I agree with Bruce...have the water pump done as well. I had a Honda years ago that needed a water pump so I had them do a timing belt at the same time, cost me like an extra $15.
They need to remove the pump to get at the belt (if i'm not mistaken) and they are generally designed to shit the weenie at the same intervals. Unless that is just what always seems to happen...spend HUGE $ for a timing belt and 5 days later the water pump goes.
