Belt tensioner - Diesel Forum

Im getting a funny high pitched noise that changes with RPM, Ive got 152k miles so I want to start with changing the belt tensioner. Anybody have the part number? Should I go with OEM or is there something better out there?

mine just self-destructed. got the replacement at Advance - their part # 89257, made in USA by Dayco. did the job.

Mine exploded this summer. I used whatever one my wife picked up at NAPA and brought out to me on the highway. It is working fine.

Mine was making noise before it broke into three pieces. I just waited too long to figure out if it was the idler pulley or the tensioner.

The idler pulley is a lot cheaper to replace.

Personally, I replaced the tensioner and all the idlers. Leaves me with spares if I were to get stranded on the side of the road. That's the most reliable route.

I replaced the bearing in my idler when it got bad. Simple job and about $4.
