ENGINE COOLING – Thermostat14-4
INSTALLATION SERVICE POINTS
ATHERMOSTAT INSTALLATION
(1) Install the thermostat so that the jiggle valve is facing
straight up.
Caution
Make absolutely sure that no oil is adhering to the
rubber ring of the thermostat. If the rubber ring is
damaged, replace the thermostat.
(2) When assembling the thermostat, be careful not to fold
over or scratch the rubber ring.
BRADIATOR LOWER HOSE CONNECTION
(1) Insert each hose as far as the projection of the water
inlet fitting.
(2) Align the mating marks on the radiator hose and hose
clamp, and then connect the radiator hose.
INSPECTION
THERMOSTAT CHECK
(1) Immerse the thermostat in water, and heat the water while
stirring. Check the thermostat valve opening temperature.
Standard value: 76.5 ± 1.5
C
(2) Check that the amount of valve lift is at the standard
value when the water is at the full-opening temperature.
Standard value:
Full-opening temperature: 90
C
Amount of valve lift: 8.5 mm or more
NOTE
Measure the valve height when the thermostat is fully
closed, calculate the valve lift by subtracting this
measurement from the valve height when the thermostat
is fully open.

ON-VEHICLE SERVICE
1. TURBOCHARGER BOOST PRESSURE
CHECK
Caution
Carry out driving tests in a location where full-throttle
acceleration is possible with utmost safety. Two persons
should be in the vehicle during the test, the assistant
in the front passenger seat reading the pressure gauge.
(1) Disconnect the hose (black) from the boost pressure
control solenoid valve and fit the pressure gauge to this
hose.
After the hose (black) has been disconnected, fit a blank
plug to the solenoid valve nipple.
(2) Drive at full-throttle acceleration in second gear and
measure the boost pressure when the engine speed
exceeds about 3,000 r/min.
Standard value:
53 – 87 kPa {0.54 – 0.89 kg/cm

6. SECONDARY AIR CONTROL SYSTEM
CHECK
(1) Start the engine and let it run at idle speed.
(2) Short-circuit the no. 6 terminal of the engine ECU
connector using a jumper wire and check at this time
that the secondary air valve lifts.
At this time, the engine ECU connector should be
connected.

7-1 OPERATION CHECK
(1) Disconnect the vacuum hose (white stripe, yellow stripe)
from the solenoid valve.
(2) Disconnect the harness connector.
(3) Connect a hand vacuum pump to nipple A of the solenoid
valve.
(4) Using jumper wires, connect the solenoid valve terminal
to battery terminals.
(5) Disconnecting and reconnecting the jumper wire on the
(–) terminal side, apply vacuum to check for airtightness.

REMOVAL SERVICE POINT
ADELIVERY PIPE, INJECTOR AND PRESSURE
REGULATOR REMOVAL
Remove the delivery pipe with the injectors and pressure
regulator attached to it.
Caution
Care must be taken, when removing the delivery pipe,
not to drop the injector.
INSTALLATION SERVICE POINT
AHIGH-PRESSURE FUEL HOSE INSTALLATION
(1) When connecting the high-pressure fuel hose to the
delivery pipe, apply a small amount of new engine oil
to the O-ring and then insert the high-pressure fuel hose,
being careful not to damage the O-ring.
Caution
Be careful not to let any engine oil get into the delivery
pipe.
(2) Check to be sure that the high pressure hose turns
smoothly.
If it does not turn smoothly, the O-ring may be trapped.
Remove the high-pressure fuel hose to check for damaged
O-ring and then re-insert it into the delivery pipe and
check once again.
(3) Tighten the mounting bolts to the specification.
INSPECTION
INTAKE MANIFOLD CHECK
(1) Check the intake manifold for damage or cracking and
replace it if defective.
(2) Using a straight edge and feeler gauge, check for distortion
of the cylinder head installation surface.

INSPECTION
1. TURBOCHARGER CHECK
(1) Visually check the turbine wheel and compressor wheel
for damage and cracking.
(2) Check that the turbine wheel and compressor wheel can
be turned manually with a light force.
(3) Check that there is no oil leak from the turbocharger.
(4) Check to see if the wastegate valve remains open. If
any of these faulty symptoms is evident, disassemble
the turbocharger and replace the defective part.
NOTE
For the disassembly procedure, refer to ENGINE
WORKSHOP MANUAL.
2. EXHAUST MANIFOLD CHECK
(1) Check the exhaust manifold for damage and cracking
and replace it as necessary.
(2) Using a straightedge and feeler gauge, check the cylinder
head mounting surface for distortion and replace as
necessary.
