  Q: How to Maintain a Visteon A/C Compressor Clutch on Jeep Liberty?

  A:

  Before you do anything else, disconnect and separate the negative Battery Cable. Start by eliminating the accessory Drive Belt and after that disconnect the engine wire harness from the clutch field coil connector. Slide the A/C Compressor off its mount by turning the bolts and carefully remove the item with support. Lift up the compressor before removing the bolt holding the clutch plate to its shaft with the wrench; this bolt might be removed by hand or with an 8 x 1.25 mm bolt. All clutch plate shims must be removed from the hub or compressor shaft. After taking off the clutch plate and shim(s), use A/C Snap Ring Pliers 9764 to remove the snap ring that holds the pulley and bearing assembly to the front of the A/C compressor. Both the pulley and bearing assembly can be disassembled manually or using a two jaw puller. To end, take out the screw securing the clutch field coil wire lead bracket to the A/C compressor and then use the appropriate tool along with a two jaw puller to remove the clutch field coil from the front of the A/C compressor.

  Q: How to Remove and Replace the A/C Compressor Clutch on Jeep Liberty?

  A:

  Begin by placing the clutch field coil directly in front of the compressor, ensuring that the positioning tabs and wire harness are correctly directed, to keep them from being damaged. Place the field coil tabs into the holes at the front of the compressor and hold the clutch field coil in place with a two jaw puller and compressor field coil installer spacer. Place the clutch field coil wire lead and bracket over the A/C Compressor and use a screw to secure it, tightened to 4 Nm (35 in. lbs.). Check that the pulley and bearing are in place at the beginning of the compressor, because you'll hear a difference in sound as you inspect them. Attach the clutch pulley installer (Special Tool 9355 from Kit 9349) and use a hammer to put the pulley and bearing assembly into the clutch until it presses against the housing. Make sure the snap ring is seated to stop the clutch from failing. Snap ring goes into place using snap ring pliers (Special Tool 9764 or an equivalent) for security of the pulley and bearing assembly on the compressor. Make sure the clutch field coil wire lead from compressor housing is far enough from the bearing assembly and pulley assembly. If you are installing a new clutch assembly and the compressor didn't have one before, first put in the 1.0, 0.50 and 0.13 millimeter shims from the clutch hardware. Put the clutch shims on the compressor shaft and, with the plate stationary and the bolt fastened to 15 Nm (133 in. lbs.), secure the bolt holding the clutch plate with a strap wrench. Set the gap between the clutch plate and the entire pulley/bearings assembly by using 90° wire gauges and adjusting shims to end up with a 0.35 to 0.65 mm space. A/C compressor, secure it into place on the mounting bracket and secure it with bolts. Plug the wire harness cable from the engine into the compressor clutch field coil, slide the accessory belt back on and reattach the negative Battery Cable. Finally, complete the necessary procedure to break in the clutch.
