DRIVE BELTS
CAUTION:
 When the lock nut is loosened excessively, the idler pulley tilts and the correct tension adjust-
ment cannot be performed. Never loosen it excessively (more than 45 degrees).
 Put a matching mark on the lock nut, and check turning angle with a protractor. Never visually
check the tightening angle.
2. Adjust the belt tension by turning the adjusting bolt.
CAUTION:
 When checking immediately after installation, first adjust it to the specified value. Then, after
turning crankshaft two turns or more, re-adjust to the specified value to avoid variation in deflec-
tion between pulleys.
 When the tension adjustment is performed, the lock nut should be in the condition at step“2”. If
the tension adjustment is performed when the lock nut is loosened more than the standard, the
idler pulley tilts and the correct tension adjustment cannot be performed.
3. Tighten the idler pulley lock nut.

REMOVAL
1. Loosen the idler pulley lock nut (A), and then adjust the belt ten-
sion by turning the adjusting bolt (B).
2. Remove drive belt.
INSTALLATION
1. Pull the idler pulley in the loosening direction, and then tempo-
rarily tighten the idler pulley lock nut (A) to the following torque.
NOTE:
Do not move the lock nut from the tightened position. Proceed to step “2”.
2. Install the drive belt to each pulley.
CAUTION:
 Make sure that there is no oil, grease, or coolant, etc. in pulley grooves.
 Make sure that the belt is securely inside the groove on each pulley.
3. Adjust drive belt tension by turning the adjusting bolt. Refer to EM-15, "
Tension Adjustment".

COMPRESSION PRESSURE
COMPRESSION PRESSURE
InspectionINFOID:0000000001381392
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to EC-377, "
Inspection" (EURO-OBD), EC-681, "Inspection" (WITHOUT
EURO-OBD).
3. Remove ignition coil and spark plug from each cylinder. Refer to EM-47, "
Exploded View".
4. Connect an engine tachometer (not required in use of CONSULT-III).
5. Install a compression tester (B) with an adapter (commercial
service tool) (A) 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.
6. 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 fully a changed battery to obtain the specified engine speed.
 If the engine speed is out of the 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
combustion chamber (Valve, valve seat, piston, piston ring, cylinder bore, cylinder head, cylinder head
gasket). After the checking, measure the 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 re-check 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 gasket is leaking. In such a case, replace cylinder
head gasket.
7. After inspection is completed, install removed parts.
8. Start the engine, and confirm that the engine runs smoothly.
9. Perform trouble diagnosis. If DTC appears, erase it. Refer to EC-469, "
Description".
