(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.
10. INSPECT ENGINE COOLANT TEMPERATURE RE-
CEIVER GAUGE RESISTANCE
Measure the resistance between terminals.
Tester connectionResistance (W) *
A ± BApprox. 175.7
A ± CApprox. 54.0
B ± CApprox. 229.7
*: This circuit includes the diode.
HINT:
Connect the test leads so that the current from the ohmmeter
can flow according to the above order.
If resistance value is not as specified, replace the receiver
gauge.
11. INSPECT ENGINE COOLANT TEMPERATURE SEND-
ER GAUGE RESISTANCE
Measure the resistance between the terminal and gauge body.
Temperature °C (°F)Resistance (W)
50 (122.0)274
120 (248.0)26.4
If resistance value is not as specified, replace the engine cool-
ant temperature sender gauge.
12. 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.

13. INSPECT LOW OIL PRESSURE SWITCH
(a) Disconnect the connector from the switch.
(b) Check that continuity exists between terminal and ground
with the engine stopped.
(c) Check that no 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 switch.
14. INSPECT BRAKE SYSTEM WARNING LIGHT
(a) Disconnect the connector from the brake fluid warning
switch.
(b) Release the parking brake pedal.
(c) Connect the terminals on the wire harness side of the lev-
el warning switch connector.
(d) Start the engine, check that the warning light lights up.
If the warning light does not light up, test the bulb or wire har-
ness.
15. INSPECT BRAKE FLUID LEVEL WARNING SWITCH
(a) Remove the reservoir tank cap and strainer.
(b) Disconnect the connector.
(c) Check that no continuity exists between the terminals with
the switch OFF (float up).
(d) Use syphon, etc. to take fluid out of the reservoir tank.
(e) Check that continuity exists between the terminals with
the switch ON (float down).
(f) Pour the fluid back in the reservoir tank.
If operation is not as specified, replace the switch.
16. INSPECT PARKING BRAKE SWITCH
(a) Check that continuity exists between the terminal and
switch body with the switch ON (switch pin released).
(b) Check that no continuity exists between the terminal and
switch body with the switch OFF (switch pin pushed in).
If operation is not as specified, replace the switch or inspect
ground point.
17. INSPECT WASHER FLUID LEVEL WARNING LIGHT
(a) Disconnect the connectors from the level warning switch
and parking brake switch.
(b) Connect terminals on the wire harness side connector of
the level warning switch connector.
(c) Remove the GAUGE fuse and turn the ignition switch ON,
and check that the warning light comes on.
If the warning light does not light up, test the bulb.

(b) Check the lock plate height (H) after completing the caulk-
ing.
Plate height: 7.40 ± 7.80 mm (0.2913 ± 0.3071 in.)
If not within the specified height, adjust the stopper bolt of the
handle again and caulk again.
6. INSTALL ECT SWITCH
(a) Install a new O±ring to the ECT switch.
(b) Install the ECT switch.
7. INSTALL DRAIN PLUG
(a) Install a new O±ring to the drain plug.
(b) Install the drain plug.
8. INSPECT FOR WATER LEAKS
(a) Plug the inlet and outlet pipes of the radiator with SST.
SST 09230±01010
(b) Using a radiator cap tester, apply pressure to the radiator.
Test pressure: 177 kPa (1.8 kgf/cm
2, 26 psi)
(c) Submerge the radiator in water.
(d) Inspect for leaks.
HINT:
On radiators with resin tanks, there is a clearance between the
tank and lock plate where a minute amount of air will remain,
giving the appearance of an air leak when the radiator is sub-
merged in water. Therefore, before doing the water leak test,
first swish the radiator around in the water until all air bubbles
disappear.
