[s-cars] Antifreeze ? Anything enique?

[Rich Assarabowski]

Bruce:

Use Pentosin G001100 (popularly known as G11), it's the blue stuff.
It's also sold at VW dealers under their Autobahn label.  I bought mine
at Blaufergnugen, they currently have it on special at 10% off.
Draining procedure is outlined in Bentley (drain radiator, remove
thermostat), be sure to replace the thermostat O-ring with a new one.
Use distilled water, not tap water when making your 50/50 mixture.
Pretty straightforward on these cars.

>Is there a  "special" antifreeze that must be used in our Audi's?  My
car is a '95.5 S6. (ohne Silicates, aluminum engine >components, et
cetera) Any BTDT with this DIY issue?  Flush techniques? Where to buy?
