Not sure if it is meant to be there, but your first post still has an Engineers Name and Phone number.

Thanks for pointing that out. I removed it.

No problem they just recalled 2 l5ps for incorrect pulleys. But didn't think I needed to post it

can you elaborate more on the pulleys?

 

[mebob2001]

It's only 2 trucks they recalled one was stock one customer had. The idler pulleys they installed were in the wrong position or wrong one. I didn't read it because it's only 2 trucks I know I won't see one

#PIP5487: 2017 6.6L L5P Duramax Coolant Leaks - (Mar 16, 2017)

Additional RPO/s:
6.6 L5P

Condition
A customer may comment on a coolant leak, coolant consumption or of a low coolant message being displayed on the Driver's Information Center (DIC).

Cause
This may be due to cooling system leaks or an improper coolant fill procedure.

It may take a few engine temperature cycles (from operating temperature to cold) for the coolant level to show a lower than normal level.

Be sure to complete the current SI coolant system leak checks and verify there are no external leaks.

Reference the locations below to aid in locating external coolant leaks.

If no external leaks are found, refill the cooling system following SI procedures for filling the cooling system.

Evaluate coolant levels after a proper coolant fill is completed.


Correction
If the diagnosis has lead to external coolant leaks or a coolant loss concern check for leaks in the following areas:

Object ID: 4750018Click here for detailed picture of the image.

Welded flange leaking on the Exhaust Gas Recirculation (EGR) coolant return pipe. Refer to call out #1 in the above picture.

Object ID: 4747685Click here for detailed picture of the image.

Welded flange leaking on the Exhaust Gas Recirculation (EGR) coolant feed pipe. Refer to call out #2 in the above picture.

Another view of the leaking welded flange on the Exhaust Gas Recirculation (EGR) coolant feed pipe. Refer to call out #2 in the above picture.

Coolant leak at the O-ring seal of the Exhaust Gas Recirculation (EGR) coolant feed pipe. Refer to call out #2 in the above picture.

Object ID: 4749101Click here for detailed picture of the image.

View of a rolled or pinched O-ring at Exhaust Gas Recirculation (EGR) coolant feed pipe. Refer to call out #2 in the above picture.

Note: The leak shown above could only be confirmed after removing the front accessory drive bracket and alternator.

Object ID: 4750082Click here for detailed picture of the image.

Coolant leaking from coolant hoses at the Emission Reduction Fluid Injector (DEF Injector).

Please be aware of the following if there is a need to pressure test the cooling system:

Note: The radiator surge tank uses two different radiator surge tank caps. The radiator surge tank cap that vents pressure in the event of excessive cooling system pressure is located on the lower outboard side of the radiator surge tank (2). The radiator surge tank cap that is located on top of the radiator surge tank (1) is where the cooling system is filled and where pressure testing equipment is to be mounted.

Caution: The cap mounted to the top of the surge tank uses LEFT HAND threads. Turn the cap clockwise to remove the cap or counter clockwise to install the cap. Failure to turn the cap in the proper direction when installing or removing it may cause damage to the cap and/or the surge tank.

Refer to Cooling System Leak Testing (L5P) for more information.

there are pictures along with this but they do not matter for u guys, but new engine, new problems are starting to show, ive had one all ready with a fuel line leaking. as on drivers side which was stupid easy to fix, but I wanted to do the passengers and remove cooler

 

[M.A.M.]

More good stuff!

 

[Maxxer442]

So far I've had 3 of these happen...most notably the "Chuggle" in 3rd gear, and the low coolant level message. I'm sure over time they'll figure it all out. Thanks for the info!

 

[mebob2001]

Yup its all part of a new platform. The lml luckly didn't give me to many cool leaks or engine issues. Was mainly emissions. But the l5p will be way different and we will go through weird issues for sure

Great info.. THANKS!! I sub'd for updates to #PIP5480. Having that exact issue and took it to the dealer today, however it began regen as i pulled in the parking lot and they say they can't replicate the issue.

 

[Hauto383]

Fantastic information, gonna be on here all of the time now.... watching these like a hawk :nerd:


Thanks for the info and all the work to post these up

 

[mebob2001]

No problem. Haven't checked for a few days. But the thing I hate the .most is techs who do shit work. These trucks require attention to.detail to just throw parts at it. Or do improper diagnoses

Additional RPO/s:
6.6 L5P
Condition
A customer may comment on a Service Engine Soon Light on along with snow or ice build up on the air filter element or in the air filter box. Upon inspection technicians may find DTC P0106 set.
Cause
Air induction filter box may be out of position causing loss of sealing to the hood and/or the owner may not be using front end grille cover at below zero temperature conditions.
Correction
Confirm that the air filter box is in position, securely retained to the air cleaner bracket (1), that it is sealed to the inner fender (2) and to the hood (3).

Object ID: 4755855Click here for detailed picture of the image.
Proper sealing between the air box upper gasket (3) and hood can be checked by wetting the gasket, closing the hood and then checking for a contact ring at the hood mating surface.

Confirm that while the vehicle is operated in temperatures below -17C (0F) that the front end grille cover is in use by the owner.

The induction system on the L5P is designed to remove snow from the inducted air through the hood duct.

If the air filter box is not positioned properly it may compromise the sealing between the hood and the inner fender.

If the sealing is compromised snow can reach the air cleaner element along with warm air pulled from under the hood.

This can cause the snow to melt and re-freeze on the air cleaner element blocking it with ice.

In addition, if the vehicle is operated at temperatures below -17C (0F) and the front end grille cover is not used, snow can be pulled through the grill duct and over a period of time the filter may accumulate enough ice to reduce airflow.

So everyone knows. Part number change coming on the Injection pump. So this means an update or just a number change. My guess is an update

Be curious to know what the change is!

Would need both side by side. Chances are internal spring or something

mebob are you talking about the fuel injection pump here?

I'll be interested to see what the issue/change with the part is, if you find out let me know. Long story short I bought my truck beginning of February got to drive it for a total of about 5 days and it's been in the shop ever since. What they originally troubleshot as a possible lift pump issue which also incorporated metal fragments up into at least the fuel filter has now been deemed much more extensive. As of now they are pointing to a faulty fuel injection pump leading to them having to change out the pump, lines, high pressure rails, and one injector.

Well failures happen with every engine. I've even heard of an l5p with window in the block. It's a new engine that's life. But updates to this pump should be easier to.manage than with bosch. I honestly don't care whatever anyone says German engineering is fucking HORRIBLE. Dumbest fucktards on the planet. Had almost 20 years to fix lb7 injectors yet still they don't last long enough. All these crazy ways to fix cars came from those wonderful ideas. Now a days gm doesn't really care about how the engine goes togethor in a front wheel drive because we drop em out the bottem or there's JUST ENOUGH ROOM to.work. I can list of lots of repairs on gms that are crazy stupid. But they are nothing compared to voltswagon or audi. Like cp4 failures add a fucking keyway for the lifters and add extra hardening on the cam lobes. If that surface is compatible with ULSD it should NOT send failure through the whole system.
But my honest gut feeling gm has seen about 50 of these pumps fail this way and they wanna fix it NOW. Remember this engine is in military applications it has to be dependable.
