Water Distribution Block

[dave205 19]

Does anybody know which connections are which on a 2.0 8v turbo engine on the water distribution block on the back of the engine?

 

Obviously the returm from the rad is an inlet to the water pump and the pump pushes water up through the block, but what about the one that goes to the turbo and the one that goes to the matrix?

 

My header tank it tee'd into the line between the head and the matrix is this right?

 

I'll add pictures later when i get home.
