The engine crankshaft pulley
drives the accessory components, which comprise the torsional vibration damper,
generator, power steering pump, A/C compressor and coolant pump, via the
accessory drive belt.
The belt, which is maintenance free poly-V type
belts, are automatically pre-loaded by the tensioning rollers and are routed
over deflection pulleys in order to maintain sufficient adhesion about the drive
wheels. This ensures slip-free drive of the accessory components.
