INSTALLATION
1. With box wrench, and while securely holding the hexagonal part in pulley center of drive belt auto-ten-
sioner, move the wrench handle 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.
2. Insert a rod approximately 6 mm (0.24 in) in diameter into retaining boss to fix auto-tensioner pulley.
3. Hook drive belt onto all pulleys except for water pump. Hook drive belt onto water pump pulley at the end.

INSPECTION
●When the camshaft or parts in connection with valves are
removed or replaced, and a malfunction has occurred (poor
starting, idling, or other malfunction) due to the misadjustment of
the valve clearance, inspect as follows.
●Inspect and adjust when the engine is cool (at normal tempera-
ture).
●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 an intake valve or an
exhaust valve.(Refer to illustration)
1. Drain engine coolant. Refer to CO-29, "
Changing Engine Coolant" .
2. Remove charge air cooler. Refer to EM-122, "
Removal and Installation" .
3. Remove air duct and air inlet pipe. Refer to EM-120, "
Removal and Installation" .
4. Remove rocker cover. Refer to EM-156, "
Removal and Installation" .
5. Remove vacuum pump. Refer to EM-139, "
Removal and Installation" .
6. Remove injection tube and fuel injector. Refer to EM-144, "
Removal and Installation" .
7. Remove secondary timing chain. Refer to EM-167, "
Removal and Installation"
Check valve clearance while engine is cold and not running.
8. Set the No. 1 piston to TDC on its compression stroke.
●Turn crankshaft pulley clockwise so that the knock pin on
camshaft LH faces straight above. (No position indicator, etc.
is provided on the crankshaft pulley.)
9. Put an alignment mark with paint, etc. on the crankshaft pulley
and on the oil pump as an angle indicator.
10. While referring to the figure, measure the valve clearance
marked in the table below.
●The injection order is 1-3-4-2.

●Measure the valve clearance using a fine feeler gauge when
the engine is cool (at normal temperature).
11. Set the No. 4 cylinder at TDC by rotating the crankshaft clock-
wise once.
12. While referring to the figure, measure the valve clearance
marked in the table below.
13. If the valve clearance is outside the specification, adjust as fol-
lows.
ADJUSTMENTS
●Remove the adjusting shim for parts which are outside the spec-
ified valve clearance.
1. Remove the spill tube. Refer to EM-144, "
Removal and Installa-
tion" .
2. Extract the engine oil on the upper side of the cylinder head (for
the air blowing in step 7).
3. Rotate the crankshaft to face the camshaft for adjusting shims
that are to be removed upward.
4. Grip the camshaft with camshaft pliers, them using the camshaft
as a support point, push the adjusting shim downward to com-
press the valve spring.
CAUTION:
Do not damage the camshaft, cylinder head and the outer
circumference of the valve lifter.Valve clearance (Cold):
Standard:
Intake : 0.24 - 0.32 mm (0.0094 - 0.0126 in)
Exhaust : 0.26 - 0.34 mm (0.0102 - 0.0134 in)

If the ECM is in Diagnostic Test Mode II, MI may flash when engine is running. In this case, check ECM diag-

HOW TO SWITCH DIAGNOSTIC TEST MODE" .
How to switch the diagnostic test (function) modes, and details of the above functions are described later, EC-
59 .
The following emission-related diagnostic information is cleared when the ECM memory is erased.
1. Diagnostic trouble codes
2. 1st trip diagnostic trouble codes
3. Freeze frame data
4. 1st trip freeze frame data
5. System readiness test (SRT) codes
6. Test values
7. Others
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.
