[s-cars] Refilling Coolant

[Brian Powell]

Greetings,

I am finishing up with the RS2 goodies install on my car and will be 
refilling the coolant.  On my other two Audis, there is a bleeder valve 
you open near the firewall to the heater core and fill until it comes 
out of the bleeder.  Close it all up, run for 10-15 minutes, top off, 
and you're all done.

I don't see a bleeder valve anywhere on the 97 S6.  What is the best 
way to refill the system?  I drained it completely replacing the 
thermostat, turbo, etc.  The car being a 97 has always used the pink 
(G12 I think) coolant of love.

Cheers,
Brian
