The 2012 Dodge Grand Caravan 3.6L engine uses a serpentine belt to drive multiple accessories. This single belt replaces the need for multiple V-belts, improving efficiency and simplifying maintenance. Understanding the belt routing is crucial for proper installation and replacement.

Serpentine Belt Routing

The serpentine belt in the 2012 Dodge Grand Caravan 3.6L engine follows a specific path around various pulleys. Here's the routing order:

It's important to note that the smooth side of the belt contacts the idler pulley and tensioner pulley, while the ribbed side engages all other components.

Belt Tensioner

The belt tensioner is a crucial component in the serpentine belt system. It maintains proper tension on the belt, ensuring optimal performance and longevity. To release tension when replacing the belt:

  • Locate the tensioner pulley
  • Use a 3/8-inch drive ratchet or breaker bar
