Bob,
   I guess I would not suggest you carry either but
rather some odd collection of hoses and a spare belt.
Both the waterpump and alternator should give you some
warning before failure.   Listen to the engine and
look for leaks or coolant loss and never ignore those
red lights.   gary
Perked me up!  I've been thinking about buying a water
pump as a spare.
The
first one lasted about 150,000 miles before it
self-destructed, but my
limited experience with other vehicles is that 150K is
unusual.

I'm concerned that either the water pump or the
alternator can be
catastrophic failures far from home, so thinking about
buying one each
to
carry as spares.  I'd be curious to hear other listees
thoughts.
