Radiator Repair Procedures

Removal and Installation

1. 1
   Disconnect the negative (-) battery cable from the battery.
2. 2
   Loosen the drain plug and drain the engine coolant. (Refer to Cooling System - "Coolant")
3. 3
   Remove the cooling fan. (Refer to Cooling System - "Cooling Fan")
4. 4
   Disconnect the upper radiator hose (A) and lower hose (B).

   

   

   When installing the radiator hoses, install them as shown in the illustrations.

   

5. 5
   Remove the radiator upper mounting bracket.

   

6. 6
   Remove the mounting bolts (A) between the radiator assembly and the A/C condenser, then remove the radiator (A) from the vehicle.

   Tightening Torque: 4.9 ~ 7.8 N·m

   

7. 7
   To install, reverse the removal procedure. Fill the radiator with coolant and check for leaks.

Inspection

1. 1
   Remove the radiator cap, apply engine coolant to the seal, then install the pressure tester on it.

   

2. 2
   Apply a pressure of 93.16 – 122.58 kPa (0.95 – 1.25 kgf/cm², 13.51 – 17.78 psi).
3. 3
   Check the pressure for any change.
4. 4
   If the pressure drops, replace the radiator cap.
5. 5
   Wait until the engine has cooled, then carefully remove the radiator cap and fill the radiator with engine coolant, then install the pressure tester.

   

6. 6
   Connect the tester to the radiator and apply a pressure of 93.16 – 122.58 kPa (0.95 – 1.25 kgf/cm², 13.51 – 17.78 psi).
7. 7
   Check for engine coolant leaks and pressure drop.
8. 8
   Remove the tester and install the radiator cap.

   Check whether engine oil is mixed with the coolant.
