●Use pliers in the locations where Tool cannot be used.
5. Make sure that the rim is completely crimped down.
6. Confirm that there is no leakage.
Refer to CO-17, "
INSPECTION" .
INSPECTION
1. Apply pressure with Tool.
WARNING:
To prevent the risk of the hose coming undone while under
pressure, securely fasten it down with a hose clamp.
Attach a hose to the oil cooler to seal its inlet and outlet.
(A/T model only)
2. Check for leakage by soaking radiator in water container.

●Grip the crimped edge and bend it upwards so that Tool slips
off.
Do not bend excessively.
●In areas where Tool cannot be used, use a screwdriver to
bend the edge up.
Be careful not to damage tank.
2. Remove sealing rubber.
3. Make sure the edge stands straight up.
4. Remove oil cooler from tank. (A/T model only)
ASSEMBLY
1. Install oil cooler. (A/T model only)
Pay attention to direction of conical washer.

PRECAUTIONS
●Do not disassemble ECM.
●If a battery terminal is disconnected, the memory will return
to the ECM value.
The ECM will now start to self-control at its initial value.
Engine operation can vary slightly when the terminal is dis-
connected. However, this is not an indication of a malfunc-
tion. Do not replace parts because of a slight variation.
●When connecting ECM harness connector, fasten it
securely with a lever as far as it will go as shown at right.
●When connecting or disconnecting pin connectors into or
from ECM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on ECM
pin terminal, when connecting pin connectors.
●Securely connect ECM harness connectors.
A poor connection can cause an extremely high (surge)
voltage to develop in coil and condenser, thus resulting in
damage to ICs.
●Keep engine control system harness at least 10 cm (4 in)
away from adjacent harness, to prevent engine control sys-
tem malfunctions due to receiving external noise, degraded
operation of ICs, etc.
●Keep engine control system parts and harness dry.
●Before replacing ECM, perform “ECM Terminals and Refer-
ence Value” inspection and make sure ECM functions prop-
erly. Refer to EC-819
.
●Handle mass air flow sensor carefully to avoid damage.
●Do not disassemble mass air flow sensor.
●Do not clean mass air flow sensor with any type of deter-
gent.
●Do not disassemble electric throttle control actuator.
●Even a slight leak in the air intake system can cause seri-
ous incidents.
●Do not shock or jar the camshaft position sensor (PHASE),
crankshaft position sensor (POS).

5. CHECK IGNITION SPARK
1. Disconnect ignition coil assembly from rocker cover.
2. Connect a known-good spark plug to the ignition coil assembly.
3. Place end of spark plug against a suitable ground and crank engine.
4. Check for spark.
OK or NG
OK >> GO TO 6.
NG >> Check ignition coil, power transistor and their circuits.
Refer to EC-379, "
IGNITION SIGNAL" .
6. CHECK SPARK PLUGS
Remove the spark plugs and check for fouling, etc.
OK or NG
OK >> GO TO 7.
NG >> Repair or replace spark plug(s) with standard type
one(s). For spark plug type, refer to MA-24, "
Checking
and Changing Spark Plugs" .
7. CHECK COMPRESSION PRESSURE
Check compression pressure. Refer to EM-59, "
CHECKING COMPRESSION PRESSURE" .
OK or NG
OK >> GO TO 8.
NG >> Check pistons, piston rings, valves, valve seats and cylinder head gaskets.
8. CHECK FUEL PRESSURE
1. Install all removed parts.
2. Release fuel pressure to zero. Refer to EC-42, "
FUEL PRESSURE RELEASE" .
3. Install fuel pressure gauge and check fuel pressure. Refer to EC-42, "
FUEL PRESSURE CHECK" .
OK or NG
OK >> GO TO 9.
NG >> Follow the Instruction of “FUEL PRESSURE CHECK”.

IDLE SPEED
With CONSULT-II
Check idle speed in “DATA MONITOR” mode with CONSULT-II.
Without CONSULT-II
Check the idle speed by installing the pulse type tachometer clamp on the loop wire or on suitable high-tension
wire which installed between No.1 ignition coil and No.1 spark plug.
NOTE:
For the method of installing the tachometer, EC-448, "
IGNITION TIMING" .
IGNITION TIMING
Any of following two methods may be used.
●Method A
–Attach timing light to loop wire as shown.
–Check ignition timing.
●Method B
–Remove No. 1 ignition coil.
