I actually purchased a diesel diagnostic laptop from TruckScanners.com, and it came with CAT SIS installed, which includes Caterpillar service manuals covering everything from older engines to the newest models.
From my experience, it wasn’t just a few manuals either, it had complete Caterpillar documentation, including disassembly, troubleshooting, testing, programming, and maintenance manuals across engines like C10, C12, C13, C15, C18 and more, similar to what people are sharing individually in forums.
That’s why I found it useful , instead of hunting down manuals one-by-one, everything was already organized inside CAT SIS.
This is the one I purchased:

It came ready to use and saved me a lot of time searching for manuals and troubleshooting information. Hope that helps!
