I followed the instructions from here Pelican Technical Article: Boxster Coolant Replacement / Boxster Coolant Flush - 986 / 987

I believe it was run the vehicle a bit and use the bleed valve located near the reservior cap. Allow vehicle to cool down. Turn vehicle on, but not the engine only electric. Turn heater on High. Take reservoir cap off. Then take off drain cap. What ever the link says, is the exact instructs i followed.

I'm going to try the EZ Out, but first have to order the new cap, hose clips, fluid, cap, and i'm almost certain i need a new reservoir now. I took it (the car) out twice and stopped before it overheated. both times i had to add a half gallon of distilled water.

I also have black flakes in the fluid :-<
