Notes on adjusting the automatic timing belt tensioner (Chevrolet Aveo T250)

After installing the timing belt, rotate the coolant pump clockwise until the tensioner pointer aligns with the mark on the tensioner mounting bracket.



Tighten the coolant pump mounting screws and turn the crankshaft two revolutions. Loosen the coolant pump mounting screws and repeat the automatic tensioner adjustment procedure. Tighten the coolant pump mounting screws to 10 Nm.
