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.

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.

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-35, "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 (CVT
models). Tool number : EG17650301 (J-33984-A)

CAUTION:
• When removing water pump assembly, be car eful not to get coolant on drive belt.
• Water pump cannot be disassembled and must be replaced as a unit.
• After installing the water pump, connect hose and clamp securely, then check for leaks. Repair as
necessary.
NOTE:
When removing components such as hoses, tubes/lines, etc. , cap or plug openings to prevent fluid from spill-
ing.
REMOVAL
1. Disconnect the negative battery terminal. Refer to PG-73, "Removal and Installation (Battery)".

4. Turn the crankshaft pulley approximately 20
° clockwise so that
the timing chain on the timing chain tensioner side is loose.
5. Apply engine oil to the oil feed hole and timing chain tensioner and install the timing chain tensioner.
6. Remove the stopper pin (A).
7. Install valve timing control cover (bank 1) and water pump cover.
a. Before installing, remove all traces of liquid gasket from mating surface of water pump cover and IVT cover using a scraper.
Also remove traces of liquid gasket from the mating surface of the front cover.
b. Apply a continuous bead of liquid gasket to mating surface of IVT cover and water pump cover. Use Gen-
uine RTV Silicone Sealant or equivalent. Refer to GI-21, "Recommended Chemical Products and
Sealants".
CAUTION:
• Installation should be done within 5 minutes afte r applying liquid gasket.
• Do not fill the engine with oil for at least 30 minutes after the co mponents are installed to allow
the sealant to cure.
8. Install water drain plug (A) and copper sealing washer (B). CAUTION:
Do not reuse copper sealing washers.
9. Installation of remaining components is in the reverse order of removal. • After installation, refill coolant and check for leaks. Refer to CO-36, "Changing Engine Coolant"
and CO-
35, "System Inspection".
CAUTION:
Do not spill coolant in en gine compartment. Use a sh op cloth to absorb coolant.
• After starting engine, let idle for three minutes, then rev engine up to 3,000 rpm under no load to purge air from the high-pressure chamber of the chai n tensioner. The engine may produce a rattling noise.
This indicates that air still remains in the chamber and is not a matter of concern.
INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-11, "FOR USA AND CANADA : Fluids and Lubricants"

WATER PUMP
• Use procedure below to check for fuel leakage.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak- age at connection points.
• Start engine. With engine speed increased, che ck again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration. NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oils/fluids including engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec-
ified level, if necessary.
