Refer to GI-11, "Components" for symbol marks in the figure.
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.

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.

The following symptoms are not malfunctions.
Fuel gauge
Depending on vehicle posture or driving circumstance, the fuel level in the tank varies, and the pointer
may fluctuate.
If the vehicle is fueled with the ignition switch ON, the pointer will move slowly.
Low-fuel warning lamp
Depending on vehicle posture or driving circumstance, the fuel in the tank flows and the warning lamp ON
timing may change.
Water temperature gauge pointer Reference value of data monitor [ °C ( °F)]
Hot Approx. 130 (266)
Middle Approx. 70 - 105 (158 - 221) Cold Approx. 50 (122)

UNIFIED METER AND A/C AMPPFP:27760
System DescriptionNKS00300
For the unified meter and A/C amp., the signal required for controlling the combination meter are inte-
grated in the A/C auto amp.
The unified meter and A/C amp. corresponds to a CONSULT-II function (self-diagnosis results, CAN diag-
nosis support monitor, data monitor).
COMBINATION METER CONTROL FUNCTION
Unified meter and A/C amp. receives necessary information for combination meter from each unit by CAN
communication.
Unified meter and A/C amp. transmits a signals with communication line (TX, RX) between unified meter
and A/C amp. and combination meter.
Input/output signals between unified meter and A/C amp. and combination meter.
NOTE:
Combination meter performs fail-safe operation when unified meter and A/C amp. communication is malfunctioning. Refer to DI-8,
