best way to determine which pulley is making noise or what newer belt newer altenator 01 DODGE RAM 5.2 1500
I use a PVC pipe or hard vacuum cleaner hose. With truck idling hold one end to your ear and carefully move the other end around the belt and pulleys. When you can hear the noise the best will mean you are close to the bad one. Use caution not to get it caught up in the belt.
