OPERATION l When the engine coolant temperature reaches approximately
85°C (185°F) in the ignition switch
“ON” position, the
therm0 sensor is turned on
to flow electricity through the radiator fan motor relay (coil) and the
therm0 sensor to the ground.
The radiator fan motor relay contact will be
closed.
l Then, electricity will flow through the radiator fan motor and the radiator fan motor relay
(contact) to the ground to rotate the radiator fan
motor.
NOTE
For models equipped with the air conditioning,
refer to GROUP
55-Troubleshooting for in-
formation concerning the operation of the con-
denser fan.

COOLING -Service Adjustment Procedures T210863
SERVICE ADJUSTMENT PROCEDUl$t&
ENGINE COOLANT LEAK CHECK
1. Loosen radiator cap.
2. Confirm that the engine coolant level is up to the filler
neck.
3. Install a radiator cap tester to the radiator filler neck and
apply 160
kPa (23 psi) pressure. Hold pressure for. two
minutes, while checking for leakage from the radiator, hose or connections.
Caution
Be sure to completely clean away any moisture from
the places checked. When the tester is removed, be careful not to spill anyengine coolant from it.
Be careful, when installing and removing the tester
and when testing, not to deform the filler neck of the
radiator.
4.If there is leakage, repair or replace the appropriate part.
RADIATOR CAP PRESSURE TEST
MlOFBAA
1.Use a special tool to attach the cap to the tester.
2.Increase the pressure until the indicator of the gage stops
moving.
Limit: 65
kPa (9.2 psi)
Standard value:
75- 105 kPa (1 1 - 15 psi)
3.Replace the radiator cap if the reading does not remain at
or above the limit.
NOTE
Be sure that the cap is clean before testing, since rust or
other foreign material on the cap seal will cause an im-
proper indication.
