FORWARD FLUSH
Forward flushing (the same flow as normal system operation) is recommended for contaminated refrigerant or RAG oil.
IMPORTANT: Install a new filter inside the J 45268-1 for every flush. Service the filter with GM P/N 5651802 (in Canada, use P/N 729832). Remove and discard the check valve filter from the filter.
IMPORTANT: Always close the valve on the J 43600 ACR 2000 external refrigerant tank before starting the flush process.
To perform the forward flush, follow these steps:
1. Connect the flush filter adapter J 45268-1 to the suction port of the A/C compressor hose assembly flush adapter.
2. Connect the blue hose from the J 43600 ACR 2000 to the J 45268-1 flush filter adapter.
3. Connect the red hose from the J 43600 ACR 2000 to the discharge port of the A/C compressor hose assembly flush adapter.
4. Follow the instructions supplied with the J 43600 ACR 2000 and flush the A/C system.
