The 300tdi water pump is a joke really, THAT PATHETIC little tapered roller bearing at the front sitting in a nylon cage, with bugger all room for grease!!!!, and that bloody great pulley bolted on, and that bloody serpentine belt with a shocking tension pulling directley down on it!!!, Luv the tdi ,but that water pump set up would have to be the worst of any motor, ever built.
Cheers Sumo
