4AGE Cooling Circuit.

Can anyone help provide a good descrption or diagram for a 4 AGE cooling circuit. I have the Haynes manual but it doesn't answer all my questions. In particular:

Where to connect the heater matrix?
How/ where to connect the expansion tank?
Do I need a valve in the loop for the heater matrix?

Note that I'm using the thermostat.


Thanks

you can see the large top hose on the left and the smaller pipe on the right (shown blue above) that goes off to the top of the header tank(golf mk2)

The 2 red hoses go to the bottom of the Tiger rad. The tiger rad had an inlet at the bottom left and in the middle of the bottom tank. When I swapped to the polo rad (only 1 outlet) I put in copper 'T' in the bottom hose so the middle hose went back up to the bottom of the header tank
