Either way I've seen t/belts on 5VZ-FE motors go well beyond 100K, although I've also seen them pop a little over 100K... depends on how much of a risk taker you are

Toyota has amended the schedule for all car v6's to the newer schedule of:
90,000 mile belt change & replace the water pump @ 90,000 miles with the timing belt for preventative maint.
This was amended from the previous schedule of:
60,000 miles inspect timing belt, inspect every 15,000 miles indefinately until it needs changing. Change the pump every other timing belt interval.
Because the truck engines are the exact same thing. I suggest that everyone follows the new schedule regardless of the original schedule. This will simplify the timing belt question/answer for all time.
Replace the timing belt & water pump every 90,000 miles.

Ok, not trying to start a fight with anyone on this board... so please don't take offense, these are all opinions and things I have witnessed in this line of work....
the water pump issue seems to be up in the air as to when to change it and what is smart preventative maintence. I have previously stated in this thread about the FIPG issues with the original, factory installed water pumps. The reason for replacement was not normally because the internal operation of the w/pump was faulty, it is 90% due to leaking issues. Once replaced and if replaced correctly there should not be any reason to continue with preventative replacement. I've seen a hand full of 5VZ motors with 200K+ miles who have not replaced their w/pump since the first replacement and have no problems... But I suppose it is personal perogrative on what repairs are done to their veh.
