Condenser HVAC: Service and Repair

Removal and Installation of Condenser

REMOVAL
1. Use a refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant.
2. Remove engine cover.
3. Remove air cleaner case, air hose and air duct.
4. Remove front grille.
5. Remove radiator fan shroud with cooling fan (VK45DE).




6. Remove mounting clips and bolts, and then remove bracket.
7. Remove radiator upper mount, move radiator and condenser to the engine side.




8. Remove mounting bolt from high-pressure flexible hose bracket.
9. Remove high-pressure pipe1 from vehicle clip.




10. Disconnect high-pressure flexible hose from condenser.
a. Set a disconnector (SST: 9253089912) on A/C piping.
b. Slide a disconnector backward until it clicks.
c. Slide A/C piping backward and disconnect it.

CAUTION: Cap or wrap the joint of condenser and high-pressure flexible hose with suitable material such as vinyl tape to avoid the entry of air.




11. Disconnect high-pressure pipe 1 from condenser.
a. Set a disconnector (SST: 9253089908) on A/C piping.
b. Slide a disconnector upward until it clicks.
c. Slide A/C piping upward and disconnect it.

CAUTION: Cap or wrap the joint of condenser and high-pressure pipe 1 with suitable material such as vinyl tape to avoid the entry of air.




12. Disconnect refrigerant pressure sensor connector.




13. Disconnect hood rock switch connector.
14. Remove radiator reservoir tank.




15. Remove mounting screws from condenser.




16. Pull condenser forward at an angle. Remove condenser from radiator.

CAUTION: Be careful not to damage the core surface of condenser and radiator.

INSTALLATION
Installation is basically the reverse order of removal.

CAUTION:
- Replace O-rings of high-pressure pipe 1 and high-pressure flexible hose with new ones, and then apply compressor oil to it when installing it.
- Female-side piping connection is thin and easy to deform. Slowly insert the male-side piping straight in axial direction.
- Insert piping securely until a click is heard.
- After piping connection is completed, pull male-side piping by hand to make sure that connection does not come loose.
- When recharging refrigerant, check for leaks.
