Overheating problems

[charlieb]

i think you have answered all your own questions! seems like the waterpump is failing. noise(bearing)+ leaking = failure.change out the pump.i would purchase another brand after market 1.

Is it possible for the timing belt to turn the water pump gear, but the impeller on the other side of the pump is not spinning? As in, could the shaft break? Because even with a leaking/squeaking bearing, I'd expect coolant circulation from the pump...right?
