Align the mark (can be a dot or notch) on the intermediate shaft sprocket with the notch in the crank pulley. Align the mark (can be a dot or notch) on the "Back" of camshaft sprocket with the top edge of the valve cover gasket. Be sure all the timing marks are properly aligned.
For further information refer to Timing Belt : Service and Repair
NOTE :
The 8 valve engine requires a special wrench, Volkswagen No. US4493 or equivalent, to adjust the camshaft drive belt tensioner. Whenever the drive belt is removed and refitted, the camshaft and intermediate shaft timing MUST be adjusted. The drive belt can be replaced without removing the belt sprockets.
NOTE :
On high mileage engines, failure of the tensioner bearing is a possibility. Consider replacing the bearing when replacing the timing belt.
NOTE:
Very slight movement of sprockets and marks can be expected as belt tension is adjusted. Slight movement is OK. The smallest possible increment of adjustment is one whole tooth of the belt or sprocket.
