Looking for info or video on changing the serpentine belt on my 2007 Coachmen Cross Country 389DS. It has the 300hp Cummins engine. I’ve looked on YouTube and haven’t had any luck.Any help is greatly appreciated.

You have to take the tension off of the belt by turning the tensioning pulley. You do that with a 1/2" drive rachet. The 1/2" "hole" is in the middle of the tension pulley. Once you have the tension off, you have to remove the belt and install the new one. Take a picture of the old belt in place.
