Stay away from the new Cardone 8-bolt water pumps. Too great of clearances in their manufacturing process allows the shaft to creep backwards, and then the seal lets go. I went through 3 new water pumps, and the last pump I returned, they admitted that all of the new pumps eventually fail with the same problem. This was only three weeks ago, and I bet it will take a long time before the bad stock is gone. Don't know if they are having problems with the 11-bolt ones or not.
