Radiator: Service and Repair

Radiator

^ Radiator





^ Radiator fan





REMOVAL

CAUTION:
The radiator is pressurized when the engine and radiator are hot. Wait until engine and radiator cools down before working on the radiator.

1) Remove the collector cover.

NOTE:
Follow the steps below when removing the collector cover.

1) Lift up (A) in two positions at the rear.
2) Moving (B) in two positions at the front toward the vehicle, lift them up.





2) Disconnect the ground cable from battery.
3) Lift up the vehicle.
4) Remove the under cover.
5) Drain engine coolant completely.
6) Disconnect the integrated connector of radiator main fan & fan motor and radiator sub fan & fan motor.





7) Disconnect the radiator lower hose from the radiator lower.





8) Lower the vehicle.
9) Remove the air intake duct.
10) Remove the grille bracket.

NOTE:
Remove ten clips when removing the grille bracket.





11) Remove the radiator main fan & fan motor and radiator sub fan & fan motor.
12) Disconnect the ATF hoses A and B from the radiator.

NOTE:
Plug the ATF hoses A and B to prevent ATF from leaking.





13) Remove the radiator upper brackets.





14) Lift the radiator up and away from vehicle.
15) Remove the radiator lower cushion.

INSTALLATION
1) Install the radiator lower cushion.
2) Install the radiator to vehicle.

NOTE:
Insert pins on the lower side of radiator into the radiator lower cushions on vehicle side.

3) Install the radiator upper brackets.





4) Connect the ATF hoses A and B.

NOTE:
Use a new ATF hose.





5) Attach the grille bracket.





6) Install the radiator main fan & fan motor and radiator sub fan & fan motor.
7) Lift up the vehicle.
8) Connect the radiator lower hose to the radiator lower.





9) Connect the integrated connector of radiator main fan & fan motor and radiator sub fan & fan motor.





10) Install the under cover.
11) Lower the vehicle.
12) Connect the ground cable to battery.
13) Fill engine coolant.
14) Check the ATF level and replenish it if necessary.
15) Install the air intake duct.
16) Install the collector cover.

INSPECTION
1) Check that the radiator does not have deformation, cracks or damage.
2) Check that the hose has no cracks, damage or loose part.
3) Remove the radiator cap, fill the radiator with engine coolant, and then install the radiator cap tester to the filler neck of radiator.
4) Apply a pressure of 157 kPa (1.6 kgf/cm2, 23 psi) to the radiator, and check the following items.
^ Leakage from the radiator or its vicinity
^ Leakage from the hose or its connections

CAUTION:
^ Engine should be turned off.
^ Wipe engine coolant from checkpoints in advance.
^ Be careful of engine coolant from spurting out when removing the radiator cap tester.
^ Be careful not to deform the filler neck of radiator when installing and removing the radiator cap tester.

Radiator Cap

INSPECTION
1) Check that the radiator cap does not have deformation, cracks or damage.
2) Attach the radiator cap tester to radiator cap.





3) Increase pressure until the radiator cap tester gauge needle stops. Radiator cap is functioning properly if it holds the service limit pressure for 5 - 6 seconds. Replace the radiator cap if its valve opens at less than the service limit.

Standard:
93 - 123 kPa (0.95 - 1.25 kgf/cm2, 14 - 18 psi)

Service limit:
83 kPa (0.85 kgf/cm2, 12 psi)

CAUTION:
Be sure to remove foreign matter and rust from the cap in advance. Otherwise, results of pressure test will be incorrect.
