CO-36, "Changing Engine Coolant".
CAUTION:
• Perform this step when engine is cold.
• Never spill engine coolant on drive belt.
2. Remove battery and battery tray. Refer to SC-7, "
Removal and Installation".
3. Remove air cleaner and air duct. Refer to EM-135, "
Component".
4. Remove radiator hose (lower) from engine. Refer to CO-40, "
Component".
5. Remove heater hoses and water hoses.
6. Remove CVT warmer hose (CVT models only).
7. Remove water outlet.

• When connecting or disconnecting pin connectors into or
from TCM, take care not to damage pin terminals (bend or
break).
When connecting pin connectors make sure that there are not
any bends or breaks on TCM pin terminal.
• Before replacing TCM, perform TCM input/output signal
inspection and make sure whether TCM functions properly or
not. CVT-46, "
TCM Terminal and Reference Value".
• After performing each TROUBL E DIAGNOSIS, perform “DTC
Confirmation Procedure”.
If the repair is completed the DTC should not be displayed in
the “DTC Confirmation Procedure”.
• Always use the specified br and of CVT fluid. Refer to MA-14, "
Flu-
ids and Lubricants".
• Use lint-free paper, not cloth rags, during work.
• After replacing the CVT fluid, dispose of the waste oil using the methods prescribed by law, ordinance, etc.
Service Notice or PrecautionINFOID:0000000005928726
CVT FLUID COOLER SERVICE
If CVT fluid contains friction material (clutches, brakes , etc.), or if an CVT is replaced, inspect and clean the
CVT fluid cooler mounted in the radiator or replace the radiator. Flush cooler lines using cleaning solvent and
compressed air after repair. For CVT fluid cooler cleaning procedure, refer to CVT-15, "
CVT Fluid Cooler
Cleaning". For radiator replacement, refer to CO-40.
OBD-II SELF-DIAGNOSIS
• CVT self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through
the blinking pattern of the malfunction indi cator lamp (MIL). Refer to the table on CVT-48, "
CONSULT-III
Function (TRANSMISSION)" for the indicator used to display each self-diagnostic result.
• The self-diagnostic results indicated by the MIL are automatically stored in both the ECM and TCM memo- ries.
Always perform the procedure on CVT-27, "
OBD-II Diagnostic Trouble Code (DTC)" to complete the
repair and avoid unnecessary blinking of the MIL.
For details of OBD-II, refer to EC-541, "
Introduction".
• Certain systems and components, especially those re lated to OBD, may use the new style slide-lock-
ing type harness connector. For description and how to disconnect, refer to PG-65
.

If it is above 10°
C (50°F), the test result will be OK.
If it is below 10 °C (50° F), go to following step.
4. Start engine and run it for 65 minutes at idle speed. If “COOLAN TEMP/S” increases to more than 10° C (50°F) within 65 minutes, stop engine because
the test result will be OK.
