hI Neil,
Did you see my post about removing the water pump AND housing as a Unit,
from the side of the block ??
It is NOT necessary to remove the intermediate shaft sprocket or timing
belt or any of that,
I'm looking at one of my Inline 4 Vanagon configuration engines right now ..
VW designed so you don't have to touch the timing belt to replace the
water pump.
You might have to remove the alternator bracket to get at the w. pump
housing bolts . No big.
re your water pump ..
when you had the belt area apart..did you to the normal 'turn to check
for smoothness and looseness' on the water pump ( and alternator )
since that was an ideal time to do that test/inspection ?
like I like to say .."It's ALL about the Workmamship."
sounds like you're having a great trip !
Windy Grit.....especially if gusty ...nasty stuff, can get in everything.
happy trails,
Scott
