This adjustment is to be made with a cold engine.

A suitable temperature is approximately 20°C/68°F.

At a higher temperature, for example with a warm engine or a higher ambient temperature, the needle is further to the right.

The illustration above shows the indicator position when adjusting the belt tensioner at different engine temperatures.

Tighten the timing belt as follows:

Carefully turn the crankshaft clockwise until the camshaft belt is tensioned.
The belt must be tensioned between the intake camshaft pulley, 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 needle reaches the marked position corresponding to the relevant temperature.
At 20°C (68 °F) the needle must be centered in the window.

See the illustration above.
Hold the eccentric secure 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.
