I'd be inclined to suspect the thermostat or a plugged radiator before messing with the water pump. If you pull the lower radiator hose and dump water in the top, it should flow out with ease. The thermostat is unlike US designs. In the full cold position it blocks flow to the radiator but directs full flow through the block and heater. In the full hot position if forces all the flow to go through the radiator.
