Can this type condenser be flushed?

Hi all.

I had read here that certain late model condensers weren't good candidates for flushing. I was wondering wether mine was in that category or if it could be sucessfully flushed. It's kind of a moot point as I replaced it anyway along with the compressor/clutch assembly and accumulator but I wouldn't mind keeping it as a spare if it in fact can be flushed. TIA...

That's a parallel flow unit, going to be very hard to flush. If your compressor went to pieces, scrap the condenser too. The nice thing about that one is it is solid aluminum so you can get a couple dollars for it as scrap metal.

If your vehicle suffered a complete compressor failure.....and if you are replacing this unit....may be interested in this unit......post contact info.....planning some serious testing of different flush procedures and need some canidates.

The replacement recommendation stems from the fact that these Parallel Flow Condensers (PFC) are difficult to clean. Without professional flushing equipment, the understanding of the internal flow paths, and the understanding of the failure and debris load; PFC's will not be successfully flushed with the common DIY tools such as the little 1 qt flush guns or aerosol products and therefore, IMHO, should be replaced.

Even with professional flushing equipment, in the cases of destructive compressor failure; it is common for many a shop to replace a PFC to eliminate any question or doubt about the condensers cleanliness or performance. As long as the components remain inexpensive and reasonably easy to change, this is just a safe, smart, and practical business practice. Some vehicles already have, and the OEM's tell us that this will become more common, a modular one piece cooling assembly (radiator, oil and or trans cooler, A/C condenser, and electronics cooling). Because of the expense of such a components replacement, this will make effective PFC flushing more in demand.

We have been supplied many complete systems from OEM's that have suffered catastrophic compressor failures, and we have successfully flushed the heat exchangers. Some of the condensers have had the inlet completely blocked (packed) with metal debris. So aginn, IMHO, it can be done.

We do advocate methods to test for cleanliness before reusing any heat exchanger, and do not claim that just using our equipment guarantees a clean component; for there are way too many variables to be evaluated and considered in each failure. Professional flushing equipment is no different a tool than a screwdriver; in competent hands it is amazing what can be done with such a tool, in the wrong hands you can hurt yourself or do more damage than good.

ICEMAN, let me know what we can share, supply, or help with in regards to your "serious testing".

As I stated in my initial post, this condenser has already been replaced. This site has helped me tremendously so the least I can do is say that if you want it, it's yours for the cost of shipping. I've still got the box that its ACDelco replacement came in. I see you're in West Palm Beach. I'm just up the road in Palm Beach Gardens. Heck, I'd be happy to drop it off if you'd like. Email me at [email protected] if you're interested...

No problem...send them right along....can not have any holes worn in them......which may be the case...since it is a known fact...that shoes are a 'option' for you....but....anyway if they are in good condition.....and since TurboTax has an 'appraisal' section for charity donations...send them....they will be put to a good cause...the lowering of my tax requirements.

LOL, shoes what the hell are shoes. Thought all us Arizona red necks just wear cowboy boots! You know how hard it was to find clipless cowboy boots for my MTB rides.
