Typical clutchless A/C compressor shown in illustrations. 6SEU16 A/C compressor similar.
- Disconnect and isolate the negative battery cable.
- Recover the refrigerant from the refrigerant system.
- Raise and support the vehicle.
- Remove the splash shield from the right side frame rail.
- Remove the accessory drive belt.
Disconnect the engine wire harness (1) from the compressor control valve (2).
- Remove the nuts (4) that secure the A/C discharge line (5) and the A/C suction line (6) to the A/C compressor (3).
- Disconnect the A/C discharge and suction lines from the A/C compressor and remove and discard the O-ring seals and gaskets.
Support the A/C compressor (1) and remove the three bolts (2) that secure the compressor to the engine and remove the compressor.
- Install plugs in, or tape over the opened refrigerant line fittings and compressor ports.
If the A/C compressor is being replaced, be certain to adjust the refrigerant system oil level. Failure to properly adjust the refrigerant oil level will prevent the A/C system from operating as designed and can cause serious A/C compressor damage.
The A/C accumulator and the A/C liquid line must be replaced if an internal failure of the A/C compressor has occurred. Failure to replace the A/C accumulator and the A/C liquid line can cause serious damage to the replacement A/C compressor.
When replacing multiple A/C system components, see the Refrigerant Oil Capacities chart to determine how much oil should be removed from the new A/C compressor.
Replacement of the refrigerant line O-ring seals and gaskets is required anytime a refrigerant line is disconnected. Failure to replace the rubber O-ring seals and metal gaskets could result in a refrigerant system leak.
