WARNING:
Do not remove radiator cap and/or reservoir tank cap when engine is hot. Serious burns could occur
from high pressure engine coolant escaping from radiator and/or reservoir tank.
REMOVAL
1. Remove front engine undercover and middle engine undercover. Refer toEI-15, "FRONT BUMPER".
2. Drain engine coolant from radiator drain plug at the bottom of radiator, and from water drain plug at the
side of cylinder block. Refer toCO-7, "
Changing Engine Coolant"andEM-110, "CYLINDER BLOCK".
CAUTION:
Perform this step when engine is cold.
3. Remove engine cover. Refer toEM-20, "
INTAKE MANIFOLD".
4. Disconnect radiator hoses (upper and lower) from engine side. Refer toCO-11, "
RADIATOR".
5. Remove air inlet pipe and air duct between air cleaner case and turbocharger. Refer toEM-15, "
AIR
CLEANER AND AIR DUCT"andEM-28, "TURBO CHARGER".
6. Remove water outlet, water inlet and thermostat.
7. Remove thermostat housing.
8. Disconnect heater return hose and water hoses at heater return pipe side, and remove heater return pipe.
9. Remove oil level gauge guide mounting bolt, vacuum hoses (to turbocharger boost control solenoid valve)
and spill hose. Refer toEM-36, "
OIL PAN AND OIL STRAINER",EM-20, "INTAKE MANIFOLD"andEM-
44, "INJECTION TUBE AND FUEL INJECTOR".
10. Disconnect water hoses (to EGR cooler) (A/T models), vacuum hoses and heater feed hose at heater
feed pipe side, and remove heater feed pipe. Refer toEM-20, "
INTAKE MANIFOLD".
INSPECTION AFTER REMOVAL
Thermostat
lPlace a string so that it is caught in the valves of the thermostat.
Immerse fully in a container filled with water. Heat while stirring.
lThe valve opening temperature is the temperature at which the
valve opens and falls from the thread.
lContinue heating. Check the full-open lift amount.
lAfter checking the full-open lift amount, lower the water temper-
ature and check the valve closing temperature.
Standard values
lIf out of the standard, replace thermostat.
INSTALLATION
Note the following, and install in the reverse order of removal.
lSecurely insert each hose, and install clamp at a position where it does not interfere with the pipe bulge.
lWhen inserting heater feed pipe end into cylinder head, apply a neutral detergent to O-ring. Then insert it
immediately.

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.
