With the design of the condenser, you will never flush the debris out.
Something else to keep in mind about flushing is that it follows the path of least resistance. In a serpentine-style condenser, there is only one path the refrigerant can follow so the flushing chemical will follow the same path from the entrance to the exit. In a parallel flow condenser, the flush may not flow through all the tubes if some are partially or completely blocked. Attempting to flush a dirty parallel flow condenser, is probably a waste of time.
These
compressors are very hard to find NEW. Just don't want you to have any
complications with it. PLEASE replace the receiver/drier and have your
old condenser and evaporator flushed very thoroughly if you can not replace them.
Let me know if you need a new condenser or evaporator as I will be happy to post another auction for you.
