Evening all... Just bought myself a 97 1.6 A3 in bright red - lovely car with an S3 bumper and wheels (I think!), but had a failed head gasket. I've just finished replacing this, but I seem to now have an air lock in the coolant system somewhere, and I can't find a bleed valve or radiator cap anywhere to get rid of it. Does anyone have any helpful hints on whether there is a bleed valve somewhere, or advice on how to get this flaming air lock gone? Picked up some good styling tips so far from browsing through this forum, and now just keen to get the car on the road and get playing with it!! Thanks, Andy.
