Could you possibly list a part number for the module? I’m pretty sure I’ve found what to buy but I want to be 100% before I pull the trigger.
You should get the part number from the old module for best results. Otherwise, your local dealership should be able to look it up for you by Vin number. Thanks.
I accidentally put 2.5 gallons of DEF in my fuel system For my brand new 2023 f350 and drove about a mile and my truck started to sputter. I immediately pulled over to a nearby Wawa gas station and got my fuel tank drained because I knew I had def in the fuel system. I got it drained on the spot and ran a few gallons of diesel to flush even more out and than I completed filled the tank to dilute whatever def was still in the system and I put a super concentrated bottle of fuel treatment in the fuel tank. The truck was able to run without the sputter but I had a huge loss of engine performance because the system detected water in my system and recommended me to drain my fuel filter. I drained it and all of my power was restored. I even drained the filter a second time for good measures. I drove around until I got down to a half a tank of fuel and I fueled up again to the max a couple days ago. It’s been 3 weeks since the incident and the truck is still fine. I called around and was looking at online post. All i been getting was “that truck will never start again” and “you screwed up your truck. It’s over”. A lot of you guys tend to exaggerate. I’m not replacing my fuel tank and lines and pump. If you catch the problem early enough you will be fine.
Thanks for sharing. Usually the problem shows up later as the pump and injectors will usually get damaged from the DEF and then it slowly gets worse.
@@DadsGarageDiagnosticSpecialist how When I literally drained the system immediately after my engine sputtered? Then I ran a few gallons of diesel to flush it out even more, drained it again and filled up my system with fresh diesel, AND drained my fuel filters twice and I have a concentrated bottle of fuel treatment/injector cleaner that’s good for 300 gallons inside the system. I even filled it up again with fresh diesel after it was on half tank. The def fluid is way too diluted to cause any damage at this point. All of that stuff is going to get dumped into the filter. That’s what the filter is there for. It’s been drained of a lot of that def. I drained it until the pasty white stuff no longer appears. Some of these shops just want to take as much money as they can from out of people.
thanks for the video , does this work for long mileage cars , mine 260k KM second hand never been flushed and i got TCC shuddering (60-80 KM speed ) , other functions working properly
Yes changing the fluid helps a lot on high mileage vehicles that haven’t been serviced. Thanks.
My cousins 2108 Impreza goes dead overnight if she leaves the key in the ignition. Dont know what is doing it, but the simple workaround was to always remove the key.
Thanks for sharing.
We're looking at the battery neg still connected. And you're removing the fuse box.
And nothing bad happened. Thanks.
Hi how do you flash the system?
You need the equipment and subscriptions. It’s easier and cheaper for the average person to take it to the shop to have it programmed. Thanks.
ive been dealing with this code for too damn long, i already spent 6k on a transmission shop and they couldnt fix it and told me not to bring it back......no honor or backing in their work. so given how this cruze looks identical to my 2014 impala lt 3.6 flex fuel, im going to take apart the fuse box and see, test for continuity from the box to the connector also. it has a new TCM in it, not even 2 weeks old. the way my car is right now, i cant use it for work because it wont past inspection.
Sorry to hear that. Sounds like it needs a diagnosis. Thanks.
is that being blown by an exhaust leak or boiling off?
The exhaust was still cold. It’s blowing bubbles in the soapy water. Thanks.
Where r u located? I need someone in sacramento california that does your job with the similar knowledge
I’m not accepting work from KZread at this time. Technicians in California are some of the best in the world, I’m sure you can find somebody close to you. Thanks.
So good! Just subscribed 👍🏽 Appreciate you sharing your problem solving process instead of just here’s how you fix it
Where did you find the specs and schematics?
Thanks! We get them from ProDemand or Identifix.
Great info, thank you for posting!
Thanks!
He could have started it up 😅
Thanks for commenting.
Yes my uncle had one he was a left handed machanic wish I knew what happened to it. My grandpa would pick it up to use it and get mad and throw it down.
My dad gave me this one and he still has a couple more somewhere. People think I’m kidding them when I show them. Thanks.
What is that he using to put on the glasses
Heat shrink tubing from the hardware store. Thanks.
Were do you get piece from , and what's it called
Heat shrink tubing from the hardware store. Thanks.
Thank's so much ❤❤❤❤❤

Same fucking problem on my shitvolet Fuck this car. Garbage designer (GM)Garbage motor-vehicle
just replaced the ect sensor and thermostat on my 2018 3.6 canyon and my truck still will not get up to operating temp any ideas?
Did you use OEM parts? What temperature does your gauge display? Your temperature gauge should read approx. 190F-210F at normal operating temperature and should stay there while driving. Thanks.
