Installation of a toothed belt (VW Golf 3)

When tensioning the engine belt, a special key for adjusting the belt tensioner, as well as a tension measuring tool, must be available.

When installing a new timing belt, the timing marks must be aligned. When tensioning the timing belt, proceed as follows.



Insert the trunnion wrench into both holes of the tension roller as shown and turn the roller in the direction of the arrow to tension the belt.

Place the VW210 tension gauge on the timing belt and push the gauge handle inward. The belt is optimally tensioned if the gauge readings are between 13 and 14. Otherwise, readjust the tension roller.

Turn the crankshaft twice and check the tension.

Install the upper timing belt protector, vibration damper and V-belt. Adjust the belt tension 15.

If the crankshaft flywheel has been removed, install it on the crankshaft. There is a groove on the end of the crankshaft, and a guide lug on the inside of the gear hole. Make sure they match perfectly. Lubricate the screw threads with oil and tighten the screw to a torque of 90 Nm. From the end position of the screw, tighten it another half turn, without using a torque wrench. The engine must be locked from turning.
