| 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.
