As the coolant passages run at each end of the heads, the usual head gasket symptoms don't usually happen so you won't see oil and coolant mixing, although you might see steam out of the exhaust.
Take the spark plugs out and if any look steam cleaned compared with the others, there may be a weep around the outside of the line on that cylinder. If when started from cold it initially fires up on 7 with the last one chiming in after a few seconds, that again would suggest a slight weep on one cylinder. The cooling system will pressurise when hot but if that pressure disappears once it has cooled down, then there isn't a weep. The top hose will get hard when it is hot but if it is then left overnight and there is no pressure there, you're OK.
There's lots of places where coolant can leak from, heater core O rings, the multiple hose joints, etc, so losing coolant is more often leaking rather than anything else.
