Hyundai 97139-3X000 Core & Seal Assembly-Evaporator

To remove the evaporator, first have the system discharged and recovered by a dealer service department or automotive air conditioning shop. Then, disconnect the negative battery cable. For 2006 and earlier models, ensure you have the activation code for the anti-theft radio before disconnecting the battery. From the engine compartment side of the firewall, disconnect the air conditioning lines from the evaporator inlet and outlet pipes, and cap the open fittings. Inside the vehicle, remove the dash and the glove box support bracket. Disconnect the thermostatic switch electrical connector, vacuum line from the door motor, and vacuum line between the door motor and the heater unit. Remove the upper and lower evaporator case mounting bolts, followed by the evaporator unit from the vehicle. Remove the sponge pad insulating the evaporator inlet and outlet pipes. Cut the foam lining the openings on both sides of the evaporator case and unclip the upper and lower evaporator cases. Detach the thermostatic switch and thermistor as a single assembly. Remove the evaporator unit from the lower case and the expansion valve assembly from the evaporator. For 2007 and later models, remove the heater core and the heater assembly lower case, then slide out the evaporator core. If the evaporator core needs cleaning, wash it with soapy water and a soft brush or blow it off with low-pressure compressed air. To install the evaporator, replace any O-rings with ones specific to the refrigerant type and lubricate them with refrigerant oil. Finally, have the system evacuated, recharged, and leak tested, and add the correct amount and type of refrigerant oil if a new evaporator was installed.
