Accessory drive belt - vehicles with supercharger

Removal

Open the engine compartment and fit paint work protection sheets.
Remove the supercharger drive belt, for access. See: Drive Belt, Supercharger
Check the belt wear indicator marks to confirm that the drive belt is/is not within limits.

CAUTION: When releasing the belt tension, never apply any torque in a clockwise direction to the pulley center bolt (left hand thread) as it could subsequently loosen. Remove the drive belt from the accessory drive. Use a spanner e.g. Churchill JD-230 or Snap On XDHM 1415, on the center bolt of the belt tensioner idler pulley, to turn the adjuster assembly to the left, viewed from the front, against spring tension. Whilst holding the tensioner against spring tension, remove the drive belt from the generator pulley. Release the tensioner slowly and remove the spanner. Disconnect the belt from the other pulleys, as necessary.
