What is a good flush procedure for the DIY guy without Vacuum filler?
Drain via Drain plug and radiator hoses, refill with Distilled water, burping via Bleeder valve, driving some small period of time? - Follow Bentley procedure basically
Repeat till only clear water is drained?

I initially didn't hesitate in buying Porsche coolant. I topped off maybe 1/4 - 1/3 pint many months back. The other day I topped of with about a 1/2 pint of Distilled water after getting new Cap. I looking in the tank I see green in the bottom. So Now I don't really know what is in there. Whether the previous owner switched to general coolant or not. Now I'm afraid to add my Porsche coolant. So it's time to flush and start with a known Porsche coolant
