Tighten the screws. Tighten to 17 Nm .
Installing the timing belt
Install the new belt in the following order:
*the idler pulley
Tension the timing belt
NOTE: This adjustment is to be made with a cold engine. Suitable temperature is approximately 20 degree C/67 degree F .
At higher temperatures (with the engine at operating temperature or a high outside temperature for example) the indicator is further to the right.
The above figure shows the position of the indicator at different engine temperatures.
*Carefully turn the crankshaft clockwise until the timing 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. 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
*Hold the eccentric securely. Tighten the center screw. Tighten to 20 Nm .
Check that the indicator is in the correct position.
*Press the belt to check that the indicator on the tensioner moves easily
*Install the upper timing cover
