replace the water pump when replacing the timing belt?

Question

Hi,I have a 2000 Sienna with 95K miles on it. When replacing my timing belt, my local mechanic also suggested to look into the water pump. He said the same labor can be used to fix the pump as well if it is also worn out, and hence I can save money in labor. Is it common practice replacing a water pump when replacing a timing belt? Please share your experience. Any help is appreciated.Tony

Replace the water pump.  I replaced my Highlander timing belt at 101,000 miles and the water pump just started to leak from the tell tale drain.  The water pump definitely would not have made it to the next timing belt change.Paul.

Be sure to closely inspect your idler pulley and tensioner pulley.Make sure the bearings are ok..just my .02 worth

Your mechanic told you right.  If another mechanic wants to charge twice for the same labor to remove everything to access the water pump, scream.  In any case, always renew the water pump no later than every other timing belt change.  I'd also renew any tensioner and pulleys every other belt change.  The cam seals also need periodic renewal, maybe at this time.T
