Product Description ACDelco Gold (Professional) Air Conditioning Compressors are a high quality alternative to Original Equipment (OE) parts. These A/C Compressors pump refrigerant through the system and are a high quality replacement for many vehicles on the road today. The compressors are typically engine driven via the drive belt, and an A/C compressor clutch can be used to engage and disengage the compressors. Hybrid vehicles are typically equipped with an electric motor driven compressor. The compressors are lubricated by OEM specific 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. &#9888;<b> WARNING:</b> Cancer and Reproductive Harm - www.P65Warnings.ca.gov

Signs of Wear & Troubleshooting - Section 3 - Header To check your A/C system for leaks:
Signs of Wear & Troubleshooting - Section 3 - Bullet 1 Use 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.
Good Maintenance Practices - Section 3 - Bullet 1 Use the proper O-ring for the system
Good Maintenance Practices - Section 4 - Header When replacing your compressor, it is very important to use suction screens and inline filters on liquid lines.

Good Maintenance Practices - Section 3 - Header Your 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:
Signs of Wear & Troubleshooting - Section 2 - Header Your 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:
Good Maintenance Practices - Section 2 - Header Your 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.
Good Maintenance Practices - Section 1 - Header Your 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. If you notice any of the following conditions, have your vehicle checked right away:
