You could put in a new pump in and it could fail the next week, but its super rare for the pump to go.
Also if your mechaninc is doing all the timing stuff now dont replace the stuff at 105k do it at 150+k

So, the correct advice would be to replace the 4 timing belt pulleys again at around 100k since it is getting done at 50k now. We need to think about "smart" maintenance not some thing about look how long I went on the timing components... If the timing belt pulleys are good up until you do change them, then the belt should be good for at least 100k miles unless there is contamination from outside debris, water and an oil leak stuff like that. Timing belt components are cheap compared to an engine so be smart and do the pulleys sooner

Part of the problem is people not searching around to get parts a whole lot cheaper compared to the dealer... The water pump can cause a huge problem if lets go and you don't catch it fast enough. However, part of the problem that people run into is letting their coolant go for too long. We have to remember that the coolant is water lubricates the seals of the water pump and if the coolant has been in there too long then the seals of the water pump will suffer.

So to the OP, if the pump looks good and there is like no play, then don't replace it, but I would replace it at around 100k along with the 4 pulleys again but leave the belt until around the 150k mile mark.
