My Volvo 850 Turbo blew coolant yesterday - right through a crack in the cap on the coolant overflow tank. Now I am spooked into thinking I should be doing the same on the quattro... Do the 4KQ engines run as high a pressure in the cooling systems as the turbo's do? I wound up replacing the thermostat too - not sure what failed first and was wondering if Audi's do that too.

the one's that have gone bad on me start seeping at the rubber o-ring first

If you need a cap, I have a good used one for $5 plus shipping.
