5. Install the timing belt.
a. Align each camshaft and crankshaft pulley
mate mark to the respective indicator as indi-
cated in the figure.
b. Install the timing belt with its direction of rota-
tion mark put at the time of the removal facing
toward the same direction as before.
c. Make sure that all of the mate marks put at the
time of the removal and the pulley marks are
aligned with each other.
6. Install the timing belt tensioner subassembly. To
adjust the tension of the timing belt:
a. Remove the resin cap attached to the oil pump
body.
b. Temporarily install the timing belt tensioner
(only to the extent that it can swing slightly.)
c. Screw an M6 screw (pitch: 1 mm, length: 20-
30 mm) fully into place from which the resin
cap was removed, using your thumb and index
finger. At this time, make sure to insert a steel
plate between the screw and the tensioner so
that no damage may be made to the roller
section of the tensioner.
d. Tighten the tensioner to the specified torque.
Tightening Torque: 23.1 - 34.7 ft-Ib
(3.2 - 4.8 kg-m)
