159 2.2 jts overheating/water pump failure

Hi all.
Im looking for advice on my brothers 159 2.2 jts. It overheated on a long journey and he had it towed home and hasnt driven it since. It doesnt appear to have any leaks, no signs of headgasket failure, removed thermostat and it appears to be opening freely, rad is not blocked, no air locks evident. Once engine is started the water doesnt flow and the pipe going from the rad to the engine block fills up with steam.
I am assuming the water pump has failed. Is there any other way to confirm this?
If it is the pump does anyone have any experience of changing it on this engine? Where it is located etc. I think its driven from the chain but i havent been able to find anything on the 2.2 engine.

Help and advice appreciated.

Water pump on the jts is driven by the ancillary belt (Pwr steering, alternator etc) and is on left of engine (looking from front)
