Good information thanks!

I know Goodyear makes the belt and an after market tensioner. Both have worked good for me. And the $$ is right. If you really have a problem with the auto tensioner, Granger's makes a manual bolt adjustment 1 that cost about $350. I'd have to search it again but know it exists.

I only use a quick squirt to determine which belt is making the noise and if it's the belt or the tension at fault. A good belt with poor tension will keep squealing but a bad belt with good tension will tend to go silent for a moment.

It's not a science, just a trick that works for me 99% of the time.

You can go here and get the proper part number from dayco. You can cross that number to other manufacturers. I don’t know if you buy online. I used eBay and got the fan tensioner for 90 dollars that way. It was a genuine dayco. Good luck.

Does anyone know if the cm870 and cm871 share the same drive and accessory belt? if yes i have the part number already for the accessory belt from a 871 i would just want to know the drive belt part number now. I use the cummins online store to ask for the cm870 belt for the truck but they said i have to get that info from truck manufacturer. thanks
