Having finally tied down the oil leak (failing front crankshaft seal), the windshield washer reservoir is now leaking. It seems to me that it can be one of three possibilities: a cracked reservoir, a loose hose clamp, or the washer motor itself. Is there a logical way to diagnose the leak? It seems as though even someone as ham-fisted as me should be able to make this repair by myself.

On a related note, when the mechanic fixed the front crankshaft seal, he also replaced the radiator. Would it have been necessary for him to mess around with anything connected to the washer reservoir? I don't believe that it was leaking prior to the other repairs, and am curious as to what might have happenned.
