Does anyone have a diagram of how the cooling system hoses are connected on the 968? Neither the workshop manual nor parts manual show all the hose connections. I am particularly interested in the connections from the overflow reservoir, through the throttle body, and then under the intake manifold to the rear of the block. Does the coolant flow into the block or does it simply flow to the heater core?

Thanks for your inputs.

The coolant neck that is in the back of the block recieves the coolant back from the heater core. Lets think about this. The heater control valve opens and sends hot coolant from the waterpump through the hardpipe that is mounted above the exhaust header. The coolant pipe then goes into the body through the heater core and back out to the back of the block to the coolant neck.
As far as the fittings coming from the resevoir, the coolant goes through the throttle body to warm it (emissions related) and then connects to the side port of the coolant neck on the back of the block.
That is how I see it.
