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 warmer ambient temperature, the needle is further to the right. The illustration above shows the position of the indicator when
aligning the timing belt tensioner at approximately 20°C/68°F.
Note: There are two different tensioners depending on model year.
-
Fix the belt tensioner center screw in position and turn the belt tensioner eccentric clockwise until the tensioner indicator passes the marked
position and reaches the end position. Then turn the eccentric back so the indicator reaches the marked position illustrated. Tighten the center
screw.
-
Check that the indicator is in the correct position.
Tightening
-
Slacken off the 3 screws for the timing gear pulley slightly (applies to both timing gear pulleys). Install the center plug in the variable valve timing
unit. Hold the center plug at 25Nm at the same time as tightening the 3 screws on the camshaft timing gear pulley. Tighten the 3 screws on the
timing gear pulley for the intake camshaft. This is to ensure that the variable valve timing (VVT) unit is in its end position when the timing gear
pulley is tightened.
