Checking Drive BeltsINFOID:0000000001337777
WARNING:
Be sure to perform this step when the engine is stopped.
 Make sure that the indicator (notch on fixed side) of drive belt auto-tensioner is within the possible use range
(A).
NOTE:
 Check the drive belt auto-tensioner indication when the engine is cold.
 When new drive belt is installed, the indicator (notch on fixed side) should be within the range (B).
 Visually check entire drive belt for wear, damage or cracks.
 If the indicator (notch on fixed side) is out of the possible use range or belt is damaged, replace drive belt.
Tension AdjustmentINFOID:0000000001337778
Belt tension is not necessary, as it is automatically adjusted by drive belt auto-tensioner.
Removal and InstallationINFOID:0000000001337779
REMOVAL
1. Hold the hexagonal part (A) of drive belt auto-tensioner (1) with
a wrench securely. Then move the wrench handle in the direc-
tion of arrow (loosening direction of tensioner).
CAUTION:
Never place hand in a location where pinching may occur if
the holding tool accidentally comes off.
2. Insert a rod such as short-length screwdriver approximately 6
mm (0.24 in) in diameter into the hole (B) of the retaining boss to
fix drive belt auto-tensioner.
3. Remove drive belt.
INSTALLATION

1. Hold the hexagonal part (A) of drive belt auto-tensioner (1) with
a box wrench securely. Then move the wrench handle in the
direction of arrow (loosening direction of tensioner).
CAUTION:
Never place hand in a location where pinching may occur if
the holding tool accidentally comes off.
2. Insert a rod such as short-length screwdriver approximately 6
mm (0.24 in) in diameter into the hole (B) of retaining boss to fix
drive belt auto-tensioner.
3. Install drive belt.
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-142, "
Checking Drive Belts".

COMPRESSION PRESSURE
Checking Compression PressureINFOID:0000000001346452
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to EC-1035, "
Inspection".
3. Disconnect fuel pump fuse (1) to avoid fuel injection during mea-
surement.
4. Remove engine cover. Refer to EM-156, "
Component".
5. Remove ignition coil and spark plug from each cylinder. Refer to EM-145, "
Removal and Installation".
6. Connect an engine tachometer (not required in use of CONSULT-III).
7. Install a suitable compression tester with an adapter 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.
Compression pressure:
Unit: kPa (bar, kg/cm2 psi) /rpm
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 engine
speed again with normal battery gravity.

COMPRESSION PRESSURE
 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.
9. After inspection is completed, install removed parts.
10. Start the engine, and confirm that the engine runs smoothly.
11. Perform trouble diagnosis. If DTC appears, erase it. Refer to EC-781, "
Description".

tortion of exhaust manifold mating surface in each exhaust port
and entire part.
 If it exceeds the limit, replace exhaust manifold.
