3. 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 drive belt).
CAUTION:
 Avoid placing hand in a location where pinching may
occur if the holding tool accidentally comes off.
 Never loosen the hexagonal part in center of drive belt
auto-tensioner pulley (Never turn it counterclockwise). If
turned counterclockwise, the complete drive belt auto-
tensioner must be replaced as a unit, including the pulley.
4. Insert a rod approximately 6 mm (0.24 in) in diameter such as
short-length screwdriver into the hole (A) of the retaining boss to
fix drive belt auto-tensioner pulley.
 Keep drive belt auto-tensioner pulley arm locked after drive belt is removed.
5. Loosen drive belt from water pump pulley in sequence, and remove it.
INSTALLATION
1. Hook drive belt on to all pulleys except for drive belt auto-tensioner pulley, and then onto drive belt auto-
tensioner 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.
2. Release drive belt auto-tensioner, and apply tension to drive belt.
3. Turn crankshaft pulley clockwise several times to equalize tension between each pulley.
4. Confirm tension of drive belt at indicator is within the possible use range. Refer to EM-12, "
Exploded
View".

COMPRESSION PRESSURE
COMPRESSION PRESSURE
InspectionINFOID:0000000003802245
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to EC-411, "
Inspection".
3. Disconnect fuel pump fuse to avoid fuel injection during measurement. Refer to EC-20,
"ComponentPartsLocation".
4. Remove engine cover. Refer to EM-24, "
Exploded View".
5. Remove ignition coil and spark plug from each cylinder. Refer to EM-49, "
Exploded View".
6. Connect engine tachometer (not required in use of CONSULT-III).
7. Install compression gauge with an adapter (commercial service
tool) onto spark plug hole.
 Use the adapter whose picking up end inserted to spark plug
hole is smaller than 20 mm (0.79 in) in diameter. Otherwise, it
may be caught by cylinder head during removal.
8. With accelerator pedal fully depressed, turn ignition switch to “START” for cranking. When the gauge
pointer stabilizes, read the compression pressure and the engine rpm. Perform these steps to check each
cylinder.
CAUTION:
Always use a fully charged battery to obtain the specified engine speed.
 If the engine speed is out of the specified range, check battery liquid for proper gravity. Check the
engine speed again with normal battery gravity.
 If compression pressure is below minimum value, check valve clearances and parts associated with
combustion chamber (valve, valve seat, piston, piston ring, cylinder bore, cylinder head, cylinder head
gasket). After the checking, measure compression pressure again.
 If some cylinder has low compression pressure, pour small amount of engine oil into the spark plug hole
of the cylinder to recheck it for compression.
- If the added engine oil improves the compression, piston rings may be worn out or damaged. Check pis-
ton rings and replace if necessary.
- If the compression pressure remains at low level despite the addition of engine oil, valves may be mal-
functioning. Check valves for damage. Replace valve or valve seat accordingly.
 If two adjacent cylinders have respectively low compression pressure and their compression remains
low even after the addition of engine oil, cylinder head gaskets are leaking. In such a case, replace cyl-
inder head gaskets.
9. After inspection is completed, install removed parts.

TIMING CHAIN
CAUTION:
Never overtighten slack guide mounting bolt (2). It is nor-
mal for a gap (A) to exist under the bolt seat when mounting
bolt is tightened to specification.
7. Install the timing chain tensioner (primary) with the following procedure:
a. Pull plunger stopper tab (A) up (or turn lever downward) so as to
remove plunger stopper tab from the ratchet of plunger (D).
NOTE:
Plunger stopper tab and lever (C) are synchronized.
