INSTALLATION
(1) Set the crankshaft sprocket to TDC by aligning the
sprocket with the arrow on the oil pump housing.
(2) Set the camshafts timing marks together by alig ning
notches on sprockets.
(3) Move the crankshaft to notch before TDC.
(4) Install the timing belt. Starting at the crankshaft, go around
the water pump sprocket, idler pulley, sprockets
and then around the tensioner pulley.
(5) Move the crankshaft sprocket to to take belt
slack.Install the tensioner to block ‘but do not tighten
fasteners.
(6) Using a torque wrench on the tensioner pulley, apply
28 Nm (21
of torque to tensioner..
(7) With torque being applied to the tensioner pull ey, move
the tensioner up against the tensioner pulley brack et and
tighten fasteners to 31 Nm (23
(8) Pull the tensioner plunger pin. Pretension is correct when
the pin can be removed and installed.
(9) Rotate the crankshaft 2 revolutions and check t he
alignment of the timing marks. If marks are not ali gned
correctly, do it again.

INSTALLATION
Align the notches on the stopper with the engine mo unt bracket
with the arrow mark facing toward the shown direction. Then
