Found it on the GenI in ASA. Hate it when those 2 are right... P/N MB272294 Valve, Heater Water. It's in one of the pipes that goes into the heater core itself. The one with the little stubby piece of hose on it.

Oh well, it was fun while it lasted. Guess I'll go ahead and put the compressor on now....
