This CD has these listed sub sections and also "thumbnails" of each page & "bookmarks" listed by GM "Group #'s".
I'm not sure on the "search" function, as I go by Group then pull up the picture and find the part, then part #.
I think the PDF was created from scans of an original manual.
Listed in 16 different sub sections such as:
Engine - Clutch
Cooling - Hoses
Starter motor - Wiring
Fuel supply - Ignition
Brakes - Exhaust
Transmission
Drive train
Interior
Glass
Exhaust
Emissions
There are almost 1500 pages in total.
I find it very easy to find the right GM "Group" then "sub -group" such as "Engine, Cooling etc. Just click on the Group your interested in and it pop's-up.
I find it much easier to use than the last "paper" GM parts book I have. Also. you can zoom-up any page for a more detailed look and also print it out .
I have the CD for the ZR-1's and have found it to be a very valuable tool! :dance
