Installation Notes

Verify inlet and outlet fitting style before installation: 5/8 in. female springlock inlet and 5/8 in. male insert O-ring outlet. Confirm the vehicle does not require a service port or switch port on the accumulator, since this unit is listed without either feature. Replace sealing components as needed, evacuate and recharge the system according to factory service procedures, and inspect the surrounding lines for wear or corrosion before final assembly.

Quality Assurance

Four Seasons lists this accumulator as meeting or exceeding OEM requirements. The steel construction and direct-fit dimensions support consistent replacement service for the specified Volvo applications.
