(a) If reusing the timing belt, check the installation marks on the timing belt.
(1) Check that there are 3 installation marks on the timing belt by turning the crankshaft as shown in the illustration.
If the installation marks have disappeared, put a new installation mark on the timing belt before removing each part.
(b) Set the No. 1 cylinder to approximately 50° BTDC/compression.

(2) Check that the timing marks of the camshaft timing pulleys and timing belt plates are aligned.
If not, turn the crankshaft 1 complete revolution (360°).
imageOpen In New TabZoom/Print
(3) Using the crankshaft damper bolt, turn the crankshaft counterclockwise by approximately 50°.
NOTICE: If the timing belt is disengaged, having the crankshaft pulley at a wrong angle can cause the piston head and valve head to come into contact with each other when removing the camshaft timing pulley and camshaft, causing damage. So always set the crankshaft pulley at the correct angle.
