Execution sequence
1. Remove the front timing belt cover (see «Timing belt for 1.6i engine - checking the condition and adjusting the tension»).
Recommendation. When replacing the tensioner pulley without removing the toothed belt, there is a risk of the belt jumping over the pulley teeth, which will lead to a shift in the valve timing. Therefore, before loosening the belt tension, align the mark on the camshaft pulley with the protrusion of the rear belt cover (see «1.6i engine timing belt - replacement»). After installing the roller, the label should not move.
2. Loosen the tightening nut of the tension roller (see «1.6i engine timing belt - checking condition and adjusting tension») and turn it off completely.
3. Remove the roller from the stud, keeping the belt taut.
4. We install a new roller on the stud and fix it with a nut and washer, preventing the belt tension from loosening.
5. Adjust the tension of the timing belt (see «1.6i engine timing belt - checking condition and adjusting tension»).
6. Install the front timing belt cover.
