Dealer states that I have to buy the supplemental manual for my engine. You're telling me that in order for me to know when to service my vehicle and document it, I have to buy a $60 book after I spent $55k on a pickup?

 

Is this true? I have the owners manual for all of the gasoline versions, but not the diesel.

Mine also came with both the regular owners manual and the 3.0L supplement 

(the 6.6 has a different supplement)

 

Fwiw, I always use the pdf version, since the 'hot links' in if make it easier t jump around in the document.

 

PDF's for 'main' and 'supplemental' manuals are free and available for many years of vehicle from GM's websites

Sounds like your dealer lost or gave your supplemental manual to someone else and wants you to pay for replacing it.....

 

You should get all of the paper manuals with your truck for FREE.

I spoke to the customer service manager and they insisted that I had to purchase it, which I refused. She eventually gave in and said that "parts is ordering one and mailing it to me", but she still said that they don't come with one. I again argued the point of needing a freaking service manual and she didn't even care.

 

This dealership also lost my 2nd key, and are currently mailing a replacement blank that I have to take to my local dealer to have cut/programmed. It's been 24 days since I purchased my brand new vehicle and I still don't have a service manual or spare key. Very upsetting.

The diesel supplemental owners manual comes with it 1000%.

It's not a service manual that is free -- it's an owners' manual.

 

Definitely not the same thing. 

 

Owners manual and diesel supplement can be downloaded free... 

Here's a copy.

There is an Owners Manual and a Diesel Supplemental which is the service manual. 

 

Thanks everyone else for confirming my suspicion. I'll definitely never go back to that dealership.

Call it what you want, but the supplement is the approx 50 page booklet in the link above. 

(mine came with the paper copy of what is linked)

Just like the owners manual, the pdf uses hotlinks which make it easier to navigate around the manual.

 

It is most certainly not a service manual. 

 

 

If you went in demanding a service manual (rather than the supplement) I can understand where the issue arose.

 

 

OTOH, I gotta agree that some dealers are not worth visiting

-- although sometimes even good dealers have salespersons that are a waste of air.

Again, it is the service manual for the 3.0L Duramax. Why are you arguing?


Since you are clearly hear to troll me, the definition of a service manual: Factory service manuals are the manuals provided by manufacturers which cover the servicing, maintenance, and repair of their products.
I have the Owners Manual, which does not state anywhere in it anything about the maintenance/repairs on my 3.0L Duramax. The supplemental, for the 3.0L Duramax which you linked the PDF to is the service manual. It contains the documents needed to service my engine and when it needs to be completed. 
So, kindly go be a keyboard warrior somewhere else.

uess then, by your definition,  the regular manual is also a service manual - since it includes maintenance info as well as how to operate info?

 

Service manual has stuff like wear limits for journal bearings, torque specs for crankshaft mains, sequence for retorquing the head after head gasket replacement etc etc.

 

Supplement has the maintenance schedule, oil to use etc etc for the 3.0. 

Some sort of stuff the regular OM has for the gas engines. 

 

I've had 4 duramax trucks LLY, LMM, LML,L5P and LM2

Every one has included what GM calls the Diesel supplement for the specific year/engine.

 

None have included a service manual set, but I have coughed up and bought one set.

The set weights about 50 pounds.  8.5x11 or largr pages, and about 20" of shelf space.

Most definitely not include with a truck.

 

 

You should have got the 3.0L diesel supplement with you truck. 

You should not have got a service manual.

 

 

If you were asking for the 3.0L diesel supplement you dealer rep is the problem. 

If you were asking for a service manual, that is why there are confused/resistant.

 

 

If you want a paper copy of the document in the link, you need to refer to it the way GM does == 3.0L Diesel Supplement.

GM's name for it is right there on the front page: 

 

They've been using that naming convention for 20+ years.

The "3.0L Duramax Diesel Engine Supplement" should of been included with the other booklets, yes it does include when suggested servicing and such but it is "not" a Service manual.😉

 

This is what should of been included like others have suggested

You realize that this is an internet forum with customers that don't know books like that even exist, right? Any competent person, like everyone in the conversation except for you, understands that a the owners manual and the supplemental are both service manuals since they both have the steps for CUSTOMER MAINTENANCE in them. Now gtfo out of here, your input is not wanted or desired.

I now understand why the dealership was having a hard time understanding what you were asking for. 

 

If you went in asking for a service/repair manual, you were wrong. If you went in asking for the supplemental owners/maintenance manual you were correct.

 

In the repair/service industry, there are owner/maintenance manuals, which should come with new vehicles for the owners. Then there are repair/service manuals, which the SERVICE departments use to REPAIR the OWNERS vehicle when it's above the pay grade of customers that only MAINTAIN their own vehicles. 

 

Now gtfo of here, now that you know the nomenclature of what your after.

Well this thread has run it's course. Answer has been provided.

 

Mine came with the supplemental. PDF version is easier to use.

 

SERVICE MANUALS you do have to pay for since they are extensive repair information.

 

Contact GM directly to obtain the supplemental

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      By Grumpy Bear · Posted

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
