It is a Bus Depot German, from the same make of the original, water pump. I will check the shaft play and make a determination as what to do... Robert P.S.

If it is an authentic VW pump, I would not change it. If it is an aftermarket pump and you replace it with an aftermarket item, there is very little predictability with either. In my experience, the only positive thing about a Vanagon water pump is that they usually do not fail catastrophically, so there is ample time to replace a failing one at your convenience. Once, I had an aftermarket pump fail in less than 5 Kmi. In reality, it had failed early on with no signs of leakage, but I was too preoccupied with chasing an intermittent fan belt squeal to notice. It seems that what I thought was a squealing fan belt was the sound of the water pump impeller milling away the engine case due to too much end thrust. George
