7. Timing Belt
A: INSPECTION
1. SOHC MODEL (INSPECTION OF TIMING
BELT POSITION)
1) Remove the timing belt cover (LH).
2) Rotate the crank pulley to set #1 cylinder piston
to top dead center of compression stroke and
check the followings.
(1) Confirm that the arrow (A) of camshaft pulley LH points in an upward direction.
(2) Remove the sealing rubber (B) of timing belt cover RH.
(3) Confirm that the arrow (C) of camshaft pulley RH points in an upward direction.
3) If the camshaft pulley or timing belt position is
not appropriate, check the faulty part and repair or
replace as required.
2. SOHC MODEL (OTHER INSPECTIONS)
1) Remove the front timing belt cover and timing
belt cover (LH).
2) While cranking engine at least four rotations,
check the timing belt back surface for cracks or
damage. Replace the faulty timing belt with new
part as needed.
3) When the side part of timing belt is abnormally
worn (fluff or jumping out of core) or damaged,
check the idlers, tensioner, water pump pulley and
cam sprocket to determine idler alignment (squareness). Replace the worn timing belt with new part.
4) Install the front timing belt cover and timing belt
cover (LH).
3. DOHC MODEL (INSPECTION OF TIMING
BELT POSITION)
1) Remove the timing belt cover (LH) and (RH).
2) Rotate the crank pulley to align single line mark
(A) on the intake camshaft pulley RH with notch (B)
on timing belt cover and check the followings.
(1) Confirm that the double line marks (C) on intake camshaft pulley RH and exhaust camshaft
pulley RH are aligned.
(2) Confirm that the single line mark (D) on exhaust camshaft pulley RH and notch (E) on timing belt cover are aligned.

(3) Confirm that the single line mark (A) on intake camshaft pulley LH and notch (B) on timing
belt cover are aligned.
(4) Confirm that the double line marks (C) on intake camshaft pulley LH and exhaust camshaft
pulley LH are aligned.
(5) Confirm that the single line mark (D) on exhaust camshaft pulley LH and notch (E) on timing belt cover are aligned.
3) If the camshaft pulley position is not appropriate,
check the faulty part and repair or replace as required.
4. DOHC MODEL (OTHER INSPECTIONS)
1) Remove the timing belt cover (LH).
2) While cranking engine at least four rotations,
check the timing belt back surface for cracks or
damage. Replace the faulty timing belt with new
part as needed.
3) When the side part of timing belt (arrow direction
shown in the figure) is abnormally worn (fluff or
jumping out of core) or damaged, check the idlers,
tensioner, water pump pulley and cam sprocket to
determine idler alignment (squareness). Replace
the worn timing belt with new part.
4) Install the timing belt cover (LH).
