The crankshaft pulley and torsional vibration damper assembly is attached to and rotates with the crankshaft. The pulley provides the drive for the accessory drive belts which in turn provides rotational power for the front mounted accessory components such as the generator, the A/C compressor, the coolant pump, power steering pump (AWD only) and the supercharger. The belt tensioner on each belt maintains the correct tension of the drive belt.
