Report: Coolant loss may be a sign of internal engine problems
Porsche Boxster Problem
To ensure engine longevity, coolant loss and overheating issues need to be resolved. Coolant loss—sometimes slow and accompanied by white smoke—is often a sign of internal engine problems. The proper coolant fill procedure must be followed.

Persistent cooling problems finally traced to an engine problem (crack?). Apparently building-up too much pressure in the closed system and blowing-out radiator hoses one at a time. Persistent condensation build-up under trunk near coolant resevior. Unrepairable without dropping-in a new engine.
