water cooled...

[Jay Rabe]

You would want to tap the supply from something below the headgasket, this
is a restrictor to the coolant flow, and causes a little higher pressure in
the block, thats why the use the  freeze plug.  I think the 'special' freeze
plug is under $10.  If you hit the side of a freeze plug with a big
screwdriver and a hammer it will usualy spin sideways and its easy to pull
out.  If they are rusted in a BFH will usualy pursuade it.  the return can
tap in anywhere above the head gasket.  Mine is connected in the water neck
coming out of the head.  I wouldn't return it into the head, keep the heat
out. the water neck (on the head) is where audi normaly returns the line.
Anywhere between this neck and the radiator (top hose) is ok.
