Are there any videos such as U Tube available to assist in the disassembly ?

I'm one of them that might have veered away from your original inquiry. Sorry, I get carried away sometimes. Anyway, in regards to lifting the radiator and CAC out as attached unit, as stated before, you better be the HULK or, Arnold Scwhartzenagor (when he was a lot younger) to be able to do that. Some coaches, and the rear design specifically, might cause you to lift or remove them as a unit but, in ours, I was able to separate them and lift each one out separately.
R & R a radiator and CAC on these coaches is not to be taken lightly (no real pun intended). It's a pretty hardy task to get those boys out and back in. And, unlike front engine, tilt front end Freightliner Class Super Cs, which give you all the room in the world to do this sort of thing, working back there, and gaining access to all the components, braces, nuts, bolts, hose clamps, and a few zillion other attachment points is NO EASY CHORE. So, just in case you've never taken anything like this on, be prepared to use a few words that you might not want the neighbor kids to hear.
Now that I've done it, yep, I could most likely, if forced, have that radiator and CAC out, and on saw horses, in about 2-3 hours, as apposed to the 6+ hours it took me the first time. And, based on the trouble I encountered with ultra tight bolts, the little Allen-flat head ones that hold on fan hub, and a couple of other hard-to-get-to components and parts, I'd pull those two units in a heartbeat over trying to contort my old body into a pretzel trying to save not pulling them.
As for part numbers, as has been stated, if you call CAT with your specific engine serial number, they'll have the EXACT part numbers for your engine parts. Then, as others have stated, you may take those part numbers and call a NAPA or, what ever other parts supplier of your choice and see what, if any differences in prices there are. Good luck.
Here's what it looks like without them in the way.
