Removal and installation of the evaporator K/V with expansion valve (Honda Accord 6)

Warning! The air conditioning system is under constant high pressure. Never disconnect refrigeration lines or remove any system components without first discharging the system. Discharging the air conditioning system must be done by an experienced technician in a car service workshop. Always wear safety glasses when disconnecting refrigeration lines!

When replacing air conditioning system components, a certain amount of replacement refrigeration oil will be required to fill the volume of the new unit. Use only oil suitable for use in R-134a systems (check the container label carefully).

Removal

1. Discharge the air conditioning system in a specialized workshop.

2. Disconnect the negative cable from the battery.

Warning! If the car stereo system is equipped with a security code, make sure you have the correct combination to activate the audio system before disconnecting the battery!

3. Remove the bolts and disconnect the two refrigeration lines from the evaporator.

4. Immediately plug open line ends and fittings to prevent dirt from entering the system.



5. Remove the passenger knee support, the metal bar underneath it and the storage box with its frame (see Chapter Body).

6. Disconnect the electrical wiring from the thermostat.



7. Release the fasteners securing the evaporator casing to the engine compartment bulkhead and instrument panel.

8. Disconnect the drain hose and remove the evaporator assembly from the vehicle.

9. Remove the temperature sensor from the evaporator.

10. Remove the air filters with trays (see Chapter Settings and ongoing maintenance), then unscrew the screws, separate the casing into two halves and release the evaporator from it. If necessary, remove the expansion valve.

Installation

1. Installation is carried out in the reverse order. Do not forget to replace the sealing rings of the nipple connections - before installation, lubricate the new rings with refrigeration oil R-134a. Tape the capillary tube of the expansion valve to the suction line and install the temperature-sensitive sensor in its regular place.



2. Charge the system and check it for leaks in a specialized workshop. When replacing the evaporator, add about 40 ml of refrigeration oil to the system.
