- 1). Open the hood. Locate the serpentine belt tensioner on the passenger side of the front of the engine.
- 2). Place the square end of a ½-inch drive ratchet wrench into the hole on the front of the tensioner.
- 3). Rotate the handle of the wrench in a counter-clockwise direction until the belt tension releases. Continue to hold the wrench handle in this position.
- 4). Slide the serpentine belt off of the nearest accessory pulley within your reach while holding the wrench handle to keep the tension released.
