The water pump may fail resulting in engine overheating and possible timing belt damage. Overheating and/or timing belt failure can result in very expensive engine repairs. As a precaution, it is recommended to inspect the timing belt and water pump at regular intervals.

The water pump failed at around 85,000 miles. I had it replaced along with the timing belt to kill two birds with one stone.
my water pump failed which caused the timing belt to fail which bent every rod in the engine. $5000 estimate. It was a recall water pump installed in 2006. Contstantly inspect the pump and timing belt
I had a new timing belt and water pump done less than a year ago at the time there was apx 122k at the time. I had just cleared a 6 month very expensive set of hurdles to pass emissions and the last thing I would expect to go wrong was a water pump but sure enough that is the case and because of the pump failure it has started to shred timing belt and even caused the belt to start working its way of the pulleys. Thankfully it was noticed in time where it hasnt broken or slipped off completely.
I had the water pump and timing belt changed at 60,000 but just had a failure at 93,000 with internal engine damage. We are trying to determine what to do repair wise but its looking like a $5,000 repair and we are in shock.
I've had the entire coolant system worked on a few times now--there were fresh leaks every time something was fixed. After three visits to the mechanic, everything seems in working order now.
