(c) Connect terminals 2 and 3 on the wire harness side con-
nector through a 3.4 watts test bulb.
(d) Turn the ignition switch ON, check that the bulb comes on
and the receiver gauge needle moves towards the full
side.
HINT:
Because of silicon oil in the gauge, it will take a short time for
the needle to stabilize.
If operation is not as specified, inspect the receiver gauge resis-
tance.
4. INSPECT FUEL LEVEL WARNING LIGHT OPERATION
(a) Disconnect the connector from the sender gauge.
(b) Connect terminals 2 and 3 on the wire harness side con-
nector.
(c) Turn the ignition switch ON and check that the warning
light comes on.
If the warning light does not come on, test the bulb or inspect
the wire harness.
5. INSPECT ENGINE COOLANT TEMPERATURE SEND-
ER GAUGE RESISTANCE
(a) Disconnect the engine coolant temperature sender
gauge.
(b) Measure the resistance between terminals 1 and 2 of the
connector according to the value(s) in the table below.
Temperature °C (°F)Resistance (W)
±20 (±4)13,840 to 16,330
20 (68)2,320 to 2,590
80 (176)310 to 326
110 (230)139.9 to 143.5
If resistance value is not as specified, replace the engine cool-
ant sender gauge.
6. INSPECT OIL PRESSURE SENDER OPERATION
(a) Disconnect the connector from the oil pressure sender.
(b) Check that no continuity exists between terminal and
ground with the engine stopped.
(c) Check that continuity exists between terminal and ground
with the engine running.
HINT:
Oil pressure should be over 24.5 kPa (0.25 kgf/cm
2, 3.55 psi).
If operation is not as specified, replace the oil pressure sender.

REMOVAL
1. REMOVE COOLING UNIT (See page AC±26)
2. DRAIN ENGINE COOLANT FROM RADIATOR
HINT:
It is not necessary to drain out all the coolant.
3. DISCONNECT WATER VALVE CONTROL CABLE
FROM WATER VALVE (See page AC±79)
4. DISCONNECT WATER HOSES FROM HEATER RA-
DIATOR PIPES
(a) Using pliers, grip the claws of the clips and slide the clips
along the hose.
(b) Disconnect the water hoses.
(c) Remove the grommet.
HINT:
At the time of installation, refer to the following:

Push the water hose onto the heater radiator pipe up to
the second ridge on the pipe.

Install the hose clip to the position shown in the illustra-
tion.
5. REMOVE INSTRUMENT PANEL AND REINFORCE-
MENT (See page BO±89)
