Installation Note
Tensioner and tensioner spring
1. Install the tensioner and the tensioner spring.
Caution
l Protect the tensioner with a rag before prying on it.
2. Using a suitable bar, pry the tensioner outward (arrow).
3. Temporarily tighten the tensioner lock bolt with the tensioner
spring fully extended.
Timing belt
1. Verify that the timing belt pulley mark is aligned with the tim-
ing mark.
2. Verify that the camshaft pulley marks are aligned with the
seal plate marks.
3. Install the timing belt so that there is no looseness at the
idler side or between the camshaft pulleys.
4. Install the pulley boss and pulley lock bolt.
Caution
. Do not turn the crankshaft counterclockwise.
5. Turn the crankshaft two turns clockwise and face the pin
on the pulley boss upright.
6. Verify that the camshaft pulley marks are again aligned with
the seal plate marks.
If not aligned, remove the timing belt and repeat from ten-
sioner installation.
7. Turn the crankshaft 1 and 5/6 turns clockwise and align the
timing belt pulley mark with the tension set mark for proper
timing belt tension adjustment.
8. Using the
SST (49 DO1 1 102), loosen the pulley lock bolt
and remove the bolt and pulley boss.
Caution
l Do not turn the crankshaft. . .
9. Verify that the timing belt pulley mark is aligned with the ten-
sion set mark.

Timing Belt
1. Verify that the timing belt pulley mark is aligned with the tim-
ing mark.
2. Verify that the camshaft pulley marks are aligned with the
seal plate marks.
3. Install the timing belt so that there is no looseness at the
idler side or between the camshaft pulleys.
4. Install the pulley boss and pulley lock bolt.
Caution
l Do not turn the crankshaft counterclockwise.
5. Turn the crankshaft two turns clockwise and face the pin
on the pulley boss upright.
6. Verify that the camshaft pulley marks are aligned with the
seal plate marks.
If not aligned, remove the timing belt and repeat from ten-
sioner installation.
7. Turn the crankshaft 1 and 5/6 turns clockwise, and align
the timing belt pulley mark with the tension set mark for prop-
er timing belt tension adjustment.
8. Loosen the tensioner lock bolt to apply tension to the tim-
ing belt.
9. Tighten the tensioner lock bolt.
Tightening torque:
37-52 N-m (3.8-5.3 m-kg, 27-38 ft-lb)
10. Turn the crankshaft 2 and l/6 turns clockwise and verify
that the timing marks are correctly aligned.

4. Loosen the two attaching screws.
5. Rotate the throttle sensor clockwise
approx. 30 degrees,
then rotate it back counterclockwise until the continuity
exists.
6. Replace the feeler gauge with a
0.7mm (0.027 in) gauge.
7. Verify that the continuity does not exist.
8. If it exists, repeat Steps 3 through 6. ‘-
9. Tighten the two attaching screws.
Note
l Do not move the throttle sensor from the set posi-
tion when tightening the screws.
10. Open the throttle valve fully a few times.
11. Recheck the adjustment of the throttle sensor.
Adjustment (ATX)
1. Disconnect the connector from the throttle sensor.
2. Connect an ohmmeter between the throttle sensor termi-
nals E and IDL.
3. Loosen the two attaching screws.
4. Insert a
0.25mm (0.01 in) feeler gauge between the throt-
tle stop screw and the stop lever.
5. Rotate the throttle sensor clockwise
approx. 30 degrees,
then rotate it back counterclockwise until there is continuity. i-
6. Replace the feeler gauge with a
0.4mm (0.016 in) gauge
and verify that there is no continuity.
7. If there is continuity, repeat Steps 4 through 6.
8. Tighten the two attaching screws.
Note
l Do not move the throttle sensor from the set posi-
tion when tightening the screws.
9. Open the throttle valve fully and verify that the resistance
between the throttle sensor terminals E and VT is
approx.
5 kQ.

Caution
l Connect all charging hoses via stop valves to avoid
venting the refrigerant remaining in the hoses into
the atomosphere. _A
l Do not disconnect the stop valve from the charg-
ing hose when there is refrigerant remaining in the
hose.
1. Turn the knob counterclockwise to close the stop valve.
2. Install the stop valve to the end of the charging hose of the
manifold gauge set.
Caution
l Verify that high-and low-pressure side valves of the
manifold gauge set are fully closed before connect-
ing the charging hose and stop valve to the refriger-
ant system service valve.
23UOUX-063 Evacuation/Airtiahtness test
1. Connect the manifold gauge set and stop valves to the
refrigerant system service valves.
2. Connect the center hose of the manifold gauge set to the
vacuum pump inlet.
3. Prepare as follows according to the charging method.
Charging from service container.
Connect the charging hose and service container valve to the
manifold gauge set air purge valve.

Refrigerant recovery operation.
Remove the refrigerant from the refrigerant system by using
a freon (refrigerant) recovery and recycling system.
Caution
. Never vent the refrigerant into the atomosphere.
l When using a freon recovery and recycling system,
follow the operation instructions provided by the
equipment manufacturer.
