Proper coolant for these cars
 

First off, I have searched both this board and renntech and there seems to be a bit of confusion on whether to use the Dex-cool (OAT formulation) compatible product or the HOAT formulation (Zerex G-05, etc). I perused DJ's post where he showed a pic of the G-05 he swapped in after making the mistake of using the plain old green stuff, but the Renntech thread clearly stated to use Dex-cool and the Zerex website recommends Dex-cool for all VW, Audi, and Porsche applications after 1996.

So, which is the correct coolant for those that know?

We touched on this subject yesterday. Somewhere in MNBoxster's response, I think you'll find the answer you're looking for.

This is all excellent reading. It would seem the proper coolant for us is the Dex-cool variant. Someone correct me if I'm wrong please.
