Review on ACDelco 12609719 Original Equipment Tensioner: Ensuring Optimum Performance by Derek Faseworld

This was the only pulley I had an issue with when I replaced all my pulleys and belts. The problem is actually ACdelco's fault. If you put in your VIN they can give you this part as a spare. and reason. They don't make one identical to my original part, but this one will do. I decided to use my original which has three screw points. One day I will replace it with a similar one from a competitor that perfectly matches my original. My concern is that it might rip your ears off the water pump where this thing bolts on. I didn't want to find out. So take a look inside your engine and see what you've got. If it's two screw points without a triangular bracket, then it's one. I am attaching a photo of my water pump. The two screws on the ears on the left are where this connects. The third screw sits firmly in the stable housing above the water pump bracket.
