REMOVAL & INSTALLATION
See Figures 1, 2 and 3
On models equipped with a Supplemental Restraint System (SRS) or "air bag,'' work must NOT be started until at least 90 seconds have passed from the time that both the ignition switch is turned to the LOCK position and the negative cable is disconnected from the battery.
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 engine under cover, if applicable.
- Unplug the electrical connections from the compressor.
- Label and disconnect the hoses from the compressor. Cap the openings immediately to keep moisture and dirt out of the system.
- Loosen and remove the compressor drive belt.
- Remove the compressor mounting bolts, then the compressor.
- If the compressor is to be replaced, drain the compressor oil into a measuring cup. Record the amount drained, then pour this amount of new oil into the new compressor. 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.
- Install the compressor with the mounting bolts. Torque to 18 ft. lbs. (25 Nm).
- Install the drive belt.
- Connect the hoses to the compressor. On 1984-1986 sedans and all wagons, torque the discharge line to 16 ft. lbs. (22 Nm) and the suction line to 24 ft. lbs. (32 Nm). On 1987-1993 sedans, torque the suction and discharge lines to 18 ft. lbs. (25 Nm). On 1994 models, torque the suction and discharge lines to 8 ft. lbs. (10 Nm). Always use new O-rings, if applicable.
- Engage the compressor electrical connections.
- Install the engine under cover, then connect the negative battery cable.
- Evacuate, charge and leak test the system.