Yeah sounds like my 6.2L at 65k on it
Sorry the hear that. Sounds like you need new lifters. Thanks.
@@DadsGarageDiagnosticSpecialist yeah might get more with the class action lawsuit but it's under warranty yet so can't delete the afm
Thank you so much! Fixed this exact issue on my short bus!
That’s awesome! Thanks!
how many pounds of torque the guide bolts are
They all have a different torque specification. I'd recommend getting a repair manual so you can have the correct specs. Thanks.
@@DadsGarageDiagnosticSpecialist i’ll have it in mind bro thanks
😂😂😂😂😂sopletea el lente ...te ca a quedar lindo...
Thanks for commenting.
Where did you do the exhaust side leak test? I have a 2018 Cruze, I was thinking to smoke the exhaust.
On this particular engine, the turbo mounts directly to the cylinder head all as one piece with the manifold. So there really isn’t much that can leak exhaust ahead of the turbo other than the gasket at the cylinder head. Thanks.
Can someone explain to me why my 2019 l5p and my 06 lbz both have the same injector 4 issue? Had to replace the whole injector on my l5p now not sure about my lbz?
Very unlikely that anything related is going. The LBZ has injector failures at high mileage intervals. Thanks.
yo i got one of those elm327 dongles and idk if mine is fake but theyre complete garbage. sometimes they work, sometimes they cause a canbus error and throw every code imaginable and put the car into limp mode. i would reccomend if anyone has that dongle, never leave it plugged in and only plug it in if you have a way of disconnecting the 12v battery like a cressant wrench since that was the only way i was able to clear all the codes and get the car out of limp mode with another scanner to clear codes.
That’s very interesting. I have an old Elm Scan 5 somewhere, but I’ve never tried it on one of these modern vehicles with multiple CAN networks. Thanks.
How much was that module?
It was about $300 or less if I remember correctly. Thanks.
❤❤❤❤❤
Thanks!
What an insane way they make you have to fill it up!!
Somebody somewhere had to justify their salary. Thanks.
what do you have to do after the repair to get the flashing light to go away?
That depends what level of restriction you are in and what the actual cause of the failure was. Check out some of my other Duramax videos. Thanks.
Phoenix has some electrical issues right now that I replaced the tail lights because I had it on warranty and the driver side tail lightI replaced some fuses, and that really messes things up. My tail lights driver's side doesn't work. My mirror turn signal doesn't work
Dang sounds like you need some diag. What kind of car?
it turns up my replacement LED tail lights has a broken circuit in it so I'm going to put my old OEM ones back in today
@danielb-c9100 LEDs seem to cause a lot of trouble on cars these days.
typical GM😂
Allowed slip on the TCC is the problem
All a band aid to the real problem. Allowed TCC slip in the programming. Zero allowed slip and it won’t shudder and wear out the clutch
Absolutely.
More GM JUNK!!!!!!!!!!!!!!!!!!
Thanks for commenting.
Great video! I did want to chime in that it’s a better practice to replace the sprockets. Even though the sprockets look “good” there is wear on them nonetheless from the stretched out chain. Using old sprockets will only wear out the new chain faster. Also, has GM updated the part in anyway? I remember the 3.6L had chain issues. You’d think they would learn by now
I don't know of any updated parts thus far. The early 3.6L engines had timing chain wear issues, but I've really only seen that when soccer mom/dad drives it low on oil and has minimum oil changes. The new 3.6L engines are much better and seem to be solid with good low end torque. I owned one for a while and it was great. Also I did request new gears, but the parts were not available within a reasonable time. I'd prefer to replace them, but you can't replace the crankshaft gear either so I figured it would be ok to re-use the cam gears if they didn't show signs of wear. Thanks.
engine with the timing on the back of the engine not even worth the time xD dirtymax xD
It's not a new idea. There are other engines that have the timing set in the back..... Ford SOHC V6 and VW comes to mind. Although the chain should last longer than the oil pump belt in my opinion. Thanks.
Looks like a truck I will never buy
exactly here in australia I have holden colorado rg with 2.8 duramax with normal oil pump and timing belt my previous car was isuzu d max3.0 and never problems with timing chain after 200000km even expensive cars like bmw or mercedes lost their quality
They sure do run and pull good when they're running though... Too much expensive technology for me. I'll keep all my old stuff running for as long as possible. Thanks.
The 2.8L seems to be very solid. I have seen basically NO mechanical problems with them, and minimal emissions faults. Just don't forget to change the timing belt on time or that could ruin your day.
