4. INSPECT ENGINE COOLANT TEMPERATURE RE-
CEIVER GAUGE OPERATION
(a) Disconnect the connector from the sender gauge.
(b) Turn the ignition switch ON and check that the receiver
gauge needle indicates COOL.
(c) Ground terminal on the wire harness side connector
through a 3.4 W test bulb.
(d) Turn the ignition switch ON, and check that the bulb lights
up and the receiver gauge needle moves to the hot side.
If operation is as specified, replace the sender gauge.
Then recheck the system.
If operation is not as specified, measure the receiver gauge re-
sistance.
5. INSPECT LOW OIL PRESSURE WARNING LIGHT
(a) Disconnect the connector from the warning switch and
ground terminal on the wire harness side connector.
(b) Turn the ignition switch ON and check that the warning
light lights up.
If the warning light does not light up, test the bulb.

ON–VEHICLE INSPECTION
1. INSPECT CONDENSER FAN OPERATION
Inspect the fan operation, as shown in the chart below.
Test conditions:

Ignition switch ON

Blower speed control dial at ”HI” position

Temperature control dial at ”COOL” position

Set on manifold gauge set

A/C switch ON
ConditionFan operation (Fan speed)
Engine coolant temperature
91C (196F) or belowNot rotate
Engine coolant temperature
100C (212F) or aboveRotate
Refrigerant pressure is less than
1,520 kPa (15.5 kgf/cm2, 220 psi)Rotate (Low speed)
Refrigerant pressure is 1,520 kPa
(15.5 kgf/cm2, 220 psi) or aboveRotate (High speed)
If operation is not as specified, proceed to the next inspection.
2. INSPECT CONDENSER FAN MOTOR OPERATION
(a) Disconnect the connector.
(b) Connect the battery and ammeter to fan connector, as
shown in the illustration.
(c) Check that the fan rotates smoothly and then check that
the reading on the ammeter.
Specified amperage:
9.5
1.5 A at 20C (68F)

If operation is not as specified, replace the fan mo-
tor.

If operation is as specified, check the pressure
switch, cooling fan relays and water temp. switch.

INSPECTION
1. REMOVE ENGINE UNDER COVER
2. DRAIN ENGINE COOLANT
3. REMOVE WATER TEMPERATURE SWITCH
(a) Disconnect the connector.
(b) Remove the water temperature switch and O–ring.
4. INSPECT WATER TEMPERATURE SWITCH OPERA-
TION
(a) Using an ohmmeter, check that the no continuity exists
between terminals when the coolant temperature is
above 93C (199F).
If continuity exists, replace the switch.
(b) Using an ohmmeter, check that there is no continuity ex-
ists between the terminals when the coolant temperature
is below 83C (181F).
If no continuity exists, replace the switch.
5. REINSTALL WATER TEMPERATURE SWITCH
(a) Install a new O–ring to the water temperature switch.
(b) Install the water temperature switch.
(c) Connect the connector.
6. REINSTALL ENGINE UNDER COVER
7. FILL WITH ENGINE COOLANT
8. START ENGINE AND CHECK FOR COOLANT LEAK
