Motorpool Gremlins: LMTV 1/4" ID Hose from Radiator Fan to Fan Shroud?

[Crapgame]

Hello, I don't know whether the neighbor's cat was up under the cab or if it was just time for it to break, but when I started up Mad Max this AM I heard a slapping sound after a few seconds. I hand pumped the cab tilt to access the power pac, but the only thing I can find is a black hose approx. 1/4" ID attached to the front of the radiator fan hub, only long enough to reach some kind of breather fitting in the top of the fan shroud.

Any ideas before I disassemble the fan shroud?
