hi & welcome. your coolant loss could be the water pump leaking. you dont always get a leak when you pressure test them. try popping the cambelt cover off and looking for a telltale coolant stain around the pump.

well folks we removed the bumper there this evening and ran the car for an hour or so , and we seen steam just near the bottom left hand side of the rad , so with closer insptection we then seen a small trickle of water from rad , so happy to say i got new rad on ebay ,so not as bad as i feared after all
