Volkswagen Golf/Jetta/Cabriole 1990-1999

Timing Belt

Print


NOTE
There is no recommended timing belt service interval from the manufacturer. We recommended that the belt be inspected every 30,000 miles and replaced at every 60,000 mile interval. If the belt stretches there is a chance that it may jump a tooth throwing the timing off. If this occurs one or more of the pistons could contact the valves causing extensive damage.

If the vehicle has been stored for long periods (2 years or more), the belt should be changed before returning the vehicle to service.

REMOVAL & INSTALLATION




NOTE
Do not turn the engine or camshaft with the timing belt removed. The pistons will contact the valves and cause internal engine damage.

  1. Disconnect the negative battery cable and remove the accessory drive belts, crankshaft pulley and the timing belt cover(s).
  2.  
  3. Temporarily reinstall the crankshaft pulley bolt and turn the crankshaft to TDC of No. 1 piston. The mark on the camshaft sprocket should be aligned with the mark on the inner timing belt cover or the edge of the cylinder head.
  4.  
  5. With the distributor cap removed, the rotor should be pointing toward the No. 1 mark on the rim of the distributor housing. On 8 valve engines, the notch on the crankshaft pulley should align with the dot on the intermediate shaft sprocket.
  6.  
  7. Loosen the locknut on the tensioner pulley and turn the tensioner counterclockwise to relieve the tension on the timing belt.
  8.  
  9. Slide the timing belt from the sprockets.
  10.  

To install:

  1. Check the alignment of the timing marks. On 16 valve engines, the mark on the tooth should align with the mark on the rear belt cover.
  2.  
  3. Install the new timing belt and tension the belt so it can be twisted 90 ° at the middle of it's longest section, between the camshaft and intermediate sprockets.
  4.  
  5. Recheck the alignment of the timing marks and, if correct, turn the engine 2 full revolutions to return to TDC of No. 1 piston. Recheck belt tension and timing marks. Readjust as required. Torque the tensioner nut to 33 ft. lbs. (45 Nm).
  6.  
  7. Install the belt cover and accessory drive belts.
  8.  
  9. If the belt is too tight, there will be a growling noise that rises and falls with engine speed.

Diesel Engines

Some special tools are required. A flat bar, VW tool no. 2065A, is used to secure the camshaft in position. A pin, VW tool no. 2064, is used to fix the pump position while the timing belt is removed. The camshaft and pump work against spring pressure and will move out of position when the timing belt is removed. It is not difficult to find substitutes but do not remove the timing belt without these tools.


NOTE
Do not turn the engine or camshaft with the timing belt removed. The pistons will contact the valves and cause internal engine damage.

  1. Disconnect the negative battery cable and remove the accessory drive belts, crankshaft pulley and the timing belt cover(s). Remove the camshaft cover and rubber plug at the back end of the camshaft.
  2.  
  3. Temporarily reinstall the crankshaft pulley bolt and turn the crankshaft to TDC of No. 1 piston. The mark on the camshaft sprocket should be aligned with the mark on the inner timing belt cover or the edge of the cylinder head.
  4.  
  5. With the engine at TDC, insert the bar into the slot at the back of the camshaft. The bar rests on the cylinder head to will hold the camshaft in position.
  6.  
  7. Insert the pin into the injection pump drive sprocket to hold the pump in position.
  8.  
  9. Loosen the locknut on the tensioner pulley and turn the tensioner counterclockwise to relieve the tension on the timing belt. Slide the timing belt from the sprockets.
  10.  

To install:

  1. Install the new timing belt and adjust the tension so the belt can be twisted 45 degrees at a point between the camshaft and pump sprockets. Torque the tensioner nut to 33 ft. (45 Nm).
  2.  
  3. Remove the holding tools.
  4.  
  5. Turn the engine 2 full revolutions to return to TDC of No. 1 piston. Recheck belt tension and timing mark alignment, readjust as required.
  6.  
  7. Install the belt cover and accessory drive belts.
  8.  
  9. If the belt is too tight, there will be a growling noise that rises and falls with engine speed.
