2012 Sierra RCSB 5.3 build thread @ New Era Performance
#314
I figured I would update my thread here with some information. About a month ago, when I was doing some street tuning with my truck, on a violent 2-1 downshift, it ripped my water pump pulley right off. Since then, we replaced the water pump, and tack welded the pulley to the shaft in 3 places and it was all good until this past Sunday night. I was out playing around on the highways with some friends and on my way home, it ripped the tack welded water pump pulley off as well. We are going to now replace the water pump again, and this time weld it around the shaft and pulley entirely.
