20 valve turbo coolant loss

Don't most head/head gasket issues result in greater pressure in the
cooling system?  

I'd look first for something that leaks while the engine is running.
Neighbor's Envoy did the same thing, but there was never a puddle under the
car where he parked.   He let it idle after a good warm-up drive and
discovered that when hot, something in the water pump would expand enough
to allow leakage that only occurred while the engine was hot and running.
