose it wouldn't be a bad idea, especially considering they aren't terribly expensive.
BMW has the original injector cleaner for diesels at a fraction of the price. I believe I paid $35 and it’s the original stuff. Not the acdelco stuff. Way better and way cheaper.
can you post a link to this stuff, or a part#. I've heard about people mistakenly running something designed for gasoline engines..
This product is no longer available! Is there another similar product to use?
I did this to my Lb7 2 weeks ago and it smokes twice as much. Also my lisle disconnect tool would not work for my 1/2 inch supply line so after quite a bit of struggling I connected the 1/2 inch supply line right to the fuel filter and had no problems. If you have problems with the fuel line disconnects then just use the lines on the filter.
As you have no doubt come to realize, inferior VCO injectors on our LB7’s are prone to not shutting off properly, causing leakage and coking of the nozzle tips 😟. Look into SAC’s which are available in OEM delivery rates. That type was used with much better reliability on all Duramax after LB7.
Boke off the drin screw on Colorado ZR2 no replacement from GM. Have to replace entire dual filter housing.
Damn that sucks!
This cleaner is discontinued. Do you know the new part number?
The BMW diesel injector cleaner is reported to be a very close replacement. Amazon link: CLEANER www.amazon.com/dp/B00TMV4A2W/ref=cm_sw_r_cp_api_glt_fabc_J1MDHS2VYDVHV2D434SH
How did balance rates go?
Could just use marvel mystery oil in your fuel
Hey I’m totally confused . I went to a Chevy dealer to get this product and do it on my 01 Chevy Silverado duramax and was told that acdelco is for gas engines not made for diesel
This product is a fuel injector cleaner. If you buy the bottle in the video....it should do the trick. DO NOT add it to the tank. It must be mixed in a container like I did and run from the fuel lines in the engine bay. Both gas and diesel use fuel injectors and this product do not state gas vs. Diesel injectors.
Check around on some diesel forums if need be for peace of mind.
Paul the Wxguru completely understand but I can’t find bottle at any local parts stores out here only gm dealers carry it but won’t sell it cause it states in there system that acdelco bottle is for gas engine only due to that reason they won’t sell it to me ...
@@leonmatos5367 I would check around Ebay, amazon, other places.
Apparently they discontinued this product and went to a different product....likely to try and capitalize on the diesel market. Bet they create a product soon targeted at diesel applications.
But they most likely had your injectors and filter and a mechanic ready to take your money why would you go to a dealer stealer just punch the numbers on ebay and the name of the product
Thanks for posting !! Does this also help with the gases being regenerated by the egr valve?
That I am not sure of
No.
How did u get it to crank? I’ve primed like a quart out of the jug and won’t crank
Question! You gotta Have the Fuel lines empty To do that or nah?
Did the cleaning take care of the high end sluggishness, mine had been doing the same thing
Absolutely it did. It also smoothed out the idle.
why are you priming the system with the lines disconnected. You have disconnected the complete system when you disconnected the fuel lines to hook your two hoses up that go in to your jug. You prime the system maybe after you reconnect your supply line.
When disconnecting the fuel lines like this, the lines that are connected and in the jug are full of air. Priming the lines draw fuel from the jug thru the lines and into the filter. Had I not primed it, it would have died due to drawing air.
The filter is drawing off the jug at that point for the duration. Same concept still applies.
Next time if you break the bleeder screw all you need is a small flat head and you can back the screw out. I've done it twice that way you made that way to hard on yourself...
Thanks for that tip!
Paul the Wxguru Did this change/improve your balance rates for the injectors? Did you test them?
Bryan, I cant honestly say. All injectors a few months prior were within specs. I did notice however after the clean out, the idle was smoother. I did not check the balance rates after as I didnt have my buddies checker.
How much injector cleaner do you add to that gallon
The entire bottle
Dumb question, if the fuel filter housing is deleted. What should you do to prime?
Jacob, I would just turn the key to the run position. It should activate the fuel pump....I think
Is there a fuse for your tank to unplug ? Obviously I unplug my airdog.
MTroughneck83 nope. I didn't anyway. Wasn't a need
My sending fuel line spraying diesel all over when I go to start my 2003 Duramax. Any ideas??
Spraying where it connects to the rail or have you got a fuel line spraying at the fuel filter housing?
If it is spraying at connection to the rail, it isn't clipped on properly or the crimped fitting is damaged.
Do you have a lift pump? 🤪
Doesn’t letting the truck idle that long wash the pistons with oil.? Does the benefit of the injected clean outweigh the damage? I’m a Deisel newbie thought I’d ask
Na most of the ac delco shit I beleive I’d diesel with extreme additives, it burns like idling diesel
Also what are signs of leaking injectors because my truck is kind of sluggish and maybe surging I think don’t know and I’ve also been using more diesel than regular and I’m thinking it could be a leaking injector(s)
If you have an injector leaking....or hung open, it would be dumping more diesel into the combustion chamber and I believe you would get excessive black smoke.
So did this fix your injector problem?
Gary Campbell I had a blown head gasket at one point. This was just a cleaning to try and take care of the injectors since they were up around 200,000 miles.
