NOTICE:
Check the drive belt deflection at the specified point.
When installing a new belt, set its tension value as
specified.
When inspecting a belt which is used for over 5 min-
utes, apply the specification of ºUsed beltº.
When reinstalling a belt which is used for over 5 min-
utes, adjust its belt deflection and tension to the inter-
mediate value of each specification in ºUsed beltº.
The V- ribbed belt tension and deflection value
should be checked after 2 revolutions of engine
cranking.
When using a belt tension gauge, confirm the accura-
cy first by using a master gauge.
7. INSPECT IGNITION TIMING
(a) Warm up engine.
(b) When using the hand-held tester or OBD II scan tool:
(1) Connect the hand-held tester or OBD II scan tool
to the DLC3.
(2) Enter DATA LIST MODE on the hand-held tester or
OBD II scan tool.
Ignition timing: 8 to 12 BTDC
HINT:
Refer to the hand-held tester or OBD II scan tool operator's
manual if you need help to select DATA LIST.

18. REMOVE TIMING BELT
(a) Set the No. 1 cylinder to the TDC/compression.
(1) Temporarily install the crankshaft pulley bolt and
washer to the crankshaft.
(2) Turn the crankshaft clockwise, then align the timing
mark of the crankshaft timing pulley with the oil
pump body.
(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.

53. 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.
