07)] (A) as shown.

• When connecting the reservoir tank cap to the reservoir tank cap

tester, apply water or LLC to the reservoir tank cap seal part.

• Check reservoir tank cap relief pressure.

• Replace the reservoir tank cap if the engine coolant passes

through it, or if any fur signs is detected.

CAUTION:

When installing reservoir tank cap, thoroughly wipe out the res-
ervoir tank filler neck to remove any waxy residue or foreign

assembly and horns. Then tape harness and harness 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

REMOVAL

WARNING:

• Never remove reservoir tank cap when engine is hot. Serious burns may occur from high-pressure

engine coolant escaping from radiator. 

• Wrap a thick cloth around the reservoir tank cap. Slowly turn it a quarter of a turn to release built-up

pressure. Then turn it all the way.

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.

2.

Remove front bumper. Refer to

6.

Remove radiator hose (upper and lower).

7.

Disconnect harness connectors from cooling fan, and move harness aside.

8.

Remove radiator and cooling fan assembly.

CAUTION:

Be careful not to damage radiator core and condenser  core.

NOTE:
In case of lower pin radiator is damaged, it can be repaired instead of replacing the radiator.

9.

Separate radiator from condenser.

INSTALLATION

Install in the reverse order of removal.
