disconnect the hose.
INSTALLATION SERVICE POINTS
"AAO-RING INSTALLATION
Fit an O-ring into the groove of the water inlet pipe and
apply water to the circumference of the O-ring or the
inside of the mounting surface of the pipe for insertion.
CAUTION
Do not let the O-ring get contaminated with grease, such
as engine oil.
"BAWATER INLET PIPE INSTALLATION
After installing the water outlet fitting and the thermostat
case assembly, tighten the mounting bolt of the water
inlet pipe to the specified torque.
"CARADIATOR LOWER HOSE/RADIATOR UPPER
HOSE CONNECTION
1. Insert each hose as far as the projection of the water
inlet pipe or water outlet fitting.
2. Align the mating marks on the radiator hose and hose
clamp, and then connect the radiator hose.
INSPECTION
WATER PIPE AND HOSE CHECK
Check the water pipe and hose for cracks, damage, clog
and replace them if necessary.

INSTALLATION SERVICE POINTS
"AAFUEL HIGH-PRESSURE HOSE CONNECTION
1. Apply a drop of new engine oil to the O-ring.
Caution
Be sure not to let engine oil enter the delivery pipe.
2. While turning the injector, high-pressure fuel hose and
fuel pressure regulator to the right and left, install the
delivery pipe, while being careful not to damage the O-ring.
After installing, check that the hose turns smoothly.
3. If it does not turn smoothly, the O-ring may be trapped,
remove the injector, high-pressure fuel hose or fuel
pressure regulator and then re-insert it into the delivery
pipe and check once again.
4. Tighten the high-pressure fuel hose to the specified torque.
Tightening torque: 5.0±1.0 N⋅m
INSPECTION
Check the following points; replace the part if a problem is
found.
INTAKE MANIFOLD CHECK
1. Check for damage or cracking of any part.
2. Check for obstruction of the negative pressure (vacuum)
outlet port, and for obstruction of the water passage or
gas passage.
3. Using a straight edge and thickness gauge, check for
distortion of the cylinder head installation surface.

"CASNAP RING INSTALLATION
Lay the assembly with the compressor cover facing down
and fit the snap ring.
Caution
Fit the snap ring with its chamfered side facing up.
"DATURBINE HOUSING INSTALLATION
Install the turbine housing in relation to the dowel pin.
Caution
Use care not to damage the blades of turbine wheel.
"EACOUPLING INSTALLATION
Install the coupling and tighten to the specified torque.
"FAWASTE GATE ACTUATOR OPERATION CHECK
Using a tester, apply a pressure of approx. 100.0 kPa to
the actuator and make sure that the rod moves.
Caution
Do not apply a pressure of more than 113.3 kPa to the
actuator. Otherwise, diaphragm may be damaged. Never
attempt to adjust the waste gate valve.
INSPECTION
TURBINE HOUSING
1. Check the housing for traces of contact with the turbine
wheel, cracks due to overheating, pitching, deformation
and other damage. Replace with a new turbine housing
if cracked.
2. Operate the waste gate valve lever manually to check
that the gate can be operated and closed smoothly.

ENGINE ELECTRICAL -Ignition System16-26
IGNITION SYSTEM
GENERAL INFORMATION
This system is equipped with two ignition coils (A
and B) with built-in power transistors for the No.
1 and No. 4 cylinders and the No. 2 and No. 3
cylinders respectively.
Interruption of the primary current flowing in the
primary side of ignition coil A generates a high
voltage in the secondary side of ignition coil A.
The high voltage thus generated is applied to the
spark plugs of No. 1 and No. 4 cylinders to generate
sparks. At the time that the sparks are generated
at both spark plugs, if one cylinder is at the
compression stroke, the other cylinder is at the
exhaust stroke, so that ignition of the compressed
air/fuel mixture occurs only for the cylinder which
is at the compression stroke.
In the same way, when the primary current flowing
in ignition coil B is interrupted, the high voltage
thus generated is applied to the spark plugs of
No. 2 and No. 3 cylinders.
The Engine-ECU turns the two power transistors
inside the ignition coils alternately on and off. Thiscauses the primary currents in the ignition coils
to be alternately interrupted and allowed to flow
to fire the cylinders in the order 1-3-4-2.
The Engine-ECU determines which ignition coil
should be controlled by means of the signals from
the camshaft position sensor which is incorporated
in the camshaft and from the crank angle sensor
which is incorporated in the crankshaft. It also
detects the crankshaft position in order to provide
ignition at the most appropriate timing in response
to the engine operation conditions. It also detects
the crankshaft position in order to provide ignition
at the most appropriate timing in response to the
engine operation conditions.
When the engine is cold or operated at high
altitudes, the ignition timing is slightly advanced
to provide optimum performance.
When the automatic transmission shifts gears, the
ignition timing is also retarded in order to reduce
output torque, thereby alleviating shifting shocks.

EGR VALVE CHECK
1. Remove the EGR valve and inspect for sticking, carbon
deposits, etc. If found, clean with a suitable solvent so
that the valve seats correctly.
2. Connect a hand vacuum pump to the EGR valve.
3. Apply 67 kPa of vacuum, and check that the vacuum
is maintained.
4. Apply a vacuum and check the passage of air by blowing
through one side of the EGR passage.
VacuumPassage of air

EGR PORT VACUUM CHECK
1. Disconnect the vacuum hose (White stripe) from the
throttle body EGR vacuum nipple and connect a hand
vacuum pump to the nipple.
2. Start the engine and check vacuum remains fairly constant
after racing the engine.
NOTE
If the vacuum fluctuates, the throttle body EGR port may
be clogged and need cleaning.
