3. Line up the timing marks of the right bank camshaft
sprockets.
4. Line up the timing marks of the crankshaft sprockets.
5. Install the timing belt on each sprocket in the following
sequence.
(1) Install the timing belt on the crankshaft sprocket and then
on the idler pulley, while tightening it to prevent
slackness.
(2) Line up the timing marks of the left bank camshaft
sprockets.
(3) Install the timing belt on the water pump pulley, while
taking up the slack.
(4) Install the timing belt on the right bank camshaft sprocket.
(5) Install the timing belt on the tensioner pulley.
6. Lightly press the tensioner pulley against the belt and
temporarily tighten the center bolt.
7. Check to see that the timing marks of all the sprockets are in
a alignment.
8. Using special tool MD998769, rotate the crankshaft a

13.Check to see whether the metal wire inserted when the
auto-tensioner was installed can be removed without any
resistance.
If the metal wire can be removed without any resistance, it
means that the belt has a proper tension. Therefore, remove
the metal wire. In this condition, check that the projection of
the rod of the auto-tensioner is within the standard value.
Standard value: 4.8
− 5.5 mm (0.19 − 0.21 inch)
14.If the metal wire offers resistance when removed, repeat the
previous steps (9) through (12) until a proper belt tension is
obtained.

TENSIONER PULLEY AND IDLER PULLEY
Turn the pulley. If it does not rotate smoothly, or develops noise
or excessive play, replace the pulley.
.
AUTO-TENSIONER
1. Check for oil leaks. If oil leaks are evident, replace the auto-
tensioner.
2. Check the rod end for wear or damage and replace the auto-
tensioner if necessary.
3. Measure the rod protrusion. If it is out of specification,
replace the auto-tensioner.
Standard value: 12 mm (0.5 inch)
4. Press the rod with a force of 98 to 196 N (22 to 44 pounds)
and measure the movement of the rod.
If the measured value is out of the standard value, replace
the auto-tensioner.
Standard value: 1.0 mm (0.03 inch) or less
