NO: Replace the radiator fan motor. Then go to Step 7.
STEP 7. Check the symptoms.
Q: Do the radiator fan and condenser fan operate correctly?
YES: The procedure is complete.
NO: Return to Step 1 .
INSPECTION PROCEDURE 5: Radiator Fan does not Operate TECHNICAL DESCRIPTION The cause could be a malfunction of the radiator fan motor or an open circuit
between the fan control module and the radiator fan motor. TROUBLESHOOTING HINTS Malfunction of radiator fan motor DIAGNOSIS Replace the radiator fan motor. INSPECTION PROCEDURE 6: Condenser Fan does not Operate Radiator Fan and Condenser Fan Drive Circuit Refer to INSPECTION PROCEDURE 3: RADIATOR FAN AND CONDENSER FAN DO NOT OPERATE
.
CIRCUIT OPERATION
The fan control module is powered from fusible link number 2. The PCM judges the required revolution speed of radiator fan motor and
condenser fan motor using the input signals transmitted from A/C switch,
automatic compressor controller, vehicle speed sensor and engine coolant
temperature sensor. The PCM activates the fan control module to drive the
radiator fan motor and condenser fan motor.

6. Securely tighten the radiator drain plug.
7. Assemble the radiator condenser tank assembly.
8. By referring to the section on coolant, select an appropriate concentration for
safe operating temperature within the range of 30 to 60 %. Use MB991871 to
refill the coolant. A convenient mixture is a 50 % water and 50 % antifreeze
solution [freezing point: -31°C (-32.8 °F)].

CAUTION: Do not use alcohol or methanol anti-freeze or any
engine coolants mixed with alcohol or methanol
anti-freeze. The use of an improper anti-freeze
can cause corrosion of the aluminum
components.

ENGINE OIL REPLACEMENT 1. Start the engine and allow it to warm up until the temperature of the coolant
reaches 80 - 90°C (176 - 194°F).
2. Remove the engine oil filler cap.
3. Remove the drain plug to drain oil.
4. Install a new drain plug gasket so that it faces in the direction shown in the
illustration, and then tighten the drain plug to the specified torque.
Tightening torque: 39 +/- 5 N.m (29 +/- 3 ft-lb)
WARNING:Use care as oil could be hot.
