Gold mine. Thank you

Unbelievable source of info.

Odd that the SM file size between the 2025 and 2022 5BW is so different. 2022 is 400+ mb while 2025 is only 21mb

This is absolutely amazing. Has anyone found the official/legit PARTS diagrams info anywhere online?

Some of the parts wholesalers have a pseudo-catalogue, but its not everything and lacks a lot.

After getting frustrated with the manufacturer websites dropping the ability to access full parts diagrams, I found repairlinkshop.com which is a resource that is likely used mostly by independent mechanics. You can sign up for an account for free and look up all the parts diagrams by year/make/model or VIN for cars back to 1992. If you add a part to the cart, you can see the manufacturer part number (very useful for shopping around). You can even purchase parts through local dealerships at discounted prices via the site.

Regarding GM service manuals, helminc.com has been the main authorized resource for printed and digital copies. However, they do not currently carry service manuals for any CT5 models. What I do now for new GM cars is purchase a 3 day subscription for $22.00 to the ACDelco Technical Delivery System (acdelcotds.com) which is the system the dealers use. This system contains the most up to date service information including all bulletins and campaigns. Then I spend the 3 days downloading every section of the manual to organized PDFs (mindnumbing, but great once you have it). You can’t use hyperlinks in this format, but since I use the title of each document as its filename, finding any required section is easy. Since I am taking delivery of a 2026 CT5-V Blackwing Deep Ocean M6 later this week, I completed this process last week. The entire service manual was just under 4600 PDFs.

Wow 4600 PDFs for one manual, that's insane but sounds totally worth it for the complete info!

So.... Uh.... Care to share those PDFs?

Unfortunately I can't per the agreement with ACDelco TDS.

I provided the info so others could be aware of the availability of the ultimate GM service documenation for a nominal fee.

As an aside, when you purchase the TDS subscription, you have access to all GM cars by year/make/model or VIN during your access term. The VIN is useful since the site will generally not show you, for example, service information for engines and transmissions or various RPO codes that do not apply to your specific car.

So I took a look at RepairLink, but it requires you to sign up as a business, enter a business name, etc. How did you get past that?

For the business name I used my own name and called myself owner/proprietor. I actually have 2 and 4 post lifts and have fully serviced my cars and some family members' cars since 1993 (absolutely everything except tire mounting, balancing and alignments). So I almost function as a real shop .

I imagine you could feed the PDFs into a LLM and have them rename them all for you. Or generate some sort of scripts to do it.
