Thanks, to confirm you mean the remove the 4 bolts hold the pump to the frame and slide the pump toward rear of MH, opening a gap near the coupler?
Both belts look real good from a wear perspective, except that debris seems to gotten in between the belt and a pull and have damaged some of the ‘v’s in the serpentine so since I had it apart to do the timing cover gasket/seal. I thought now that I know about it I could not put it back together with that belt. Even tho it might run 30k more miles , there is the chance it won’t.
Thank you for the #s was going to looking for those also.
Appreciative

Unbolt the pump from the mounting bracket and slide it straight back towards the rear bumper this should give you enough room to change the belt.
While your there check the pump coupler insert for ware and also for ware or corrosion of the couplers metal parts they tend to rt away
It is also very important to correctly align the coupler when reinstalling the pump
And you might want to do the water pump belt at the same time while you are in there
Serpentine belt # NAPA 25-080700
Water pump belt #CAT 036-6775
Coupler insert #MAGNALOY M570H5
Coupler engine side # MAGNALOY M500-301-20042
Coupler pump side # MAGNALOY M500-810008SRC
Hope this helps
