OK, so now we know
that I either have original porsche green coolant (8+ years and 93K) very likely or some undefined green coolant - either way it is time for it to go. This is dead coolant walking.
And I don't mind paying for the Porsche coolant - becuse I know believe in the magic of placing a Porsche label on a plastic jug.
But not sure I want to pay the dealer to run hot water throught the systems. Even though only your authorized porsche mechanic know what end of the hose water comes out. So how - without the proper equipment can you get a good flush?
Just keep filling with distilled H20 - drive/idle - drain and repeat ad nasuem?
