How to remove the A/C Accumulator on Chevrolet Express?

To remove the accumulator in a refrigeration system, start by discharging and recovering the refrigerant. Then, remove the coolant reservoir and battery. Disconnect the refrigerant inlet and outlet lines, making sure to cap or plug them immediately to prevent dirt or moisture from entering. Disconnect the electrical connector from the pressure cycling switch. Loosen the mounting bolt(s) on the bracket and remove the accumulator. If replacing with a new one, add one ounce of fresh refrigerant oil. For installation, reverse the removal steps and use new O-rings coated with clean refrigerant oil when installing the refrigerant lines. Finally, have the system evacuated, recharged, and leak tested.

Chevrolet Express A/C Accumulator

The Chevrolet Express A/C Accumulator protects the air conditioning system in the van by removing moisture and debris before the refrigerant reaches the compressor. Sitting on the low-pressure line right after the evaporator, the A/C Accumulator contains a desiccant bag that soaks up water and traps grit, preventing the compressor from rusting or scoring from the inside and maintaining cabin cooling. When the refrigerant vapor enters, the cylinder slows down the flow and separates the remaining liquid droplets, after which it sends the clean, dry gas further and stores excess oil for later circulation. Over the years, Chevrolet stuck to this style of cylinder. However, some other systems in the lineup had a receiver drier on the high-pressure side, but the main goal remained the same; only the placement and pressure conditions differed. The receiver drier works between the condenser and expansion valve while the A/C Accumulator always works between the evaporator and compressor on low pressure. Over time, the A/C Accumulator can also become saturated and lose efficiency. Because flushing is no way of getting out saturated desiccant or embedded debris, replacing the A/C Accumulator whenever the system is opened or after contamination is vital to reliable Express cooling and long compressor life, making the humble part one of the most cost-effective shields in any Express climate control arsenal for every Chevrolet driver.

Each OEM Chevrolet Express A/C Accumulator we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
