I think, as far as I can tell, the water from the cooling loop comes out of the grills on each side just above the ventilation plate. Your description of the cooling system I think is right. My thermostat has 60deg stamped on it, but the engine should run fine (although may use a little more fuel) even if you take the whole thermostat out, which leads me to think you shouldn't really ever have a problem with an engine running too cool, only too hot.
