REMOVAL

WARNING:

Never remove radiator cap when engine is hot. Serious burns could occur from high-pressure engine
coolant escaping from radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter of a turn to
release built-up pressure. Carefully remove radiator cap by turning it all the way.
NOTE:
When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spill-
ing.
1.

Remove the following parts:
• Engine under cover.
• Radiator core support covers (RH and LH): Refer to 

EM-31, "Exploded View"

.

• Air duct (inlet): Refer to 

EM-31, "Exploded View"

.

• Front grille: Refer to 

EXT-21, "Exploded View"

.

• Horn: Refer to 

HRN-8, "Exploded View"

.

• Hood lock: Refer to 

DLK-338, "Exploded View"

.

2.

Drain engine coolant from radiator. Refer to 

CO-11, "Draining"

.

CAUTION:

• Perform this step when the engine is cold.
• Never spill engine coolant on drive belt.

3.

Disconnect reservoir tank hose from radiator pipe (upper).

4.

Disconnect CVT fluid cooler hoses from radiator.
• Install blind plug to avoid leakage of CVT fluid.

5.

Remove radiator cap adapter and each radiator hoses (upper) and radiator pipe (upper) assembly.

CAUTION:

Be careful not to allow engine coolant to contact drive belt.

6.

Disconnect radiator hose (lower) from radiator.

7.

Remove condenser. Refer to 

HA-50, "Exploded View"

.

CAUTION:

Be careful not to damage condenser core.

8.

Remove each radiator upper clips (2) by pulling the tabs (A) out-
side to release the lock (B) and then remove each mounting rub-
bers (upper) (1).

CAUTION:

Never pull the tabs outside excessively to prevent it from
damping.

9.

Lift up and remove radiator (1) from front of radiator core support
(2).

CAUTION:

RADIATOR

Note the following, and install in the reverse order of removal.

Radiator Upper Clip

Install each radiator upper clips on radiator core connection as follows:
1.

Install each mounting rubbers (upper) (1) on mounting pins (A)
of radiator.

2.

Align each radiator upper clips (2) with radiator core connection
(B), then insert each radiator upper clips straight into radiator
core connections until a click is heard.

3.

After connecting each radiator upper clips, use the following
method to check it is fully connected.
• Visually confirm that each radiator upper clips are connected

to radiator core connections.

• Move each radiator upper clips and the radiator forward and backward to check they are securely con-

nected.

Radiator hose

CAUTION:

• Use genuine mounting bolts for the cooling fan assembly and strictly observe the tightening torque.

(Breakage prevention for radiator)

NOTE:
• Insert the radiator hose (1) all the way to the stopper (2) or by 33 mm (1.30 in) (hose without a stopper).

• For the orientation of the hose clamp pawl, refer to the figure.

*Refer to the illustrations for the specific position each hose clamp tab.

within the reference value. 

Inspection

INFOID:0000000009720484

INSPECTION AFTER INSTALLATION

• Check for leakage of engine coolant using the radiator cap tester adapter (commercial service tool) and the

radiator cap tester (commercial service tool). Refer to 

CO-11, "Inspection"

.

• Start and warm up the engine. Visually check that there is no leakage of engine coolant and CVT fluid.
