INSTALLATION
1. Hold the hexagonal part in center of drive belt auto-tensioner
pulley with a box wrench securely. Then move the wrench han-
dle in the direction of arrow (loosening direction of tensioner).
CAUTION:
Avoid placing hand in a location where pinching may
occur if the holding tool accidentally comes off.
Do not loosen the hexagonal part in center of drive belt
auto-tensioner pulley (Do not turn it counterclockwise). If
turned counterclockwise, the complete drive belt auto-
tensioner must be replaced as a unit, including the pul-
ley.
2. Insert a rod approximately 6 mm (0.24 in) in diameter such as
short-length screwdriver into the hole of retaining boss to fix drive belt auto-tensioner pulley.
3. Hook drive belt onto all pulleys except for water pump, and then onto water pump pulley finally.
CAUTION:
Confirm drive belt is completely set to pulleys.
Check for engine oil, working fluid and engine coolant are not adhered to drive belt and each
pulley groove.
4. Release drive belt auto-tensioner, and apply tension to drive belt.
5. Turn crankshaft pulley clockwise several times to equalize tension between each pulley.
6. Confirm tension of drive belt at indicator (notch on fixed side) is within the possible use range. Refer to
EM-13, "
Checking Drive Belts" .

Be careful of the intake and exhaust valve arrangement. The
valve arrangement is different from that in a normal engine.
NOTE:
The camshafts have, alternately, either intake valve or exhaust
valve. (Refer to figure.)
1. Remove charge air cooler. Refer to EM-144, "
Removal and Installation" .
2. Remove air duct. Refer to EM-142, "
Removal and Installation" .
3. Remove rocker cover. Refer to EM-178, "
Removal and Installation" .
4. Remove fuel injector. Refer to EM-167, "
Removal and Installation" .
5. Set the No. 1 piston to TDC on its compression stroke.
Turn crankshaft pulley clockwise so that the knock pin on
camshaft left side faces straight above. (No position indicator,
etc. is provided on the crankshaft pulley.)
6. Put an alignment mark with paint, etc. on crankshaft pulley and
on oil pump housing as an angle indicator.
7. While referring to the figure, measure the valve clearance
marked in the table below.
NOTE:
The injection order is 1-3-4-2.

Measure the valve clearance using the feeler gauge when
engine is cool (at normal temperature).
Valve clearance:
Unit: mm (in)
*: Reference data approximately 80°C (176°F)
8. Set the No. 4 cylinder at TDC by rotating the crankshaft clockwise once. (360 degrees)
9. While referring to the figure, measure the valve clearance
marked in the table below.
10. If the valve clearance is outside the specification, adjust as follows.
ADJUSTMENTS
Remove adjusting shim for parts which are outside the specified valve clearance.
1. Extract engine oil on the upper side of the cylinder head (for the air blowing in step 6).
2. Rotate crankshaft to face the camshaft for adjusting shims that
are to be removed upward.

SECONDARY TIMING CHAIN
Loosen fixing bolts in reverse order of that shown in the figure
and remove them.
Remove No. 6, 10 and 11 bolts with the rubber washer as
space is limited for pulling them out.
CAUTION:
While front chain case is removed, cover openings to
prevent entry of foreign material into engine.
Do not remove two mass dampers on the back of
cover.
5. Set the No. 1 piston to TDC on its compression stroke.
Turn crankshaft pulley clockwise so that the alignment mark
(punched mark) on each camshaft sprocket is positioned as
shown in the figure.
No position indicator is provided on crankshaft pulley.
When installing, color coded links on secondary timing
chain can be used as alignment marks. Marking may not
be necessary for removal; however, make alignment
marks as required because the alignment mark on fuel
pump sprocket may not be easy to see.
6. Remove chain tensioner as follows:
a. Push the plunger of chain tensioner and keep it pressed with a
push pin.

ON BOARD DIAGNOSTIC (OBD) SYSTEM
HOW TO SWITCH DIAGNOSTIC TEST MODE
NOTE:
It is better to count the time accurately with a clock.
It is impossible to switch the diagnostic mode when an accelerator pedal position sensor circuit
has a malfunction.
Always ECM returns to Diagnostic Test Mode I after ignition switch is turned OFF.
How to Set Diagnostic Test Mode II (Self-diagnostic Results)
1. Confirm that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds.
2. Repeat the following procedure quickly five times within 5 seconds.
a. Fully depress the accelerator pedal.
b. Fully release the accelerator pedal.
3. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the MI starts
blinking.
4. Fully release the accelerator pedal.
ECM has entered to Diagnostic Test Mode II (Self-diagnostic results).
How to Set Diagnostic Test Mode II (Heated Oxygen Sensor 1 Monitor)
1. Set the ECM in Diagnostic Test Mode II (Self-diagnostic results). Refer to EC-66, "How to Set Diagnostic
Test Mode II (Self-diagnostic Results)" .
2. Start Engine.
ECM has entered to Diagnostic Test Mode II (Heated oxygen sensor 1 monitor).
How to Erase Diagnostic Test Mode II (Self-diagnostic Results)
1. Set ECM in Diagnostic Test Mode II (Self-diagnostic results). Refer to EC-66, "How to Set Diagnostic Test
Mode II (Self-diagnostic Results)" .
2. Fully depress the accelerator pedal and keep it for more than 10 seconds.
The emission-related diagnostic information has been erased from the backup memory in the ECM.
3. Fully release the accelerator pedal, and confirm the DTC 0000 is displayed.
DIAGNOSTIC TEST MODE I — BULB CHECK
In this mode, the MI on the instrument panel should stay ON. If it remains OFF, check the bulb. Refer to DI-35,
"WARNING LAMPS" or see EC-518, "MI & DATA LINK CONNECTORS" .
DIAGNOSTIC TEST MODE I — MALFUNCTION WARNING
These DTC numbers are clarified in Diagnostic Test Mode II (SELF-DIAGNOSTIC RESULTS)
DIAGNOSTIC TEST MODE II — SELF-DIAGNOSTIC RESULTS
In this mode, the DTC and 1st trip DTC are indicated by the number of blinks of the MI as shown below.
The DTC and 1st trip DTC are displayed at the same time. If the MI does not illuminate in diagnostic test mode
I (Malfunction warning), all displayed items are 1st trip DTCs. If only one code is displayed when the MI illumi-
nates in diagnostic test mode II (SELF-DIAGNOSTIC RESULTS), it is a DTC; if two or more codes are dis-
played, they may be either DTCs or 1st trip DTCs. DTC No. is same as that of 1st trip DTC. These unidentified
