I heard grinding noises coming from the water pump and replaced it twice now and about a week after each replacement the grinding noise returned. The first pump was a new after market and the second pump was a rebuilt OEM. Is there something else wrong or am I installing the pump incorrectly, (i.e. incorrect orientation on the bolt pattern? I did notice an arrow marking on the edge of the pump which I installed on top.

Remove the serp belt, rotate all pulleys, they should spin freely, all except the crank! Pay particular attention to the a/c pulley, and did you replace the belt and tensioner?
