How And What To Use For A Cooling System Flush?

[WARDHOG]

I came back from a trip to Tucson, AZ and lost all coolant due to a bad pressure cap popping off too early. I want to replace the new fluid that was put in Tucson with distilled water and Porsche A/Freeze to make sure I don't have any corrosion in the future. So, what is recommend for flushing out my MY 2003 C4S and what is the proper way of do this task? I know how to flush cooling systems on regular cars but, a Porsche isn't a regular car. :help:

TIA!

The best way to perform this is with a "coolant exchanger" machine. The machine gets hooked up to the engine coolant hose and you visually watch the new coolant go in and the old coolant come out. Usually you exchnage it past the specified volume, so you get all the old coolant out. I doubt there is any other way to do this, especially with the radiators up front and all the plumbing. You can do a Google on Coolant Exchangers, companies like RTI and SnapOn sell them. Tell us how you make out.
