Air Conditioning Compressor Replacement (5.7 L)
Removal Procedure
Important: Compressor related noise is generally air conditioning (A/C) system related and not always the compressor itself.
1.  Recover the refrigerant. 2.  Raise and suitably support the vehicle. 3.  Remove the serpentine drive belt. 4.  Remove the air conditioning (A/C) compressor and condenser hose bolt. 5.  Discard the O-ring.
6.  Remove the transmission oil cooler pipes from the engine bracket, if necessary.
7.  Disconnect the electrical connector from the A/C compressor.
8.  Remove the A/C compressor bolts. 9.  Remove the A/C compressor.
Installation Procedure
1.  If a NEW A/C compressor is being installed, add 60 ml (2 oz) of PAG oil to the compressor. (this compressor comes with a full charge of oil) 2.  If reinstalling the old A/C compressor perform the following:     2.1.  Drain, measure and record the amount of PAG oil in the A/C compressor.
    2.2.  If the measured amount of PAG oil drained is less than or equal to 60 ml (2 oz), add 60 ml (2 oz) of new, clean PAG oil to the A/C compressor.
    2.3.  If the measured amount of PAG oil drained is greater than 60 ml (2 oz), add the same amount of new, clean PAG oil to the A/C compressor.
    2.4.  Install the compressor crankcase oil drain bolt (1) to the replacement compressor.
    Tighten     Tighten the compressor crankcase oil drain bolt (1) to 20 N·m (15 lb ft).
3.  Install the A/C compressor. 4.  Install the A/C compressor bolts.     Tighten     Tighten the A/C compressor bolts to 50 N·m (37 lb ft).
5.  Connect the electrical connector to the A/C compressor.
6.  Install the transmission oil cooler pipes to the engine bracket, if removed.
7.  Install a new O-ring.
  Lightly coat the O-ring with a mineral base 525 viscosity refrigerant oil.
8.  Install the A/C compressor and condenser hose bolt.     Tighten     Tighten the A/C compressor and condenser hose bolt to 33 N·m (24 lb ft).
9.  Install the serpentine drive belt. 10.  Lower the vehicle. 11.  Recharge the A/C system. 12.  Perform a leak test on the A/C system.
The V7 is a 7 cylinder variable displacement AC Compressor.
General Motors V5 and V7 compressors have a refrigerant control valve.  A control valve measures refrigerant and adjusts the angle of the swash plate, to which the pistons are connected, and controls the stroke of the pistons.  If high pressure is measured, the control valve adjusts to shorten the stroke of the pistons, so less pressure is produced.  If, upon installation of a new compressor, there seems to be no ‘pumping’ from the compressor, it may be necessary to remove the control valve and blow off excess oil.  The control valve may be sensing no pressure and presuming the system is empty of refrigerant.
The Accumulator or Filter Drier should always be replaced when the Air Conditioning System is opened.  (see why)  The Orifice Tube, if equipped, should always be replaced and the Expansion Valve, if equipped, should at least be inspected for proper operation if not replaced.  (see why)
