Attention: This procedure is described only for the petrol engine.
4 cylinder engine
Weakening
Remove the top toothed belt cover.
Fit HAZET 2587 or a suitable wrench onto the tensioner.
Loosen the fixing nut of the tension roller with a spanner wrench.
Turn the pulley to the left and loosen the toothed belt.
Caution: If the toothed belt has been removed or moved, the timing must be reset.
Tension
Turn tensioning pulley to the right in the direction of the arrow and tension the toothed belt.
The tension should be such that the toothed belt in the middle between the gears of the camshaft and intermediate shaft can be turned by 90°with the index and thumb.
Tighten the lock nut on the tension roller to 45 Nm.
Engine 115 HP s., letter designation AAD
This engine is equipped with a thermal tension roller. This roller automatically compensates for changes in the length of the toothed belt due to temperature, but the toothed belt must be tightened as part of maintenance.
Weakening
Loosen the toothed belt on a 4-cylinder engine without a thermal roller. To do this, loosen the bolt -1 -
Tension
The engine must be at room temperature.
Turn the nut holder in the direction of the arrow and tension the toothed belt.
With the correct tension, the toothed belt in the middle between the gears of the camshaft and intermediate shaft can be turned by 90°with the index finger and thumb.
Tighten bolt -1 - to 20 Nm
Install top timing belt cover
Start the engine. If the toothed belt whistles, then it is too tight.
5 cylinder engine
Weakening
Remove toothed belt cover.
Loosen the 3 cooling water pump mounting bolts, turn the pump to the right and loosen the toothed belt.
Tension
Turn the water pump to the left with the pry bar (up) and tension the toothed belt.
With the correct tension, the toothed belt in the middle between the camshaft gear and the water pump can be rotated 90°with the index finger and thumb (¼ turn).
Tighten the cooling water pump mounting bolts
Recheck toothed belt tension
Install the toothed belt cover.
Start the engine. A whistling toothed belt indicates its excessive tension.
