ACDelco 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. ⚠ WARNING: Cancer and Reproductive Harm - https://www.P65Warnings.ca.gov

Features and Benefits:

  • – Always lubricate O-rings with clean refrigerant oil
  • – Always replace sealing caps on service ports
  • – Inadequate cooling or heating temperatures when using the air conditioning or heating system
  • – Keep dirt and foreign material from all sealing surfaces
  • – Musty smell when the air conditioning or heating system is activated
  • – Recover refrigerant from the system when or if necessary
  • – The vehicle's temperature gauge indicates a 'red' condition
  • – Thoroughly clean all fittings and do not over torque beyond what is recommended
  • – Use the proper O-ring for the system
  • When 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.
  • 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:
  • 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.
  • 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:
