  • 2025-11-26: Released new procedure.
Informational PurposesAn informational icon, calling your attention
Note
This is the preferable procedure to replace the supermanifold and compressor, using the Heat Pump HVAC Debris Flush Adapter 1838504-E0-B to flush all A/C lines and the HVAC assembly so that the HVAC assembly and the A/C lines can be reused. If only the Debris Flush Adapter 1838504-E0-A is available, use the procedure described in A/C Compressor, Supermanifold and A/C Lines (Remove & Replace). If neither of the flush adapters, are available, use the procedure described in A/C Compressor, Supermanifold and A/C Lines (Remove & Replace) and also replace the HVAC assembly.
