Product Details

This A/C accumulator is used in the low-side refrigerant circuit to help manage moisture and debris in the system while supporting stable HVAC operation. It is a fitment-specific replacement for rear A/C applications on Chevrolet Tahoe, GMC Yukon, Cadillac Escalade, and Suburban models listed above.

Common Repair Uses

  • Replaces a leaking A/C accumulator on rear A/C systems
  • Addresses moisture contamination in the HVAC refrigerant circuit
  • Supports repair of weak or inconsistent cabin cooling
  • Helps correct accumulator-related refrigerant flow restrictions
  • Used during A/C service after component replacement or system opening

Installation Notes

Before installation, verify the vehicle uses rear A/C and confirm the part number against the original component. Replace any disturbed seals or O-rings as required by the service procedure, evacuate the system, and recharge with the specified refrigerant and oil type. Proper flushing and leak checking are recommended whenever the A/C system has been opened.
