So you got me curious. Where are you seeing those lines with clamps?
Teh oil cooler lines appear (stupid manifold blocks your view) to be rubber lines with pressed on fittings as per the detail (#2). The lines lead from filter canister to in front of the left front tire. Cant see anything from above. Mines put away for the night (as am I) and I dont feel liek crawling under it right now. Maybe this will help.

There are trans cooler lines that traverse the lower rad that have hose clamps connecting rubber to hard lines......maybe that is what you are seeing???
