Sure, why not the Water Pump.
This year I have already replaced the Alternator, the Power Steering Pump, the Harmonic Balancer, one of the Serpentine Belt Idlers and the Supercharger Drive Coupling.
The Water Pump and the AC Compressor are the only belt driven items left to replace.

It still appears that the leak is @ the Radiator, the Elbows and the Water Pump are to far back.
I just do not understand why it does not leek under pressure.
Maybe this weekend, I can watch it closer and actually see the leak.
