How do i change serpentine belt ply voy - Voyager Plymouth Cars & Trucks

There are two pulleys that have no ribs on most Voyager engines from at least 91 thru 2003. One, the idler pulley is stationary. The other, The tensioner pulley is mounted to a spring loaded arm and in intended to keep the belt properly tightened. The tensioner pulley is attached to its arm with a 15 mm bolt. The tensioner assembly is rotated toward the front of the vehicle by putting a 15 mm box end wrench on that bolt and turning it clockwise as if you were trying to tighten the bolt. The belt will loosen which will allow the belt to be removed. There is, or should be a belt routing guide mounted under the hood. Use that guide to install the new belt. Here's the trick. With the belt installed on all of the pulleys except the tensioner, position the belt against the pulley as if to slide it on, THEN put the wrench on its bolt, pull forward until the belt slip over the pulley and then let the tensioner rotate counter clockwise until the belt is tight. BE CAREFUL: the grooves in the belt must be in the correct grooves in the pulleys that have grooves. Check them twice from the top and the bottom. Good luck!
