i'm trying to change my belts in my 2000 Nissan Sentra GXE QG18de. i've loosened both the lock nut and tensioning bolt on the power steering pump pulley and the belt still wont loosen:balls:. the serpentine belt was super easy to loosen and remove from the idler pulley. not the same with the other belt. any tips or tricks? i see the pulley is slotted and am wondering if i need to remove the bolt behind the pulley on the tensioner plate.