@@paulthewxguru5899
So how much did it cost to fix the head gasket? I have an 05. Not sure if it has a blown head gasket or not but I see a puff of white smoke once in a while.
@@ozziecrosby2092 I had them preface both at same time and use Grade C gaskets. I also had all of the rubber hoses replaced while they had top torn off, clean injectors and clean egr. Total with everything was $3,700...and that was a labor rate of $75 which is a bit below average for hourly rate. I was fortunate to have a great diesel mechanic close who didnt gouge
@@paulthewxguru5899 delete egr.they kill engines
Can i take out my injector an re-use it back in the same cylinder
Yep you can....I would clean it while you have it out.
If you get a new injector it would need to be programmed into the ECM before installation I believe so everything works right.
But since it is same injector just pop it back in.
You don’t have to program new injectors necessarily
Do you use the whole bottle of injector cleaner?
Sorry just seeing this, yes the entire bottle gets used
Can you use diesel kleen using the same method? Just wondering as I would think it would have better results using this method instead of putting diesel Kleen in the fuel tank on account I can't get my hands on any of the ACDelco stuff also cheaper
No, different product altogether. The AC Delco stuff is a concentrated bottle of cleaner. You can buy on Amazon. I ran Diesel Kleen at times, however I preferred something a little more powerful and lubricating. Stanadyne Lubricity was one a few others.
I have an 07 LBZ thinking my injectors could be bad or dirty because the acceleration is very poor and when I drive it when I press on the pedal a little not it’ll start making a weird sound kind of like its klacking and it has a bad tick noise at idle and also do bigger tires affect these trucks as far as speed and acceleration do you know? And also what kind of injector cleaner is that and where did you get it?
The clacking sounds like an injector hung open. Any smoke with it?
It you get a constant tick at idle, it very well could be a blown head gasket. Check your coolant hose after it has completely cooled. If it is still pressurized, you likely have an issue.
The good news is, the 2007 as far as I know all came with the riveted head gaskets. My 06 LBZ still had the crimped design, but it changed mid build on the 2006 to the riveted designs.
Paul the Wxguru yes I have a tick at idle I’m hoping it’s just dirty injectors getting some injector cleaner tomorrow I hope that will fix the problem if it’s a head gasket I don’t know what to do I don’t know how much they are but anyway sometimes when I drive my truck some days it’ll run smoother than other days it’s weird like it’ll run good one day and the best day it will run rough I don’t know hope it’s not a head gasket or I better have a deep pocket
@@gamerbeastboy1842 that sounds like injectors are worn out. How many miles on truck? On the LBZ a shop will charge about $2600-3000 for injectors and install as a package.
I had head gaskets done and had them replace all of the rubber hoses while they were working on it....and clean the EGR. Total was about $3900.
Paul the Wxguru I’m probably just gonna get an EGR delete kit and thanks for all the help I’ve really been wondering what was wrong and I checked the coolant hose and pressed on it it’s all good so I don’t have bad head gaskets or anything sounds good man again, thank you for all the help oh and the truck almost has 198,000 miles on it
@@gamerbeastboy1842 with 198000 your injectors probably are getting a bit worn out. Regardless of the EGR delete kit....get the cleaner and run like the video here. Then get a bottle of the Stanadyne blue or gold label (most expensive)....and dump the entire bottle in a tank of fuel. That is not typical....but it will help also.
After that, run the Stanadyne Lubricity formula (purple label) with each fill up.
Been asking all around TH-cam and got no response. Do I need actual diesel fuel lines to do this or just fuel lines?
J. James Sr. Diesel fuel rated lines. That is what these are
Using rubber lines temporarily would be ok as long as they are heavy enough and rated for auto use, my 1/2 inch line was rated for fuel and my 3/8 was a coolant hose.
How's the truck running?
It was running well when I sold it. Had 212,000 on it and going strong
How often can you do this cleaning?
AirborneTejano Some people do this every oil change. Now that I hit 200K last month, I probably will do mine every 7500 miles. That gets expensive but injectors cost alot more in the long run!!
How much do you use for each cleaning?
AirborneTejano the full bottle. You mix with atleast a half gallon of diesel
would this still work if i have a fuel filter delete
brian k I believe so because you are hooking these lines straight to the fuel rail where you have pulled the primary fuel lines. I would just make sure whatever container you do this from is 100% clean and dry. I used a purified water container that was empty, and dry. No grit or anything in it. Wouldn't want to chance sucking something like dirt grains or sand into an injector...that would suck the big one.
So you didn’t have to do anything with the fuel lines? To block off while doing this? I wanna do my 06 soon
Nope. Once disconnected from the rail, there is no suction or anything on the lines to draw fuel. I also do not have a lift pump mounted anywhere between the tank and the fuel rail either.
@@paulthewxguru5899 ok. Yea I found some of the cleaner but not paying what they want for it.
So I did this and well 1 injector was trying to stick and now I have 3 junk injectors lol any reason why this is has happened . Non douche comments appreciated thanks !
Can you use clear lines does it have to be fuel lines
Need to be using fuel grade lines yes. I would not use clear.
Warning Bleed Screw: I've read and seen the bleed screw heads break easily in cold.
