1. Fill the radiator from the filler neck above the r
adiator upper hose and reservoir tank with clean water and
reinstall the radiator filler cap.
2. Run the engine until it reaches normal operating temperature.
3. Rev the engine two or three times under no-load.
4. Stop the engine and wait until it cools down.
5. Drain the water from the system. Refer to CO-12, "Changing Engine Coolant"
.
6. Repeat steps 1 through 5 until clear water begins to drain from the radiator.

WARNING:
Do not remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure
engine coolant escaping from the radiator. Wrap a th ick cloth around the cap. Slowly push down and
turn it a quarter turn to allow built-up pressure to escape. Carefully remove the cap by pushing it down
and turning it all the way.
NOTE:
When removing components such as hoses, tubes/lines, etc. , cap or plug openings to prevent fluid from spill-

REMOVAL
1. Remove radiator cap and drain coolant from radiator. Refer to
CO-12, "Changing Engine Coolant".
CAUTION:
• Perform this step when the engine is cold.
• Do not spill coolant on the drive belt.
2. Remove front air duct. Refer to EM-84, "Removal and Installation"
.
3. Disconnect coolant reservoir hose from the radiator.
4. Remove fender protector side cover (LH/RH). Refer to EXT-26, "FENDER PROTECTOR : Exploded
View".
5. Disconnect radiator hose (upper) and radiat or hose (lower) from the radiator.
CAUTION:
Do not allow the coolant to contact the drive belt.
NOTE:
The radiator hose clamps on the radiator hose (upper ) and on the radiator hose (lower), are not serviced
separately. Radiator hose clamps are part of the radiator hose assembly and serviced as one unit with the
radiator hose.
6. Disconnect the CVT oil cooler hoses.
7. Remove the front bumper fascia. Refer to EXT-17, "Removal and Installation"
.
8. Remove A/C condenser. Refer to HA-30, "COMPRESSOR : Removal and Installation"
.
CAUTION:
Be careful not to damage condenser core.
9. Remove the radiator mounts (upper).
10. Remove radiator. CAUTION:
Do not damage or scratch the radiator core when removing.
INSTALLATION
Installation is in the reverse order of removal.
• After installation, refill coolant and check for leaks. Refer to CO-12, "Changing Engine Coolant"
and CO-11,
"System Inspection".
CAUTION:
Do not spill coolant in engi ne compartment. Use a shop cloth to absorb coolant.
InspectionINFOID:0000000009460394
INSPECTION AFTER INSTALLATION
• Check that the reservoir tank cap is tightened.
• Check for leakage of engine coolant using Tool (B) and suitable tool (A). Refer to CO-11, "System Inspection"
.
WARNING:
Do not remove the radiator cap wh en the engine is hot. Seri-
ous burns could occur from high pressure coolant escaping
from the radiator.
CAUTION:
Higher pressure than specified may cause radiator damage.
• Start and warm up the engine. Visually check that there is no leakage of engine coolant and CVT fluid.
Tool number : EG17650301 (J-33984-A)
