RADIATOR CAP : Inspection

INFOID:0000000003793170

• Check valve seat (A) of radiator cap. 
- Check if valve seat is swollen to the extent that the edge of the

plunger (B) cannot be seen when watching it vertically from the
top.

- Check if valve seat has no soil and damage.
- Check that there is no dirt or damage on the valve seat of radiator

cap negative-pressure valve. 

- Check that there are no unusualness in the opening and closing

conditions of negative-pressure valve.

• Check radiator cap relief pressure.

- When connecting radiator cap to the radiator cap tester (commer-

cial service tool) and the radiator cap tester adapter (commercial
service tool) (A), apply engine coolant to the cap seal surface. 

• Replace radiator cap if there is an unusualness related to the above three.

CAUTION:

When installing radiator cap, thoroughly wipe out the radiator pipe (upper) filler neck to remove any
waxy residue or foreign material.

RADIATOR : Inspection

INFOID:0000000003793171

Check radiator for mud or clogging. If necessary, clean radiator as follows:

CAUTION:

• Be careful not to bend or damage radiator fins.
• When radiator is cleaned without removal, remove all surrounding parts such as radiator cooling fan

assembly and horns. Then tape harness and connectors to prevent water from entering.

1.

Apply water by hose to the back side of the radiator core vertically downward.

2.

Apply water again to all radiator core surfaces once per minute.

3.

Stop washing if any stains no longer flow out from radiator.

4.

Blow air into the back side of radiator core vertically downward.
• Use compressed air lower than 490 kPa (4.9 bar, 5 kg/cm

2

, 71 psi) and keep distance more than 30 cm

(11.81 in). 

5.

Blow air again into all the radiator core surfaces once per minute until no water sprays out.

RADIATOR

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.

1.

Remove the following parts:
• Engine under cover.
• Air duct (inlet): Refer to 

EM-26, "Exploded View"

.

• Horn: Refer to 

HRN-6, "Exploded View"

.

• Hood lock: Refer to 

DLK-220, "Exploded View"

.

2.

Drain engine coolant from radiator. Refer to 

CO-8, "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.

Disconnect Low-pressure flexible hose from lower pressure pipe, and then move it to aside. Refer to 

HA-

38, "Exploded View"

.

6.

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

CAUTION:

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

7.

Disconnect radiator hose (lower) from radiator.

8.

Remove condenser. Refer to 

HA-46, "Exploded View"

.

CAUTION:

Be careful not to damage condenser core.

9.

Remove radiator upper clip (2) by pulling the tabs (A) outside to
release the lock (B) and then remove mounting rubbers (upper)
(1).

CAUTION:

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

10. Lift up and remove radiator from front of radiator core support.

CAUTION:

Be careful not to damage or scratch on radiator core.

INSTALLATION

Note the following, and installation is the reverse order of removal.

Radiator Upper Clip

Install radiator upper clip on radiator core connection as follows:

1.

Install mounting rubbers (upper) (1) on mounting pins (A) of radi-
ator.

2.

Align radiator upper clip (2) with radiator core connection (B),
then insert radiator upper clip straight into radiator core connec-
tions until a click is heard.

3.

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

radiator core connections.

• Move radiator upper clip and the radiator forward and backward to check they are securely connected.

Inspection

INFOID:0000000003793174

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-8, "Inspection"

.

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