The position of the indicator when aligning the camshaft belt tensioner at different temperatures is shown in the illustration.
Turn the crankshaft clockwise carefully until the camshaft belt is tensioned.
The belt must be tight between the intake cam, the idler pulley and the crankshaft.
Hold the belt tensioner center screw secure and turn the belt tensioner eccentric counter-clockwise until the tensioner indicator passes the marked
position.
Then turn the eccentric back so that the indicator reaches the marked position in the center of the window.
Secure the eccentric and tighten the center screw to 20 Nm (15 lb.ft) .
Check that the indicator is in the correct position.
A new alignment must be carried out if the indicator is not in the correct position.
