11. Remove the refrigerant pressure sensor for installation on new radiator, condenser and liquid tank assem-

bly. Refer to 

HA-38, "Removal and Installation for Refrigerant Pressure Sensor"

.

12. Remove both radiator, condenser and liquid tank assembly clips.
13. Remove radiator, condenser and liquid tank assembly.

CAUTION:

• Do not damage or scratch the radiator, condenser and liquid tank assembly and sub radiator core

when removing.

• When removing refrigerant components from a vehicle, immediately cap (seal) the component to

minimize the entry of moisture from the atmosphere.

• When installing refrigerant components to vehicle, never remove the caps (unseal) until just before

connecting the components. Connect all refrigerant loop components as quickly as possible to min-

imize the entry of moisture into system

INSTALLATION

Installation is in the reverse order of removal.

INSPECTION

Radiator, Condenser and Liquid Tank Assembly

1. Check radiator, condenser and liquid tank assembly for mud or clogging. If necessary, clean radiator, con-

denser and liquid tank assembly as follows:

• Be careful not to bend or damage the radiator, condenser and liquid tank assembly fins.

• When radiator, condenser and liquid tank assembly is cleaned without removal, remove all surrounding

parts such as radiator fan assembly and horns. Then tape the harness and electrical connectors to pre-

vent water from entering.

a. Apply water by hose to the back side of the radiator, condenser and liquid tank assembly core, point the

hose vertically downward.

b. Apply water again to all radiator, condenser and liquid tank assembly core surfaces once per minute.
c. Stop washing when no more dirt flows off the radiator, condenser and liquid tank assembly.
d. Blow air into the back side of radiator, condenser and liquid tank assembly core, point the air hose verti-

cally downward.
• Use compressed air lower than 490 kPa (5 kg/cm

2

, 71 psi) and keep distance more than 30 cm (11.8 in). 

e.  Blow air again into all the radiator, condenser and liquid tank assembly core surfaces once per minute

until no water sprays out.
