Need help on isuzu gigamx

[Robin10]

I'm looking for this item. It is leaking and I have no ideal what it is called and what it does. Can someone please help? Thank you in advance.

I think that you'll have to get better photos unless there is someone here who is extremely familiar with these trucks.

Which engine does it have? I'm curious about the 600hp V10 engine.
