Here is a basic cooling flow diagram I made up to donate to the forum. If anyone wants one in a different format, PM me. Get the MMI manual and accompanying notes for more complete information.

I am not at all familiar with early model A4s. Please correct me if I am wrong with either of these diagrams, since I am not an expert on engines.

UPDATES: 11 July 2010 - slightly revised late model diagram, and added early model draft diagram.
