    Note
    Carefully position the line so that oil does not drip out.
  10. Release the locking tab, and then disconnect the electrical connector from the high pressure temperature subcool sensor.
    Warning IconA warning icon, calling your attention to a possibly risky situation
    CAUTION
    DO NOT push down on the red locking tab. Pull the tab away from the connector until the connector is unlocked, and then continue pulling to release the connector.
  11. Use the P/T sensor socket to remove the high pressure temperature subcool sensor from the supermanifold.
    Warning IconA warning icon, calling your attention to a possibly risky situation
    CAUTION
    Use only hand tools to remove the PT sensor. Impact or power tools will break the threads.

    CAUTION
    Use only the P/T sensor socket to remove the sensor. Using other tools can damage the connector housing.
    Informational PurposesAn informational icon, calling your attention
    Note
    For Sensata sensors, use the 24mm thin wall P/T sensor socket (1600833-00-A). For Bridgeport sensors, use the 21mm P/T sensor socket (1565836-00-A).

  12. Record the part numbers and serial numbers of the old and new sensors in the repair order.

Install

  1. Lubricate the new high pressure temperature subcool sensor threads and O-ring with the appropriate A/C oil. See Fluids and Capacities for A/C oil specifications.
  2. Install and hand-tighten the high pressure temperature subcool sensor until the sensor O-ring just makes contact with the Supermanifold.
    Informational PurposesAn informational icon, calling your attention
    Note
    Use an inspection mirror to visualize this and subsequent steps.
  3. Manually back off and tighten the high pressure temperature subcool sensor in an incremental manner so that the sensor O-ring properly slides into the chamfer in the Supermanifold.
  4. If the high pressure temperature subcool sensor O-ring appears to pinch, or no longer slides into the chamfer, stop and reverse thread the sensor until the O-ring no longer appears to be pinched.
  5. Continue to back off and tighten the high pressure temperature subcool sensor until the O-ring slides completely into the chamfer and is no longer visible.
    Informational PurposesAn informational icon, calling your attention
    Note
    There should be no gap, and the sensor body should be bottomed out against the Supermanifold.
  6. Use the P/T sensor socket to tighten the high pressure temperature subcool sensor to the specified torque value.