I have a question. I watch both of your videos on the timing chain replacement. I have a 2020 Gmc 3.0 140,000 mi, just replaced turbo def tank and ecm 6500 bucks. 2 months later broken motor mounts and a growling sound towards rear of engine not on and off sound sometimes louder then others no codes but I'm wondering if you would think it could be a place to start timing chain or have you ran across that sound. Thanks
thanks for sharing another one of these poo16 repairs. i have to do mine and i will be pulling motor to do it. any tips or tricks you have learned are greatly appreciated. Looks like you aren’t pulling turbo and piping loose anymore? mine happened at 114000 GM will only prorate repair because i am over the 100000 warranty. the secondary timing chain on early 2020’s is the problem from what I researched. GM knows it and redesigned it, you will see little oiling holes in the new upper chain that are not in the stretched original one. Hopefully that fixes them for a reasonable amount of mileage. These should not be needing replacement at around 100000 miles GM should recall these engines and fix.
I fabbed up a home made tool from an 8mm socket and an allen wrench that I cut down and bent to get around the turbo coolant pipe bolts. I can't think of any tips in particular other than to take your time with every step and double check everything before reassembly. Group and label all of your fasteners step by step and take a lot of pictures. If this is something you've never attempted before it can be a very overwhelming task. Thanks.
Nice video. Would amsoil or the mobile one be better for this?
I would use the Mobil 1 because that’s what is specified, but I’m sure the Amsoil would be fine too. Thanks.
Want to say thank you. Change pump and may def light off. I noticed I was missing black cap inside pump on the big forward side.
That’s awesome! Thanks!
@@DadsGarageDiagnosticSpecialist Hello, I’ve been getting a P2BAA code on my 2016 Duramax Exhaust NOx concentration high -Low Reductant Consumption. Any help will be greatly appreciate it.
I have a similar issue with my 1994 k1500. It shifts out of gear when i have it in 2hi into neutral, But if i pull the shifter back a bit so its in between 2 and 4hi it usually stays put (still jumps into 2 or 4 occasionally) and now on deceleration, not every time, there is a humming noise until eventually it almost seems like it shifts gear and the noise stops. Sometimes theres a clunk before the noise stops. Cant tell if the noise is coming from the tcase. Do you have any suggestions on this.
If it is a manual shift transfer case that sounds like the shift linkage is out of adjustment or something is loose. They almost never go out of adjustment on their own unless somebody messed with it or there is something worn out and sloppy loose. Thanks.
Stupid useless video
Can anyone tell me the benefits of a dohc setup for a low reving diesel? Why couldn't they use a pushrod setup with a cam in block gear driven? Even if it was chain driven, it would be so much simpler and reliable then this setup. Perhaps it's for nvh.
Well the disadvantage of a cam in block design is that the intake and exhaust valves both share the same camshaft so even if you do have a variable valve timing system you're forced to adjust the timing of both the intake and exhaust at the same time. With a DOHC engine you can adjust the timing the intake and exhaust valves independently of each other which can allow the engine to breathe better under a lot of different conditions at both low and high RPM and loads. Also you can eliminate an EGR system by playing with the valve overlap and achieve the same EGR effect....as well as virtually change the displacement of the engine on the fly which can drastically increase fuel economy. Also this diesel engine seems to happily run all the way up to 5000 RPM and it seems to have good torque from low to high. Disadvantage of a SOHC or DOHC design VS a cam in block would be that the engine must be taller and wider to accommodate the valvetrain. Thanks.
@DadsGarageDiagnosticSpecialist That's true for a gasoline engine but this diesel does not have VVT. I just don't see a benefit to this dohc layout in this application.
@4wdiesels I guess only the engineers who designed it know the answer to that.
Was this covered or did the customer pay? How many hours does this pay under warranty?
I don't recall. As far as I remember, warranty almost never pays enough. Thanks.
How to get this
Heat shrink tubing from the hardware store. Thanks.
The most pathetic aspect of all these truck repairs is having to be forced to remove the cab in order to make access easier. Lends a lot of credence to the theory that the manufacturers would love for you to scrap it and buy a new one. The other thing I find ridiculous is the use of a wet belt inside where you also have a multitude of chains there anyhow. Insane!
I'm sure they used a belt to keep it quiet. The cost of repairs on modern vehicles these days far exceeds what many people can afford. They can't afford to buy the vehicle in the first place if they can't afford to drop thousands at a time for repairs. Thanks.
variable oil volume control strikes again.
I'm not sure about that. I was beginning to think it had something to do with 0W20 oil and extended oil change intervals. Thanks.
@@DadsGarageDiagnosticSpecialist the oil it uses is quite good and the capacity is more than sufficient for soot load. bobistheoilguy has some details about the diesel oil those engines use and the engine bearing designs for that type of oil.
