VISTEON A/C COMPRESSOR





1. Position the A/C clutch field coil (1) squarely onto the front of the A/C compressor (2).

CAUTION: Position the A/C clutch field coil so that the coil positioning tabs and the wire harness lead are oriented in the correct direction. Failure to correctly position the field coil on the A/C compressor will result in field coil damage.

2. Align the field coil positioning tabs to the recessed area at the front of the A/C compressor and install the clutch field coil onto the compressor using a two jaw puller (3), compressor field coil installer (Special Tool 9352 in Kit 9349) (4) and the compressor field coil installer spacer (Special Tool 9353 in Kit 9349) (5).




3. Position the clutch field coil wire lead and bracket (2) to the A/C compressor (3) and install the screw (1) that secures the bracket to the compressor. Tighten the screw to 4 Nm (35 in. lbs.).




4. Align the pulley and bearing assembly (1) squarely onto the front of the A/C compressor (2).

NOTE: A distinct change of sound during the clutch pulley tapping process indicates that the pulley and bearing assembly has bottomed out against the compressor housing.

5. Using clutch pulley installer (Special Tool 9355 in Kit 9349) (3) and a hammer (4), install the pulley and bearing assembly onto the front of the A/C compressor. Tap the installer with a hammer until the pulley and bearing assembly has bottomed against the compressor housing.




CAUTION: If the snap ring is not fully seated in the groove it will vibrate out, resulting in clutch failure and severe damage to the A/C compressor.

NOTE: Install the snap ring with the beveled side of the snap ring facing outward.

6. Using snap ring pliers (Special Tool 9764 or equivalent) (1), install the snap ring (2) that secures the pulley and bearing assembly (3) to the front of the A/C compressor (4). Make sure the snap ring is properly seated in the groove.




7. Verify that there is adequate clearance for the clutch field coil wire lead (1) between the housing of the A/C compressor (2) and the pulley and bearing assembly (3).

NOTE: When installing an original or a new clutch assembly, try the original shims first. When installing a clutch onto a compressor that previously did not have a clutch, use the 1.0, 0.50 and 0.13 millimeter (0.040, 0.020 and 0.005 inch) shims from the clutch hardware package which is provided with the new clutch.

8. Install the clutch shims onto the compressor shaft.
9. Using a strap wrench (4), install the bolt (5) that secures the clutch plate (6) to the A/C compressor. Hold the clutch plate stationary with the strap wrench and tighten the bolt to 15 Nm (133 in. lbs.).




10. Using 90° wire gauges (1), check the air gap between the clutch plate (2) and the pulley and bearing assembly (3). If the air gap is not between 0.35 to 0.65 millimeter (0.014 to 0.025 inch), add or subtract shims as required.
11. Position the A/C compressor onto the mounting bracket.
12. Install the bolts that secure the A/C compressor to the mounting bracket A/C Compressor - Installation.
13. Connect the engine wire harness to the compressor clutch field coil connector.
14. Install the accessory drive belt Accessory Drive Belt - Installation.
15. Reconnect the negative battery cable.
16. Perform the Clutch Break-in Procedure A/C Clutch Break-In.
