5. Connect the special tool (MB991658) to the harness side
of the engine coolant temperature sensor connector.
6. Connect the special tool [MB991791(APS)] to the special
tool (MB991658).
7. Start the engine and let it run at idle.
NOTE
Since the resistance value of the special tool (APS)
indicates a low engine coolant temperature, engine speed
increases.
8. When the lever of the special tool (APS) is turned to
the end, check that the engine speed decreases and
the radiator fan motor rotates.
9. When the lever of the special tool (APS) is turned to
the reverse direction, check that the voltage between
terminals of the radiator fan motor connector gradually
decreases from the battery voltage to 0 V.
10. If inoperable, replace the radiator fan controller.
(Refer to P.14-15.)
11. Install the center under cover.
(Refer to GROUP 51 - Front Bumper.)
12. Connect the engine coolant temperature sensor
connector.

1. Remove the center under cover.
(Refer to GROUP 51 - Front Bumper.)
2. Insert the special tool at the back of the radiator fan
motor connector.
3. Connect the special tool to the circuit tester.
4. Start the engine and run it at idle.
5. Turn the A/C switch to the ON position and hold the
engine coolant temperature at 80_C or lower.
6. When the voltage between the terminals of the radiator
fan motor connector, the following values of (1) - (3)
can be detected at random.
(1) 0 V
(2) 8.22.6 V
(3) Battery voltage2.6 V
7. If inoperable, replace the radiator fan controller.
(Refer to P.14-15.)
8. Install the center under cover.

RADIATOR FAN MOTOR CHECK
1. Remove the center under cover.
(Refer to GROUP 51 - Front Bumper.)
2. Disconnect the radiator fan motor connector.
3. Check that the motor rotates when energizing battery
voltage between the terminals of connectors of the radiator
fan motor side.Check that there is abonormal noise from
the radiator fan motor then.
4. If inoperable, replace the radiator fan motor.
(Refer to P.14-15.)

HOSE DISCONNECTION
After making mating marks on the hose and the hose clamp,
disconnect the hose.
INSTALLATION SERVICE POINTS
"AAO-RING INSTALLATION
Fit an O-ring into the groove of the water inlet pipe and
apply water to the circumference of the O-ring or the
inside of the mounting surface of the pipe for insertion.
CAUTION
Do not let the O-ring get contaminated with grease, such
as engine oil.
"BAWATER INLET PIPE INSTALLATION
After installing the water outlet fitting and the thermostat
case assembly, tighten the mounting bolt of the water
inlet pipe to the specified torque.
"CARADIATOR LOWER HOSE/RADIATOR UPPER
HOSE CONNECTION
1. Insert each hose as far as the projection of the water
inlet pipe or water outlet fitting.
2. Align the mating marks on the radiator hose and hose
clamp, and then connect the radiator hose.
