Hi there, here is an accessory drive belt diagram and instructions on how to replace the tensioner.

1. With the vehicle in Neutral, position it on a hoist.
2. Remove the 4 screws and position the RH fender splash shield aside.
3. Remove the 6 pin-type retainers and the RH splash shield.
4. Using the hex feature, rotate the accessory drive belt tensioner clockwise and remove the accessory drive belt from the coolant pump pulley.
5. Remove the 2 bolts and the accessory drive belt tensioner.
^ To install, tighten to 25 Nm (18 ft. lbs.).

Please let me know if you need further assistance.

After removing the belt, just remove the center bolt from from the pulley and replace. There is no torques spec for the bolt on the tensioner as it is recommended to replace it as a unit.
