The accessory drive is a belt system powered by a pulley attached to the front of the crankshaft. The crankshaft pulley, which incorporates a torsional vibration damper, transmits power to the drive belt. A belt tensioner is incorporated into the belt run to maintain the correct tension of the drive belt. Together with idler pulleys, the belt tensioner also guide the drive belt clear of obstructions and sets the correct 'wraparound' of the accessory component drive pulleys to ensure a slip-free drive.

The drive belt is a six-ribbed poly-V belt that drives the:

Coolant pump
Air Conditioning (A/C) compressor
Generator

The belt tensioner consists of an idler pulley on the end of a spring loaded pivot arm. The pivot arm can be turned manually for removal and installation of the drive belt. The belt tensioner is calibrated to automatically maintain the correct tension in the drive belt.
