From the procedure straight to the part number

Reading how to do a job is half of it. The other half is ordering the right part, which, historically, I have been spectacularly bad at. Wrong gasket, wrong length bolt, wrong side of the car.

So the manuals now carry an OEM parts catalog built in. You are on a procedure, you follow the link, and you land on the exact part numbers for the thing in your hand. No second tab, no third-party site, no squinting at an exploded diagram in another window.

The Special Tools page got the same treatment. Tools are grouped by category with filters, and a tool cited on forty pages shows up once, not forty times.

It is the difference between reading about a repair and being ready to do it. See it on any manual, for example the S13 parts catalog.
