(3) Check that the timing marks of the camshaft timing
pulleys and the timing belt No. 3 cover are aligned.
If not, turn the crankshaft by 1 revolution (360).
(4) Remove the crankshaft pulley bolt.
(b) If reusing the timing belt, check that there are 3 installa-
tion marks on the timing belt as shown in the illustration.
(1) If the installation marks have disappeared, put new
installation marks on the timing belt before remov-
ing.
(c) Set the No. 1 cylinder to approximately 60 BTDC/com-
pression.
(1) Turn the crankshaft counterclockwise by approxi-
mately 60.
NOTICE:
If the timing belt is disengaged, having the crankshaft
pulley set at the wrong angle can cause contact of the pis-
ton head with the valve head when removing the camshaft
timing pulley and camshaft, which causes damage. So al-
ways set the crankshaft pulley at the correct angle.
(d) Remove the timing belt tensioner.
NOTICE:
Do not reinstall the tensioner with its plunger extended.
(e) Remove the timing belt in this order.

14. INSPECT TIMING BELT
NOTICE:
Do not bend, twist or turn the timing belt inside out.
Do not allow contact of the timing belt with oil, water
or steam.
Do not use the timing belt tension when installing or
removing the mounting bolt of the camshaft timing
pulley.
Check the belt for any defects as shown in the illustrations.
Also, check these points below.
(a) If the belt tears in a short time:
Check if the belt is installed properly.
Check if the timing cover gasket is damaged and if
it is installed properly.
(b) If the belt teeth are cracked or damaged, check if either
camshaft is locked.
(c) If there is noticeable wear or cracks on the belt face,
check if there are nicks on the side of the idler pulley lock
and water pump.
(d) If there is wear or damage on only one side of the belt,
check the belt guide and alignment of each pulley.
(e) If there is noticeable wear on the belt teeth:
Check the timing cover for damage.
Check that the gasket has been installed correctly.
Check for foreign objects on the pulley teeth.
If there is any doubt about the belt condition, replace the timing
belt.
15. INSTALL TIMING BELT
(a) Remove any oil or water on the pulleys, then keep them
clean.
NOTICE:
If there is a trace of water and/or oil on the timing belt,
repair the leakage and install a new timing belt.
Only wipe the pulleys; do not use any cleaning agent.
(b) Check the idler pulleys.
(1) Check that the idler pulley turns smoothly.
(2) Visually check the seal portion of the idler pulley for
oil leakage.
(c) Check the water pump.
(1) Turn the pulley, then check that water pump bearing
moves smoothly and does not make a noise.
(2) Visually check the drain hole for coolant leakage.
(d) Temporarily install the crankshaft pulley bolt and washer
to the crankshaft.
