Condenser HVAC: Service and Repair
REPLACEMENTCONDENSER
1. Recover the refrigerant with a recovery/ recycling/ charging station.
2. Disconnect the negative (-) battery terminal.
3. Remove the air duct (A) after loosening 3 fasteners.
4. Remove the radiator bracket (B) after loosening the bolts.
5. Remove the 2 nuts, then disconnect the discharge line and condenser line from the condenser. Plug or cap the lines immediately after disconnecting them to avoid moisture and dust contamination.
6. Remove the bolts, then remove the condenser (A) by lifting it up. Be careful not to damage the radiator and condenser fins when removing the condenser.
7. Install in the reverse order of removal, and note these items:
- If you're installing a new condenser, add refrigerant oil.
- Replace the O-rings with new ones at each fitting, and apply a thin coat of refrigerant oil before installing them. Be sure to use the right O-rings for R-134a to avoid leakage.
- Be careful not to damage the radiator and condenser fins when installing the condenser.
- Be sure to install the lower mount cushions of condenser securely into the holes.
- Charge the system, and test its performance. (Refer to HA-10)
DESICCANT
1. Remove the condenser, and then remove the bottom cap (B) from the receiver/drier tank (A).
TORQUE: 20-25N.m (2.0-2.5kgfm, 14.5-18.2 lb.ft)
WARNING: Use of impact wrench may cause cracking on the receiver/drier tank connecting pipe to the condenser.
2. Remove the desiccant (A) from the receiver/drier tank using a long nose plier.
3. Check for crumbled desiccant and clogged bottom cap filter.
4. Apply air conditioning compressor oil along the O-rings and threads of the new bottom cap.
5. Insert the new desiccant into the receiver drier tank. The desiccant must be sealed in vacuum before it is exposed to air for use.
6. Install the new bottom cap to the receiver drier tank.
NOTE:
- Always replace the desiccant and bottom cap at the same time.
- Replace the O-rings with new ones at each fitting, and apply a thin coat of refrigerant oil before installing them. Be sure to use the right O-rings for R-134a to avoid leakage.
- Be careful not to damage the radiator and condenser fins when installing the condenser:
- Be sure to install the lower mount cushions of condenser securely into the holes.
- Charge the system, and test its performance.(Refer to HA-10)
