Good Maintenance Practices - Section 1 - Bullet 1Musty smell when the air conditioning or heating system is activated
Good Maintenance Practices - Section 3 - HeaderYour A/C system is a sealed system, which includes different components connected by hoses, tubes, or lines. To keep the system leak free, inlet and outlet fittings have O-rings or seal washers, and the lines have leak free fittings. To help prevent leaks in the A/C System, follow these guidelines when servicing connections:

Product DescriptionACDelco Gold (Professional) A/C Compressors are the high quality alternative to Original Equipment (OE) parts. The compressor is typically engine driven via the accessory belt, and a clutch on the compressor is used to engage and disengage the compressor. Hybrid vehicles are typically equipped with an electric motor driven compressor. The compressor draws in cool refrigerant gas from the evaporator and pumps it to a much higher pressure. The high pressure gas travels on to the condenser. The compressor is lubricated by refrigerant oil. ACDelco Gold (Professional) parts are manufactured to meet your expectations for fit, form, and function, making them a smart choice for General Motors vehicles, as well as most makes and models, including special applications. These high-quality parts are backed by General Motors. Some ACDelco Gold parts may have formerly appeared as ACDelco Professional. ⚠<b> WARNING:</b> Cancer and Reproductive Harm - www.P65Warnings.ca.gov

Signs Of Wear &#38; Troubleshooting - Section 2 - HeaderYour A/C system must be maintained with the correct level of refrigerant and appropriate pressure to work properly. An A/C system leak, which could result in incorrect fluid or pressure levels, could potentially harm or interfere with the performance of your A/C system. This would result in lack of or insufficient cooling performance. Common causes of A/C system leaks include:
Terminal TypeSpade
Mounting TypeCase Mount
Connector ShapeRectangle

Good Maintenance Practices - Section 4 - HeaderWhen replacing your compressor, it is very important to use suction screens and inline filters on liquid lines. These filters and screens will catch any debris in the system to avoid damage to the new compressor. ACDelco also recommends system flushing using native refrigerant before installing a new compressor.
Coil Clock Position12
Good Maintenance Practices - Section 2 - HeaderYour A/C system requires proper air flow to operate effectively. Poor air flow across the condenser will impact system performance and can increase refrigerant system pressure. Make sure air flow into your system is not obstructed by bugs, leaves, dirt, or other contaminates in between tune ups.
Signs Of Wear &#38; Troubleshooting - Section 1 - Bullet 1Lack of or insufficient cooling, excessive clicking sounds, unusual noises, or growling when using the A/C system could be a sign of a worn A/C compressor or components. This could be due to:

Signs Of Wear &#38; Troubleshooting - Section 3 - Bullet 1Use a leak detection dye, such as ACDelco Fluorescent Tracer Dye. Be sure to use the dye that is specified for use with your systems oil and refrigerant type.
Signs Of Wear &#38; Troubleshooting - Section 3 - Bullet 2Look for dirt or containment build up around hose or line connections. This could be a sign that oil, which would attract and hold contaminants, is leaking out of the connection.
Good Maintenance Practices - Section 1 - HeaderYour vehicle's air conditioning (A/C) system should be routinely checked by a professional technician. This should occur approximately every 12 months, though you should check your owner's manual for more specific recommendations. Any related maintenance should be handled only by professionals.
