What exactly are you flushing because that condenser is a bypass type and cannot be flushed.

Aww, there is tubes, one with a muffler and another without. The evaporator. Yes, I have researched and found different sites that say you can flush condenser and some say you can't. I have come to conclusion just to replace it. Let me know if I missed something? I appreciate it. Thanks.
