Condenser HVAC: Service and Repair

REMOVAL

WARNING: REFER TO THE APPLICABLE WARNINGS AND CAUTIONS FOR THIS SYSTEM BEFORE PERFORMING THE FOLLOWING OPERATION. FAILURE TO FOLLOW THE WARNINGS AND CAUTIONS COULD RESULT IN POSSIBLE PERSONAL INJURY OR DEATH.

NOTE: Before removing the A/C condenser, note the location of each of the radiator and condenser air seals. These air seals are used to direct air through the A/C condenser and radiator. The air seals must be reinstalled in their proper locations in order for the A/C and engine cooling systems to perform as designed.

1. Recover the refrigerant from the refrigerant system.
2. Remove the front fascia.

NOTE: It is not necessary to remove the quick-connect fittings from the transmission oil cooler tapping block when disconnecting the transmission oil cooler lines from the cooler.

1. Position the A/C condenser (combination cooler) into the engine compartment.
2. Carefully lower the A/C condenser straight down to engage the lower mounting brackets to the radiator.
3. Engage the upper A/C condenser mounting brackets to the radiator. Be sure that the upper retaining clips are fully engaged to the upper mounting brackets.
4. Remove the tape or plugs from the opened refrigerant line fittings and the condenser ports.
5. Connect the A/C discharge line and the A/C liquid line to the A/C condenser.
6. Connect the transmission oil cooler lines to the quick-connect fittings located on the transmission cooler tapping block. Be sure that the quick-connect fittings are fully engaged to the lines.
