🧊 Function & Technical Role
-
Purpose: The accumulator/receiver-drier removes moisture and debris from refrigerant before it circulates through the A/C system. It prevents internal corrosion and protects components like the compressor and expansion valve.
-
Accumulator vs. Drier:
-
Accumulator: Generally installed in or near the evaporator outlet on orifice tube systems.
-
Receiver-Drier: Located between condenser and expansion valve in TXV systems.
-
-
Design Features:
-
Integrated sight glass in older versions for refrigerant charge visibility.
-
Internal oil return ports may be included in OE-grade units.
-
Pressure/temperature cutoff switches may be ported externally depending on model.
-
🚘 Vehicle Applications
Most commonly found on:
-
GM Trucks and SUVs (late 1970s–mid 1990s) including:
-
Chevy C/K Series
-
Suburban, Blazer, and G-Series Vans
-
-
Jeep Wagoneer and Jeep SJ Models (1980s vintage systems)
-
Ford Light Trucks (select models using R12 systems)

🔧 Confirm system type (orifice tube vs TXV) and port layout before ordering — incorrect configuration can cause system blockage or compressor failure.
