Along with the timing belt and water pump, do a/c belt, p/s belt, balance shaft belt, tensioner springs & pulleys, and there is 2x oil seals, one of which needs a retainer to be added since honda did not place them in from factory but it was later a TSB. If you havent done a t.belt change before be prepared to set quite the amount of time aside.
