INSPECTION

COMPESSION PRESSURE

If there is lack of power, excessive oil consumption or poor fuel economy, measure the compression pressure.

1. Warm up the engine until the coolant temperature becomes 80~95°C(176~203°F).

2. Remove the fuel inlet(A) and the return hose(B) from the fuel filter.

3. Crank the engine in order to exhaust fuel in the high pressure pump.

Gather residual fuel by putting the return hose into a proper vessel.

4. Remove the injection pipe, injector and washer.(Refer to FL group).

5. Measure the cylinder compression pressure.

(1) Insert the SST(0K552 131 002) into the injector hole.

(2) Cranking the engine, measure the pressure.

Use the complete charging battery for the engine to crank at the speed of 350rpm or more.

(3) Do the above step 1)~2) again for each cylinder.

This work must be done in as short time as possible.

Compression pressure :
3040.05kPa (31kg/cm², 440.92psi) (325 rpm)
Minimum pressure :
2745.85kPa (28kg/cm², 398.25psi)
Difference between each cylinder :
294.20kPa (3.0kg/cm², 42.67psi)

(4) If, in one or more cylinders, the measured value is below the limit, fill a little engine oil into the injector holes of

the cylinders, repeat the step 1)~2) and measure the compression pressure again.

a. If the re-measured pressure becomes higher, wear or damage of the piston ring or cylinder surface can be

the cause.

b. If the re-measured pressure does not become higher, adherence or poor contact of the valves or inferior

gasket can be the cause.

gasket can be the cause.

6. Install the injectors, washers and the injector pipes.(Refer to FL group).

7. Install the inlet and the return hoses to the fuel filter.

TIMING BELT TENSION ADJUSTMENT

1. Remove the battery terminals (A).

2. Install the jack for oil pan.

3. Remove the engine mounting (A).

4. Remove the engine support bracket(A).

5. Remove the drive belt.

6. Remove the water pump pulley.

7. Remove the bolts(B), nut(C) and timing belt upper cover (A).

8. Turn the crankshaft pulley(A) and align its groove with the timing mark “T” of the timing belt cover. Check that the

timing mark of camshaft sprocket(B) is aligned with that of the cylinder head cover. (No.1 cylinder positioned at the
TDC position)

9. Remove the crankshaft pulley bolt(A), washer(B) and crankshaft pulley(C).

Using the special tool(09517-21700, 09231-H1000), fix the crankshaft pulley and loosen the bolt(A).

10. Remove the drive belt idler(A).
