    I have all but finished my head gasket job. Everything is reconnected except I'm working on the wire plugs and hoses. the electrical plugs are pretty simple, the kraken kinda folds itself out neatly.

    I am really struggling with the hoses. Some of them came fully off while I pulled parts off and I can not find a list anywhere of what connects with what. I definitely don't want incorrectly placed hoses to ruin my last two weeks of work. I do not understand the black and white diagrams at all. Does anyone have just... a simple list, like "water pump nipple connects to front lower EGR cooler nipple" in that style?

    How about: take pictures of the components you're scratching your head over, and responders will (hopefully) take well-lit, pictures (preferably flash?) of the same area, showing the hose shape and routing.

    Appreciate that's easiest (for responders) when nothing more than raising the hood is needed. I'm game to pull the intake air box and snorkel if that's needed. :)

    Also, have a look at this page:

    This is one of the links there (1603, Radiator and Water Outlet) "might" have it all, not sure:
