Remove the cylinder head cover.
. Refer to page 6 46 when installing.
Remove the upper cover (see page 6 19).
Inspect the timing belt for cracks and oil or coolantsoakrng.
NOTE:
. Replace the belt if oil or coolant soaKeo.. Remove any oil or solvent that gets on the belt.
Rotate pulleyand inspect belt.
After inspecting, retorque the crankshaft pullev bolt{see page 6- 16).

Tension Adjustment
CAUTION: lt*ays aa;j"t the timing bett rension withthe engine cold.
NOTE:
. The tensioner is spring loaded to apply tension to thebelt automatically after making the following adjustment.
. Always rotate the crankshaft counterclockwise whenviewed from the pulley side. Rotating it clockwisemay result in improper adjustment of the belt ten-sion.
. lnspect the timing belt before adjusting the belt ten-ston.
1.Remove the cylinder head cover.
. Refer to page 6,46 when installing.
Remove the upper cover (see page 6,'19).
Rotate the crankshaft five or six revolutions to setthe belt.
Set the No. 'l piston at TDC (see page 6-21).
Loosen the adjusting bolt 180'.

Removal
NOTE:
. Replace the timing belt at 105,000 miles (168.000 km)
according to the maintenance schedule (normal con-
ditions/severe conditions).
lf the vehicle is regularly driven in one or more of the
followlng conditions, replace the timing belt at 60.000
miles (U.S.A.) 100,000 km {Canada).
.In very high temperatures (over 110'F.43'C)
. In very low temperatures (under -20'F, -29"C)'
! Turn the crankshaft pulley so the No. 1 piston is at
top dead center (TDC) before removing the belt (see
page 6'21).
. Inspect the water pump before installing the timing
belt {see Page 10-14).
1. Remove the splash shield (see page 5-7).
2. Loosen the mounting bolt and lock bolt. then remove
the power steering (P/S) pump belt and pump
