Removal and InstallationNFS000O6
REMOVAL
1. Disconnect ABS actuator and electric unit (control unit) connector.
2. Loosen brake tube flare nuts, then remove brake tubes from ABS actuator and electric unit (control unit).
3. Remove LH side fender protector. Refer to EI-24, "
FENDER PROTECTOR" .
4. Remove ABS actuator and electric unit (control unit) mounting nuts.
5. Remove ABS actuator and electric unit (control unit) from vehicle.
CAUTION:
Be careful of the following when removing ABS actuator and electric unit (control unit).

If the part number on the part number label (pasted on actuator upper surface) is the same, ABS
actuator and electric unit (control unit) can not be used on another vehicle.
If it is used on another vehicle, ABS warning lamp, SLIP indicator lamp and VDC OFF indicator
lamp may turn ON or VDC/TCS/ABS may not operate normally.
When replacing ABS actuator and electric unit (control unit), must use new service parts.

Before servicing, disconnect battery cables.

To remove brake tube, use a flare nut torque wrench to prevent flare nuts and brake tube from
being damaged. To install, use a flare nut torque wrench (commercial service tool) and tighten to
the specified torque.

Do not apply excessive impact to actuator, such as dropping it.

Do not remove and install ABS actuator and electric unit (control unit) by holding harness.

INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
Be careful of the following when installing ABS actuator and electric unit (control unit).

Tighten the mounting bolts and nuts to the specified torque.

After the work, bleed air from brake piping. Refer to BR-10, "Bleeding Brake System" .

After installing vehicle harness connector in the actuator, make sure connector is securely locked.

When replacing ABS actuator and electric unit (control unit), calibrate steering angle sensor neu-
tral position and decel G sensor. Refer to BRC-6, "
ON-VEHICLE SERVICE" .

Removal and InstallationNFS000O7
REMOVAL
1. Remove center console. Refer to IP-12, "(H) Center Console" .
2. Disconnect G sensor harness connector.
3. Remove G sensor mounting bolts. Then remove G sensor from vehicle.
CAUTION:

Do not drop or strike G sensor, because it has little endur-
ance to impact.

Do not use power tool etc., because G sensor is weak for
the impact.
INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:

Do not drop or strike G sensor, because it has little endurance to impact.

After performing above works, calibrate decel G sensor (AWD models). Refer to BRC-7, "Calibra-
tion of Decel G Sensor (AWD Models)" .

WATER INLET AND THERMOSTAT ASSEMBLY
Revision: 2006 July 2007 FX35/FX45
INSPECTION AFTER REMOVAL
1. Check valve seating condition at ordinary room temperatures. It should seat tightly.
2. Check valve operation.

If the malfunctioning condition, when valve seating at ordinary
room temperature, or measured values are out of the standard,
replace water inlet and thermostat assembly.
INSTALLATION
Note the following, and install in the reverse order of removal.

Be careful not to spill engine coolant over engine room. Use rag to absorb engine coolant.
INSPECTION AFTER INSTALLATION

Check for leaks of engine coolant using the radiator cap tester adapter [SST: EG17650301 (J33984-A)]
and the radiator cap tester (commercial service tool). Refer to CO-11, "
LEAK CHECK" .

Start and warm up the engine. Visually make sure that there is no leaks of engine coolant.

Removal and InstallationNBS003KS
REMOVAL
1. Drain engine coolant from drain plugs on radiator and both side of cylinder block. Refer to CO-38, "Chang-
ing Engine Coolant" and EM-249, "DISASSEMBLY" .
CAUTION:

Perform this step when engine is cold.

Do not spill engine coolant on drive belts.
2. Remove engine cover with power tool. Refer to EM-173, "
ENGINE ROOM COVER" .
3. Remove air duct (inlet). Refer to EM-177, "
AIR CLEANER AND AIR DUCT" .
4. Disconnect water suction hose from water inlet.
5. Remove water inlet and thermostat. CAUTION:
Do not disassemble thermostat.
6. Remove intake manifolds (upper and lower). Refer to EM-179, "
INTAKE MANIFOLD" .
7. Disconnect radiator hose (upper) and water hoses from thermostat housing.
8. Disconnect heater hoses from water outlet and heater pipe.
9. Remove thermostat housing, water outlet pipe, water connector, water control valve, water outlet and heater pipe.
CAUTION:
Do not disassemble water control valve.
INSPECTION AFTER REMOVAL

Make sure that valves both in thermostat and water control valve are completely closing at normal temper-
ature.

Place a thread so that it is caught in the valves of the thermostat
and water control valve. Immerse fully in a container filled with
water. Heat while stirring. (The example in the figure shows ther-
mostat.)

The valve opening temperature is the temperature at which the
valve opens and falls from the thread.

Continue heating. Check the maximum valve lift.
NOTE:
The maximum valve lift standard temperature for water control
valve is the reference value.

After checking the maximum valve lift, lower the water tempera-
ture and check the valve closing temperature.
Standard values:

If the malfunctioning condition, when closing valve at normal temperature, or measured values are out of
the standard, replace thermostat and/or water control valve.
INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
Be careful not to spill engine coolant over engine room. Use rag to absorb engine coolant.

COMBINATION METERS
Revision: 2006 July 2007 FX35/FX45
SPEEDOMETER
The speedometer indicates the vehicle speed.

ABS actuator and electric unit (control unit) provides a vehicle speed signal to the unified meter and A/C
amp. with CAN communication.

Unified meter and A/C amp. converts the vehicle speed signal to the 8-pulse signal, and outputs the vehi-
cle speed signal (8-pulse) to combination meter.

Combination meter indicates the vehicle speed according to vehicle speed signal (8-pulse) signal.
TACHOMETER
The tachometer indicates engine speed in revolutions per minute (rpm).

ECM provides engine speed signal to unified meter and A/C amp. with CAN communication.

Unified meter and A/C amp. transmits engine speed signal to combination meter with communication line.

Combination meter indicates the engine speed according to engine speed signal.
WATER TEMPERATURE GAUGE
The water temperature gauge indicates the engine coolant temperature.

ECM provides engine coolant temperature signal to unified meter and A/C amp. with CAN communica-
tion.

Unified meter and A/C amp. transmits engine coolant temperature signal to combination meter with com-
munication line.

Combination meter indicates the engine coolant temperature according to engine coolant temperature
signal.
