Remove and Replace Components/Sub-Assemblies - Exception to SI for Assembly Plant

HVAC Module Components - Exceptions for Part R&R

  1. Evaporator Core is replaced in the SI documentation. However, for assembly plant repair, the entire module with the evaporator core should be replaced as a unit. Install new seal washers on the evaporator.
  2. Heater Core is generally replaced as a separate unit. Unless SI details how to remove the heater core w/o disassembly of the HVAC module, the entire module is required to be replaced.
  3. Broken/Cracked HVAC Module Case - these defects are not to be repaired per SI directions. The plastic assembly or module requires replacement

Condensors - Exceptions for Part R&R

  1. Condensers are serviced in SI documentation as individual units. However, majority of units employed arrive as CRA's (Condenser Radiator Assembly) If the condenser or radiator require replacement, the replacement should be a replacement CRA.
  2. RD desiccant bag replacement. Internal desiccant bag replacement although authorized in SI, is not to be done at assembly plant. If material contamination - from failed compressor or desiccant bag is noted, entire assembly to be replaced and not flushed.

A/C Hoses/Lines- Exceptions for Part R&R

  1. Line Splice - line rub through or damage are to be replaced with new assemblies and not line spliced.
  2. In-Line filters - Assembly plant is not authorized to employ install these filters
  3. Compressor Suction line screens - Assembly plant is not authorized to install suction screens or screen blocks unless specifically authorized by platform engineering.

Control Heads and Sensors - Exceptions for Part R&R

  1. Replace and reprogram control head.
