Replaced the factory original water pump on this Cutlass LS Ciera car in 2013 with a NAPA lifetime warranty unit.
Drove car about 10,000 miles with the replacement water pump. I was driving this car last week not far from home, and all of a sudden water temp went hot really fast and I got the red engine temp light on the instrument panel, got the car stopped very shortly after and opened up hood to investigate but found nothing to indicate any issues.
I was real close to a local shop so they did a coolant system pressure check and found that the water pump had in fact failed to the point that all the coolant was quickly running out of the pump. Up to this point, there was no indication of loss of coolant or unusual water temps. I am suspecting that besides the water pump sudden failure, there was a problem with the water temp sensing gauge or system as I should have had a better warning of engine getting hot in much sooner time frame. Now, it looks like the engine got so hot that the head gaskets warped and coolant fluid leaked past the head gaskets into the engine oil.
