Choosing a replacement belt is not simply a matter of finding another belt labeled 4PK. For a successful 4PK serpentine belt replacement, the new belt needs to match the original belt and the vehicle's accessory drive system in several important ways, including rib count, effective length, profile, routing, and application.

When comparing 4PK vs 5PK vs 6PK belts, the first difference is easy to see: the number of ribs. But rib count is only the starting point. The belt must also correspond to the pulley configuration, belt profile, length, and the accessory drive system for which it was designed.
