It's controversial, but I am with the people who believe the water pump
should be changed at the same time. Some have kept the original water pump
over 200K miles, but I don't think that's the smart way to bet. It is
reasonably priced and the labor to change it once the timing belt is off is
small. Same thing on the crank and cam seals - cheap and easy at that point,
although they are a rare failure. Also the seals won't destroy your engine
if they fail, like the water pump can. My belief was sealed when a member of
the Volvo group reported his water pump seized a year after he had the belt
replaced, and it cost him bent valves. Seals optional, water pump not.

There's also a belt tensioner - two in some engines - that is probably
getting pretty ragged (the sealed bearing will sound like an old roller
skate wheel) after 100K. It is in the same price range as the water pump,
but if you can afford it the peace of mind is worthwhile.
