[200q20v] radiator exposure to fire extinguisher chemicals?

[Glen Dustin Powell]

Was dry chemical. The rad was new, as was just about everything else.
  The rad core developed the same white dust from oxidation as did all the
other under-hood alloy pahts. Anyone know if OEM made-in Germnay (KEG?)
(AEG?) replacement rads with the plastic tanks have alloy or copper cores?

Thanks!

Dry Chemical?  Dry Chemical fire extinguishers are not allowed around
aluminum aircraft, this I know for sure ...

How much of the radiator is aluminum? fins? tubes are probably copper.

If it's the original one would it hurt to change it given the track record?

good luck.
