Product Details

The Four Seasons Accumulator line focuses on replacement HVAC components that match original system architecture. This accumulator uses an aluminum tank-and-tube style construction with pad-mount fittings, a 13 mm switch port diameter, and a service port for system access. It is built for applications that require an accumulator rather than a receiver drier, and it cross-references Global Parts Distributors LLC 1411993 and UAC RD11224C for the same application. If you are servicing an A/C system on a Ford, Chevrolet, or GMC vehicle that uses this configuration, Four Seasons 34002 provides the correct style and connection layout for repair work.

Common Problems It Can Address

• Loss of A/C cooling performance after accumulator failure
• Moisture control issues in the refrigerant circuit
• Restricted refrigerant flow caused by a damaged internal desiccant assembly
• Leaking accumulator housing or fittings
• Service port or switch port replacement needs during HVAC repair

Installation Notes and Tips

Confirm pad-mount inlet and outlet dimensions before installation, and verify that the vehicle uses an accumulator-style HVAC layout. Replace the accumulator when the A/C system has been contaminated, opened to atmosphere, or repaired after a compressor failure. Always evacuate and recharge the system according to factory service procedures, and inspect seals, O-rings, and mating surfaces before assembly. For fitment verification, compare the original unit to Four Seasons 34002 and confirm the service port and switch port locations match the vehicle application.

Quality Assurance

Four Seasons states that this accumulator meets or exceeds OEM requirements, supporting a replacement standard aligned with original equipment specifications. The aluminum construction and OE-style fitment details help maintain proper HVAC system function when installed in the correct application.
