After installing the belt, you need to adjust its tension.
Adjusting belt tension
Loosen the tightening of the nut 1 securing the bracket 3 of the tension roller and the adjusting bolt
Rotate bracket 3 with roller 4 away from the engine block, thereby tensioning the belt.
Tighten bolt 2 and check the belt tension as indicated above.
If the belt tension is normal, tighten nut 1.
