DRIVE BELTS
4. Remove drive belt.
 Turn drive belt auto-tensioner adjusting bolt clockwise to
release drive belt tension.
INSTALLATION
1. Install the drive belt.
CAUTION:
 Make sure drive belt is correctly engaged with the pulley
groove.
 Check for oil and coolant on drive belt and each pulley
groove.
 Certain drive belts have five teeth whereas the air condi-
tioning compressor pulley, power-assisted steering pump
pulley, and generator pulley all have six teeth.In this case,
it is essential to check that inner tooth (O) of the pulleys
remains free when fitting the drive belt.
Never turn the engine in the opposite direction to its nor-
mal operating direction.
Use a brush to remove any deposits from the crankshaft
pulley V grooves.
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.

COMPRESSION PRESSURE
InspectionINFOID:0000000001381466
1. Warm up engine thoroughly. Then stop.
2. Remove glow plug.
3. Disconnect high-pressure supply pump harness connector to avoid fuel injection during measurement.
4. Connect compression gauge attachment hose [SST:
KV113B0400 (Mot. 1592)] (A) to the hole for glow plug.
5. Connect compression gauge (B) to attachment hose (A).
6. Turn ignition switch to START for cranking and check compres-
sion gauge.
7. Perform the same procedure for the other cylinders.
 If compression pressure is below minimum value, check valve
clearances and parts associated with combustion chamber (valve, valve seat, piston, piston ring, cylin-
der bore, cylinder head, cylinder head gasket). After checking, measure compression pressure again.
 If any cylinder has low compression pressure, pour a small amount of engine oil into the glow 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 gaskets are leaking. In this case, replace cylinder
head gaskets.
8. Disconnect compression gauge (B) and attachment hose (A).
9. After inspection is completed, install removed parts.
10. Start the engine, and make sure that the engine runs smoothly.
11. Perform trouble diagnosis. If DTC appears, erase it. Refer to EC-1043, "
BASIC INSPECTION : Descrip-
tion". Compres-
sion pres-
sure: Refer to EM-333,
"GeneralSpecification".

CleaningINFOID:0000000001381511
 It is very important not to scratch the gasket faces of any aluminium components.
 Use suitable tool to dissolve any part of the seal which remains stuck to the metal surface.
 Apply the dissolving product to the part to be cleaned, wait approximately 10 minutes, then remove it using a
wooden spatula.
 Wear gloves while carrying out this operation.
 Do not allow this dissolving product to drip on to the paintwork.
Great care should be taken when performing this operation, to prevent foreign objects from entering
the pipes taking oil under pressure to the camshafts (pipes in both the cylinder head and its cover)
and the oil return pipes.
Failure to follow these instructions could lead to the blocking of the oilways, resulting in rapid and
serious damage to the engine.

INSPECTION AFTER REMOVAL
Cylinder Head Distortion
NOTE:
When performing this inspection, cylinder block distortion should be also checked. Refer to EM-330, "
Inspec-
tion".
