If your waterpump has gone south to the point that you are tellng your
mechanic about it, better stop driving it till you get your bus depot water
pump in the mail.I understand the replacement is about $600.In addition to
this price, if you keep driving with a bad pump, the pump will grind the
case away where it will have to be repaired too.Big  replacement job, but
can be done by you if you know a few things about mechanics,and have the
time.Search the archives to get a feeling of how this repair goes. Tom
Carrington has a article about this. I would compare that to any other
articles you can get. Try www.vanagonrescuesquad.com . They may have this a
write up under BTDT.
