1. |
1. Disconnect the battery negative
terminal. |
2. |
Remove the air cleaner assembly. (Refer to
Intake and exhaust system in this
group) |
3. |
3. Remove the under cover (A).
Tightening torque:
19.6 ~ 24.5 N.m (2.0 ~ 2.5 kgf.m, 14.5 ~
18.1 lb-ft)
|

|
4. |
Loosen the drain plug (A), and drain the
coolant.
Remove the radiator cap to speed
draining.

Never remove the radiator cap when the
engine is hot. Serious scalding could be caused by hot fluid
under high pressure escaping from the
radiator. | |
5. |
Remove the radiator upper hose (A) and lower
hose (B).

|
6. |
Disconnect the ATF cooler hoses (A/T only).
(Refer to AT group) |
7. |
Disconnect the fan motor connector (A) and
then remove the cooling fan assembly.
Tightening
torque:
8.8 ~ 10.8 N.m (0.9 ~ 1.1 kgf.m, 6.5 ~
7.9 lb-ft)
|

|
8. |
Remove the front bumper. (Refer to BD
group) |
9. |
Disconnect the over flow hose (A) from the
radiator.

|
10. |
Remove the cover (A) and the air guard (B) and
then separate the condenser from the radiator.

|
11. |
Remove the radiator mounting bracket (A) and
then pull the radiator upper from vehicle.
Tightening
torque:
8.8 ~ 10.8 N.m (0.9 ~ 1.1 kgf.m, 6.5 ~
7.9 lb-ft)
|


|
12. |
Installation is in the reverse order of
removal. |
13. |
Fill the radiator with coolant and check for
leaks.
•
|
Bleed air from the cooling system.
|
-
|
Start engine and let it run until
it warms up. (Until the radiator fan operates 3 or 4
times.) |
-
|
Turn off engine and let it cool
down. Check the coolant level and add coolant if needed.
This will allow trapped air to be removed from the
cooling system. |
-
|
Put the radiator cap on tightly,
then run engine again and check for
leaks. | | |
Radiator Cap Testing
1. |
Remove the radiator cap, wet its seal with
engine coolant, then install it to pressure tester.

|
2. |
Apply a pressure of 93 ~ 123kPa (0.95 ~
1.25kgf/cm², 14 ~ 19psi). |
3. |
Check for a drop in pressure.
|
4. |
If the pressure drops, replace the cap.
|
Radiator Leakage Test
1. |
Wait until engine is cool, then carefully
remove the radiator cap and fill the radiator with engine coolant,
then install a pressure tester on it.

|
2. |
Apply a pressure of 93 ~ 123kPa (0.95 ~
1.25kgf/cm², 14 ~ 19psi). |
3. |
Inspect for engine coolant leaks and a drop in
pressure. |
4. |
If the pressure drops, check hoses, the
radiator and the water pump for leakage. If there is no leakage,
inspect the heater core, the cylinder block and the cylinder head.
|
5. |
Remove the tester and reinstall the radiator
cap.
Check for engine oil in coolant and/or
coolant in engine oil.
