INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.
lBefore starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer toMA-14, "
RECOMMENDED FLUIDS AND LUBRICANTS".
lUse procedure below to check for fuel leakage.
–Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
–Start engine. With engine speed increased, check again for fuel leakage at connection points.
lRun engine to check for unusual noise and vibration.
lWarm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids
including engine oil and engine coolant.
lBleed air from lines and hoses of applicable lines, such as in cooling system.
lAfter 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:
*1: Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.
*2: Check engine oil level 10 minutes after engine stopped.

CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Using CONSULT-II, make sure no error codes are indicated for self-diagnosis items. Refer toEC-38,
"Basic Inspection".
lDo not disconnect CONSULT-II until the end of this operation; it will be used to check engine rpm and
for error detection at the end of this operation.
3. Disconnect the battery cable from the negative terminal.
4. To prevent fuel from being injected during inspection, remove fuse [EGI (20A)] (1) from fuse box.
5. Remove glow plugs from all the cylinders. Refer toEM-41, "
GLOW PLUG".
CAUTION:
lBefore removal, clean the surrounding area to prevent entry of any foreign materials into
engine.
lCarefully remove glow plugs to prevent any damage or breakage.
lHandle with care to avoid applying any shock to glow plugs.
6. Install compression gauge adapter [SST] to installation holes of
glow plugs and connect compression gauge for diesel engine.
7. Connect the battery cable to the negative terminal.
8. With accelerator pedal fully depressed, turn ignition switch to
“START” for cranking. When the gauge pointer stabilizes, read
the compression pressure and engine rpm. Perform these steps
to check each cylinder.
lAlways use a fully-charged battery to obtain specified engine
speed.

Compression pressure
Unit: kPa (bar, kg/cm2, psi)/rpm
lWhen engine rpm is out of the specified range, check the specific gravity of battery liquid. Measure
again under corrected conditions.
lIf engine rpm exceeds the limit, check valve clearance and combustion chamber components (valves,
valve seats, cylinder head gaskets, piston rings, pistons, cylinder bores, cylinder block upper and lower
surfaces) and measure again.
lIf compression pressure is low in some cylinders, apply engine oil from glow plug installation hole. Then
check pressure again.
–If compression pressure becomes normal after applying engine oil, piston ring may be worn or dam-
aged. Check piston ring for malfunction. If any, replace piston ring.
–If compression pressure is still low after applying engine oil, valve may be malfunctioning. Check valve
for malfunction. If contact malfunction is found, replace valve or valve seat.
lIf compression pressure in adjacent two cylinders is low after applying engine oil, pressure may be
leaking from gasket. In this case, replace cylinder head gasket.
9. Complete this operation as follows:
a. Turn the ignition switch to “OFF”.
b. Disconnect the battery cable from the negative terminal.
c. Install glow plug and install all the parts removed in step 4.
d. Install fuse [EGI (20A)].
e. Connect the battery cable to the negative terminal.
f. Using CONSULT-II make sure no DTC is indicated for items of self-diagnosis.

*: Measured with head bolts tightened
e. If out of above protrusion, check replaced parts.
2. Apply a continuous bead of liquid gasket with the tube presser
[SST: WS39930000] as shown in the figure.
A: Apply bead so that it does not protrude into oil passage.
B: Minimize the overlapping area of the bead, with start and end
areas of bead as shown in the figure.
Apply so that the portion marked * comes at an external loca-
tion but cannot be viewed externally after engine is assembled.
3. Install cylinder head assembly.
lTighten bolts in numerical order as shown in the figure
according to the following procedure:
a. Apply engine oil to bolt threads and seat surfaces.
b. Tighten all bolts.
c. Tighten 180 degrees (angle tightening).
d. Loosen completely in the reverse order of that shown in the fig-
ure.
e. Tighten all bolts.
f. Tighten 90 degrees (angle tightening).
g. Tighten another 90 degrees (angular tightening).
CAUTION:
lWhen the angle wrench [SST] is not used, paint an alignment mark on the head of cylinder head
bolt and cylinder head surface before tightening. Check the angle with a protractor.
4. After installing cylinder head, measure dimension from the front
end surface of cylinder block to that of cylinder head.
lIf out of the standard, check fitting of dowel pins and cylinder
head.
5. Install glow plug.
CAUTION:
lTo avoid damage, glow plugs should be removed only when required.
lHandle with care to avoid applying shock. When dropped from approx. 10 cm (3.94 in) or higher,
always replace with a new one.
