How to Flush AC System

http://www.buyautoparts.com/ac-compressor/auto_ac_compressor.htm

When replacing an ac compressor you should always flush the entire ac system before installing the new compressor. Metal shavings or other debris from the defective compressor will contaminate the ac system. To flush the ac system shoot the flush fluid in one side of the compressor hose fittings. Using shop air, push the fluid through the entire system and out the other port.

This flush is performed before the removal of the old drier. The contamination will be flushed to the old drier and then removed with the old drier. A flush of the AC system can also be performed with the system apart flushing each piece one at a time. The system flush is extremely important and must be performed to remove all contamination from the system.

@jimrharper What's the best way to flush the Condenser and the evaporator?. I'm replacing the Compressor and the Accumulator. The orifice tube was blocked. Before I put the new parts on I want to flush the system. Do you suggest I evacuate the system and flush the parts separately? I'll wait for your replay

Hi, so i have this 93 cadillac 60 special and well the compressor don't not work properly. i bought the bypass pulley and tried to remove the ac compressor to install it but i am not so much of a mechanic, i just want to save some money. so i managed to get the 4 bolts one side but the compressor hose fittings are still tight down to the compressor and thats what i want to know. What would happen if i just unbolt the hose fittings? i have not drained anything yet. thanks.

And this is exactly how you should NOT flush a system. Doing it this way will fill the drier or accumulator with solvent and crud that will not come out.. In addition, if it's a CCOT system, it will plug the orifice tube screen, rendering your system dead.

Always disconnect all components. Flush the condenser, the evaporator, and hoses separately. Replace the drier/accumulator and install a liquid line filter, especially after a compressor failure.

@eisman07 ya and just replace the drier and expansion valve after you flush it out  plus be sure to get new o-ring seals

Okay, the flush solvent that I have said not to flush the expansion valve or drier, so wouldn't I need to disassemble the system and flush the components separately?
