AC inline muffler

ginnmd on Tue February 05, 2008 10:42 PM User is offlineView users profile

I have a 1996 chev 5.7L pickup. The AC hoses have canisters in them. I think they are called inline mufflers. What exactly do they do, and are they necessary for proper function of the AC system. Thanks, I'm new to interesting forum.

Most likely they are mufflers which just deaden the compressor noise. Inline filters and/or mufflers are not "needed" for a system to operate correctly. But they are a nice addition to your system.

They are there because OEM has to use them to avoid those people who can hear the compressor run and consider it as compressor noise under warranty- and want a new compressor-- it helps deaden the resonance frequencies that can reduce the compressor warranty complaints for noise.......after the vehicle is out of warranty, the owner's attitude changes immensly- now they are happry the system cools- and of course that's the compressor running. Noise is only an issue if you're not paying for the replacement compressor....

-------------------------
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
