Who gets rebuilt water pumps for Vanagons or Jettas? Thoe worst I have
seen is the GMP brand. Stamped metal impeller that just does not move
enough water at idle. I have never seen a plastic or composit impellar for
a VW application.

By the way, if you get a "rebuilt" water pump then be sure to check
the impeller before you install it.  I bought one for a Jetta years
back and the impeller had visible, fairly significant cavitation
pitting right out of the box.
