REMOVAL & INSTALLATION
See Figures 1 and 2
In certain areas it may be illegal to service air conditioning components unless you are certified, consult with your local authorities.
- Recover the refrigerant from the system. Please refer to Routine Maintenance .
- Disconnect the negative battery cable.
- Remove the cooling unit.
- Separate the upper and lower halves of the cooling unit case. It is usually retained by screws and clips.
- Remove the expansion valve from the evaporator, if necessary. Refer to the appropriate procedure later in this section.
- Inspect the evaporator fins for blockage.
- Connect the expansion valve to the evaporator.
- Install the upper and lower case of the cooling unit.
- Install the cooling unit in the car.
- If the evaporator is being replaced, add 1.4-1.7 fl. oz. (40-50 cc) of refrigerant oil to the system. On 1984-1986 sedans and all wagons, use Densoil 6, Suniso 5GS or equivalent. On 1987-1993 sedans, use Densoil 7 or equivalent. On 1994 models, use ND-Oil 9, made expressly for use with R134a. Do not use R-12 refrigerant, oil or components on R134a systems and vice versa. Expensive system damage will result, as they are not compatible.
- Evacuate, charge and leak test the air conditioning system.
