Does anyone know of an on-line source that would show isometric illustrations of all components in the engine compartment as well as
the name and purpose of each? I hate guessing about what I'm looking at and the Haynes Manuals with their arrows (pointing in the general direction of where a component is supposed to be) drives me nuts. Are the Chilten Manuals more specific or should I be looking for an Isuzu technical manual? There's a bunch of stuff in there that must serve a purpose and I have no idea what it is.
