(Refer to Body - "Front
Bumper") |
8. |

(Refer to Body Electrical System - "Head
Lamp") |
9. |
Remove the upper mounting bracket
(A).
|
10. |

connector (A).
|
11. |

the A/C condenser (B) from radiator.
|
12. |
Disconnect the radiator assembly from
vehicle. |
13. |
Remove the cooling fan & reservior tank
(A) from the radiator (B).
|
14. |
Install in the reverse order of
removal. |
15. |

engine again and check for leaks. |
Radiator Cap Testing
1. |
Remove the radiator cap, wet its seal with
engine coolant, and then install it on a pressure
tester.
|
2. |
Apply a pressure of 93.16 ~ 122.58kpa (0.95 ~
1.25kg/cm², 13.51 ~ 17.78psi). |
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.
