CheckingINFOID:0000000001381384
 Inspection should be done only when engine is cold or over 30
minutes after the engine is stopped.
 Visually check belts for wear, damage, and cracks on inside and
edges.
 Turn crankshaft pulley two time clockwise, and make sure tension on all pulleys is equal before doing the
test.
 When measuring deflection, apply 98 N (10 kg, 22 lb) at the ( ) marked point.
 Measure the belt tension and frequency with acoustic tension gauge (commercial service tool) at the ( )
marked point.
CAUTION:
 When the tension and frequency are measured, the acoustic tension gauge should be used.
 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 deflection
between pulleys.
Tension AdjustmentINFOID:0000000001381385
CAUTION:
 When belt is replaced with new one, adjust belt tension to the value for “New belt”, because new belt
will not fully seat in the pulley groove.
 When tension of the belt being used exceeds “Limit”, adjust it to the value for “After adjusted”.
 When installing a belt, make sure it is correctly engaged with the pulley groove.
 Never allow oil or engine coolant to get on the belt.
 Never twist or bend the belt strongly.
1. Loosen the idler pulley lock nut (A) from the tightening position
with the specified torque by 45 degrees.

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.

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".

P O Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak.
 Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-19, "
Fluids and Lubricants".
 Use procedure below to check for fuel leakage.
- Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
- Start engine. With engine speed increased, check again for fuel leakage at connection points.
 Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in the guide may
generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after
hydraulic pressure rises.
 Warm up engine thoroughly to make sure there is no leakage of fuel, or any oil/fluids including engine oil and
engine coolant.
 Bleed air from lines and hoses of applicable lines, such as in cooling system.
 After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
Summary of the inspection items:
*: Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.
