cooling system questions and Dexcool

[walian at att.net]

Pasquale,

   The place were I take my Audi to said that the GM dexcool is not compatiable with the audi g12 antifreeze. One is orange/red and the g12 is pink. On something like this I wouldn't try to swap coolants. I believe I paid about $15 for the g12 at the VW dealship.
