Condenser HVAC: Service and Repair

CONDENSER CORE







Removal and Installation

NOTE:
- The condenser core is a combination cooler with the bottom rows being used as an oil to air transmission cooler. If a new A/C condenser is being installed to correct a suspected refrigerant leak due to fluorescent dye being found on the condenser, it should be verified that the dye is not a result of a transmission fluid leak.
- Installation of a new suction accumulator is not required when repairing the air conditioning system, except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator.
