Is this a leaking water pump

Been dealing with AC for quite some time. If the compressor fails in an R-134a system the condenser, a parallel flow type, had to be replaced. These are impossible to clean, same with the dryer, and the rest of the system has to be flushed out with approved flushing equipment.

A deep vacuum under 500 microns has to be drawn, and fresh PAG injected from a metal sealed can, it cannot be exposed to any moisture, it turns into paste if it does. Then the system properly charged to specifications.

If you dealer does not service your vehicle in this manner, you will have compressor failures again and again, and again.

I am gathering he is NOT servicing your vehicle in this manner. One way of cheating is to add a filter at the inlet of the compressor that doesn't really work either. with debris in the system from a failed compressor, that filter will plug up.

This was never a problem with R-12, tube and fin condensers were easy to clean, and the mineral oil used repelled moisture. Is a problem now, and has been since 1992. Now they are talking about getting rid of R-134a, claim it is not so environmentally after all, claim its causing global warming. Never proved R-12 was poking holes in the ozone layer, deep study shows R-12 is completely biodegradable. But we never will have an EPA that admits to making mistakes.
