●Before inspecting the engine, make sure the engine has cooled down; wait approximately 30 minutes
after the engine has been stopped.
●Visually inspect all belts for wear, damage, or cracks on contacting surfaces and edge areas.
●When measuring deflection, apply 98 N (10 kg, 22 lb) at the ▼ marked point.
CAUTION:
When measuring belt tension immediately after belt is installed, first set the tension to the standard.
Then, rotate crankshaft for more than two turns in order to eliminate variance in belt deflection
between the pulleys. Re-measure and adjust the tension to the standard.

Tension Adjustment
EBS00LPZ
CAUTION:
●When belt is replaced with a new one, tighten it a little
stronger than current one to accommodate for insufficient
adaptability with pulley grooves.
●When tension of belt being used exceeds “Retightening
limit”, adjust it to value for “Used belt”.
●When installing belt, make sure that it is correctly engaged with pulley groove.
●Keep oil and water away from belt.
●Do not twist or bend belt excessively.
●When adjusting belt, remove snap retainer from adjusting bolt thread (to prevent the retainer from
becoming pinched or missing).
●After adjustment, be sure to install snap retainer to adjusting bolt thread.
NOTE:
Snap retainer can prevent adjusting bolt from dropping due to vibration during driving.

CAUTION:
Do not touch fuel injector nozzle with intake manifold or other parts.
5. Remove fuel injector from fuel tube.
●Release clip and remove it.
●Pull fuel injector straight out of fuel tube.
CAUTION:
●Be careful not to damage nozzle part.
●Avoid any impact such as a dropping.
●Do not disassemble or adjust it.
INSTALLATION
1. When installing O-ring to fuel injector, follow instructions described below.
CAUTION:
●Handle O-ring with bare hands. Never wear gloves.
●Lubricate O-ring with new engine oil.
●Do not clean O-ring with solvent.
●Make sure that O-ring and its mating part are free of foreign material.
●Be careful not to scratch it with a tool or fingernails during installation. Also be careful not to
twist or stretch O-ring. If O-ring is stretched while being attached, do not insert it into fuel tube
immediately.
●Insert O-ring straight into fuel tube. Do not angle or twist it.
2.
Install fuel injector to fuel tube with the following procedure.
a. Insert clip into clip mounting groove on fuel injector.
●Insert clip so that lug “A” of fuel injector matches notch “A” of
the clip.
CAUTION:
●Do not reuse clip. Replace it with a new one.
●Be careful to keep clip from interfering with O-ring. If
interference occurs, replace O-ring.
b. Insert fuel injector into fuel tube with clip attached.
●Insert it while matching it to the axial center.
●Insert fuel injector so that lug “B” of fuel tube matches notch
“B” of the clip.
●Make sure that fuel tube flange is securely fixed in flange fix-
ing groove on clip.
c. Make sure that installation is complete by checking that fuel
injector does not rotate or come off.

CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to EC-34, "
FUEL PRESSURE RELEASE" (WITH EURO-OBD), EC-427,
"FUEL PRESSURE RELEASE" (WITHOUT EURO-OBD).
3. Remove ignition coil and spark plug from each cylinder.
Refer to IGNITION COIL EM-24, "
Removal and Installation" and SPARK PLUG EM-25, "Removal and
Installation" .
4. Connect engine tachometer (not required in use of CONSULT-II).
5. Disconnect fuel injector harness connector so that no fuel is injected.
6. Install compression tester with adapter onto spark plug hole.
●Use compression gauge 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.
7. With accelerator pedal fully depressed, turn ignition switch to
“START” for cranking. When the gauge pointer stabilizes, read
the compression pressure and engine rpm. Perform these steps
to check each cylinder.
Compression pressure
[kPa (bar, kg/cm2 , psi)/rpm]
CAUTION:
Always use a fully changed battery to obtain specified engine speed.
●If the engine speed is out of specified range, check battery liquid for proper gravity. Check engine speed
again with normal battery gravity.
●If compression pressure is below minimum value, check valve clearances and parts associated with com-
bustion chamber (Valve, valve seat, piston, piston ring, cylinder bore, cylinder head, cylinder head gas-
ket). After the checking, measure compression pressure again.
●If some cylinders have low compression pressure, pour small amount of engine oil into the spark plug hole
of the cylinder to re-check it for compression.
–If the added engine oil improves the compression, the piston rings may be worn out or damaged. Check
the piston rings and replace if necessary.
–If the compression pressure remains at low level despite the addition of engine oil, the valves may be mal-
functioning. Check the valves for damage. Replace the 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, the gaskets are leaking. In such a case, replace the cylinder head
gaskets.
