Hi,

For the water pump replacement you will need the gasket  for the upper and
maybe lower coolant cross-over pipes. Also on the pump side of the upper
coolant cross-over pipe is a o-ring which would be good to replace.  These
gaskets and o-ring were not included with the water pump I bought from bus
depot.

Luckily I had these gaskets and o-ring in the spare parts bag that came with
my van.

I RTV'ed the gaskets and o-rings like it says on Tom Carrington's web-site,
just because this is such a big job and I didn't want any leaks.

Also it would be a good time to replace the 2 short pieces of hose that you
will see. I had only bought one of the replacement hoses from BD so I had to
go to NAPA to find something to use for the second one. NAPA 1" hose is a
PERFECT match for the inner diameter of the stock hose  I bought from Bus
depot..  Plus the BD hose was $6 while enough hose for both from NAPA was
less than $1.   I measured a 1" Gates brand hose at a different parts house
and it was a little bigger ID .

I soaked all the bolts and nuts I would have to loosen with Kroil
penetrating oil.

I replaced the thermostat while I was there also with the stock german
replacement from BD.  It runs a little hotter than the one that was in
there, but that should make the van heater output a little warmer in winter.

This is a big job, I can't imagine head replacement would be too  much
worse.

 IMHO it is suited for a person with a little above average  mechanical
abilities, and at least a full day to do it.
