Audi S6 – Timing Belt Service w/ Water Pump

The Audi S6 timing belt service does not normally require removal of the nose of the car, but in this case the silicone filled fan clutch was seized onto the idler shaft and could not be removed with the nose in place. 10 years and more recently time in the coastal environment seemed to have done its worse. To fully access the clutch required removal of the front bumper cover, radiator support and radiator, evacuate and recharge of the A/C system. As the engine water pump is driven off the camshaft belt, it is a good idea to replace the pump at the same time as belt service. All tensioner rollers should be inspected or replaced at the time of belt service.
