- 1). Park the Honda CR-V in a safe working area. Raise the hood.
- 2). Locate the automatic tensioner below the alternator. The automatic tensioner has a pulley on one end that the serpentine belt is traveling under. There is a bolt head in the center of the pulley.
- 3). Turn the pulley counter clockwise with the 1/2-inch drive breaker bar and a socket to loosen the tension from the belt. Then, slide the belt off the automatic tensioner pulley.
- 4). Continue to turn the bolt head in the center of the automatic tensioner pulley counter clockwise until the bolt loosens. Then, release the automatic tensioner and finish unscrewing the bolt with your fingers.
- 5). Pull the pulley off the automatic tensioner and push the new pulley in place. Screw the bolt back into the center of the pulley and tighten the bolt down tight with the breaker bar and socket. Once the bolt is very tight, turn the pulley counterclockwise again.
- 6). Slide the serpentine belt back under the pulley and release the pulley. Remove the breaker bar and socket from the pulley.
- 7). Crank the Honda CR-V and watch the serpentine belt as it travels under the pulley just to ensure that the belt is going to stay centered under the pulley. Turn the engine off and close the hood.
