Should I have replaced the water pump, when I replaced the timing belt, and the serpentine belt? The dealer told me it wasn't nescessary. Kind of concerned now though. This is on a 03 tundra 4.7 v8

i cant believe the dealer told you the truth, must be the last honest one, how many miles are on it? It kind of sucks now though the truck is all back together. maybe check some other forums or google it

I Have 98,000 miles on it now

Yes, I would have changed the water pump at the same time since it is pretty much right there and you will only be paying for the cost of the water pump.
It is a "damned if you do, damned if you dont" situation, if it is not leaking.
However, to avoid maintenace costs between your next timing belt, it is best to do so.

Yeah I asked the dealer, and they said there was a seal that they would replace if it looked bad. But I know on my old 89 extended cab, when i did the timing belt ,I did the Water pump too.

Yes, they are typically done together. You dont HAVE to. But general consensus is to do it at the same to save possible service costs. Also, the seal alone doesn't dictate the condition of the water pump, it just means its not leaking...yet.

I replaced my t-belt on Saturday. My w/p was not leaking, but showed signs of seapage. I had 109,000 on mine so it was an easy decision to replace the w/p too.

Yeah I should have known better. I just hope that if and when the pump goes, it don't really mess up my engine. Then that dealer is gonna get a peice of my mind 4sure

It won't mess up your engine as long as you don't let it overheat. When it starts to fail, it will likely start leaking and you will notice coolant under your rig. You have to really ignore it for serious trouble to come from a bad w/p usually.
