A/C Compressor and Clutch Assembly: Notes

WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Internal A/C compressor components are not serviced separately. The A/C compressor is serviced only as an assembly. The clutch disc and hub, A/C compressor pulley and bearing and clutch field coil are serviceable.

The A/C compressor uses the following:

A non-serviceable shaft seal.
A pressure relief valve installed in the rear of the compressor to protect the refrigerant system against excessively high refrigerant pressures.
PAG oil or equivalent. This oil contains special additives required for the A/C compressor.
- PAG oil may have some slightly dark-colored streaks while maintaining normal oil viscosity. This is normal for this A/C compressor because of break-in wear that can discolor the oil.

Use standard oil matching procedures when installing new compressors. Refer to CLIMATE CONTROL SYSTEM - GENERAL INFORMATION & DIAGNOSTICS .
