RESTRICTED DISCHARGE LINE - 4 Seasons

348. TECH TIPS. Tech Tip RESTRICTED . DISCHARGE line . Excessive high side pressure can force a compressor to make noise, even when the gauge readings don't show a pressure problem. A common condition, often overlooked, is a RESTRICTED DISCHARGE line . The DISCHARGE line , which connects the compressor outlet to the condenser inlet, can easily become RESTRICTED . While simple designs have just two ends on a section of barrier hose, many lines contain a muffler and/or filter. The muffler, which smoothes out compressor DISCHARGE pulses, may house baffles or filter screens or may be just an empty can. However, after a compressor failure, mufflers can trap debris.

1 348. TECH TIPS. Tech Tip RESTRICTED . DISCHARGE line . Excessive high side pressure can force a compressor to make noise, even when the gauge readings don't show a pressure problem. A common condition, often overlooked, is a RESTRICTED DISCHARGE line . The DISCHARGE line , which connects the compressor outlet to the condenser inlet, can easily become RESTRICTED . While simple designs have just two ends on a section of barrier hose, many lines contain a muffler and/or filter. The muffler, which smoothes out compressor DISCHARGE pulses, may house baffles or filter screens or may be just an empty can. However, after a compressor failure, mufflers can trap debris.

2 Also, a DISCHARGE line without a muffler can become RESTRICTED . The barrier hose may collapse internally, restricting flow. As the refrigerant leaves the compressor, it is a high pressure, high temperature vapor. The DISCHARGE line should have no effect on the refrigerant; pressure and temperature should remain constant. Any loss of heat can indicate the DISCHARGE line is RESTRICTED . To test for a restriction, use a digital pyrometer to check the temperature at both ends of the line . A temperature drop of 5 . F or more indicates the line is RESTRICTED and must be replaced. Paper Filter GM has recently added an in- line filter (pictured above) to the DISCHARGE hose on many vehicles.

3 The filtering material is a paper product, which looks very similar to the in- line fuel filter used on many GM carburetors. However, this filter is not serviceable. 2016 Copyright, All rights Reserv
