Toothed belt tension adjustment
Weakening
1. Remove upper toothed belt cover.
2. Install a nut tool, for example HA2ET 2587, on the tension roller.
3. Loosen the screw securing the tension roller with a spanner wrench.
4. Turn the tension roller to the left, in the direction opposite to the arrow (see fig. Toothed belt tension adjustment) and loosen the toothed belt.
Tension
1. Turn the tension roller to the right, in the direction of the arrow (see fig. Toothed belt tension adjustment) and tension the toothed belt.
2. The toothed belt, when exposed to it with thumb and forefinger in the middle between the camshaft drive gear and the idler gear, can be twisted by 90°.
3. Tighten the tensioner roller nut to 45 Nm.
4. Install the upper toothed belt cover.
5. Let the engine run. If the belt whistles, the tension is usually too high.
