Proper flush

iceman2555 on Fri February 15, 2008 4:55 PM User is offlineView users profile

Here are some interesting photos of a failed compressor. This was one of several on the same vehicle.
I am seeing many more of these type failures...with compressors from various sources.
The system on this particular vehicle had a new compressor (from the GEN), new condenser, new manifold/hose assm, accumulator,orifice tube and was recharged with a quality recharge machine. On this trip several shops in the area that were having similar problem were visited and some vehicles were called back from evaluations.
I encounter a very strong chemical odor in each of the compressors that were evaluated. The flush chemical seems to be the common factor in all of these failures. Repairs were made on the same vehicles using a different flush and all new parts and the failures have not repeated themselves. The flush was supplied by a well know company...and no TRB..not that company.....it is a solvent based chemical. The company has recently stopped sales of this particular company. For those in the industry that do flush A/C system...do not simply take the word of a salesman....simply request an MSDS for the particular flush in question...check it out prior to using...some of this stuff is absolutely fatal to an A/C system.

The chemicals contained and the packaging sizes allow for some very aggressive and even regulated chemicals to be offered, as well as total junk. The instructions say pour in and blow out. This is junk marketing to the naive technician, and a recipe for disaster.

Unfortunately, with the technicians continued belief in this junk, and the fact that they do not make errors; it's time to just chime in with "flushing does not work" or "you cannot flush those". The fact is that flushing can be done very successfully, but it is never going to work when you combine inexperienced technicians with improper chemicals and ineffective methods.

The compressor pictures posted, clearly indicate that technicians are failing to address flushing basics:
With an adequate solvent volume; 1 qt. will never do it. (PHYSICS: volume, velocity, & agitation)
With a suitable chemical; not all that say they are, will be. (CHEMISTRY: know what you are using and why)
With methods to properly address solvent removal. (DILIGENCE: It must be all removed or it will dilute the oils)
With methods to test and confirm results. (One should never assume success)

What?

OK, we can take shortcuts; but we will not always be happy with the results.
