I looked on realoem and google searched, what is the part number of the coolant hose that connects to the bottom of the top radiator hose. It runs along/under the charge pipe.

Not sure what this feeds either. Mine is starting to deteriorate and needs placing soon.

I did my OFHG the same time but you'll definitely lose some coolant.

drain it first unless you like to make huge messes

I recently broke the connector to the breather line, the connection on the other side of what you are talking about. Got both hoses (breather and upper radiator). Wasn't difficult, and I didn't lose much coolant, but enough to make a huge mess.
