See Figures 1, 2, 3 and 4
- Remove the evaporator assembly from under the dash panel. Follow all Air Conditioning precautions.
- Remove the electronic thermostat retaining clip, grommet and sensor from the assembly.
- Remove the clips and attaching screws.
- To remove the lower case, slit the case parting face with knife, since the lining is separated when removing the evaporator.
- Remove the cover and then remove the core.
- Tear off the insulation from around the expansion valve.
- Remove the expansion valve. Use a backup wrench to prevent the valve tubing from twisting.
- Install the evaporator core into the case, make certain insulation is in good condition and use new seals.
- Make certain to position the themosensor close to the center of the core.
- Coat all threads and O-rings with refrigerant oil. Add approximately 1.5 ounces of refrigerant oil if this is a new evaporator.
- Using a backup and flare nut wrench, install the expansion valve.
- Install the housing halves and retaining clips. Be careful not to damage the seals.
- Install the evaporator assembly.
- Connect the inlet and outlet pipe to the evaporator.
- Evacuate, leak test and charge the air conditioning system as outlined in General Information & Maintenance .
After you have made repairs you should take the vehicle to a licensed air conditioning technician to have the system tested for leaks then recharged. Newer air conditioning systems equipped with R134a refrigerant are NOT compatible with R-12 refrigerant.
