I had a tensioner go out on me and ordered the gates tensioner part number (38285). This is on a 05 5.9L. I do not know the brand of the old tensioner. It has GAT45, GAT52, 376BI, and made in Korea on it. The gates tensioner is about 3/8” shorter from center of the bolt hole to the edge of the pulley. Subsequently my belt is now 3/8” short off being able to go back on. I tried until I started throwing tools. I have checked 100 time to make sure the belt is seated properly. Does anyone have any idea what might be wrong befor I send the part back. I have read reviews of a lot of people who said it fit there third gen.
