Detailed Description

The Four Seasons 33066 accumulator is used in the A/C system to manage refrigerant flow and help maintain proper system operation on vehicles with the correct factory air setup. Its steel housing, OE-style inlet and outlet design, and integrated service port support accurate replacement of the original accumulator on 1994 Ford Ranger and 1994 Mazda B-series trucks listed in the fitment data. This part cross-references UAC RD2152C for the same application.

With a 5/8 in. inlet, 5/8 in. outlet, and switch port diameter of 0.472 in. (12.000 mm), this unit is built around the specified connection points rather than a universal layout.
