15.Condenser
A: REMOVAL
1) Using the refrigerant recovery system, dis-
charge refrigerant. Refrigerant Recovery Procedure.>
2) Disconnect the ground cable from battery.
3) Remove the bumper upper cover.
4) Disconnect the pressure hose and pipe from the
condenser.
5) Remove the 4 bolts, lift the condenser and pull
out from the space between the radiator and
bumper.
CAUTION:
•Be careful not to damage the condenser fins.
If a damaged fin is found, repair it using a thin
screwdriver.
•If the condenser is replaced, add an appropri-
ate amount of compressor oil to the compres-
sor. Compressor Oil.>
B: INSTALLATION
1) Install in the reverse order of removal.
CAUTION:
Replace the O-rings on hoses or pipes with new
parts, and then apply compressor oil.
2) Charge refrigerant. DURE, Refrigerant Charging Procedure.>
Tightening torque:
Refer to “COMPONENT” of “General Descrip-
tion”. UNIT, COMPONENT, General Description.>
ATOR FAN, COMPONENT, General Descrip-
tion.>
C: INSPECTION
1) Check to see that the condenser fins are not
clogged with debris or insects. Blow with com-
pressed air or flush fins with water as needed.
2) Inspect for oil leakage from the condenser. If a
failure is found, replace the condenser with a new
one.
