If I have a 2001 Boxster and the coolant looks green and not in the pink or yellow family. Then it must have been changed (by previous owner) to a non-porsche coloant.

By color alone, I cannot determine chemical makeup - but probably phosphate free (most are) however likely not silcate free.

Best game plan - have it professional flushed. I have tried twice and can only get about 2 gallons out. So some coolant seems to always remain in the system.
