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 assembly, air hose and air duct.
4. Remove engine under cover, using power tools.
5. Drain engine coolant.
6. Remove radiator fan shroud with cooling fan after (VK45DE).




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




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




11. Disconnect high-pressure flexible hose from condenser.
a. Set a disconnector (92530-89912) 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 the pipe with suitable material such as vinyl tape to avoid the entry of air.




12. Disconnect high-pressure pipe 1 from condenser.
a. Set a disconnector (92530-89908) 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 the pipe with suitable material such as vinyl tape to avoid the entry of air.




13. Disconnect refrigerant pressure sensor connector.




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




16. Remove mounting screws from condenser.




17. 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 for A/C piping with new ones, and then apply compressor oil to it when installing it.
- Connection point for female-side piping is thin. So, when inserting male-side piping, take care not to deform female-side piping. Slowly insert in axial direction.
- Insert one-touch joint connection point securely until it clicks.
- After piping has been connected, pull male-side piping by hand to make sure piping does not come off.
- When recharging refrigerant, check for leaks.
