Which way does turbo coolant run?

At the risk of saying something rally stupid :angel:
If you turn off the heater, does it stop the flow of water and hence the water through the turbo, or will it just close a air flap.

I've removed my heater box and rearranged its orientation, and there is no valve controlling water flow to it. Just the flap :)

No. BadCo is correct on the heater part not having a valve - but expanding on it the 4BD1 has a bypass so even if you do have a valve on the heater pipes (many do in hot climates) you're not compromising the cooling of the engine or coolant flow for the engine.
