Tried going over the alt pulley and tried to push the belt under the idler pulley to no avail.

Now the truck is sitting in a parking lot until tomorrow. There is very little on this topic on the web. I found this thread and thought maybe I could get some help. Is this only a problem when you have a non-OEM tensioner? All the belts listed seem to show 88.25". It makes sense that a longer belt would fit, but why so few posts about it? I would think that if it was widespread, we could find more info about it. The shop that replaced my tensioner last year got this belt on. They had to have pried it on.

Any thoughts? thanks!
