Product Details

The accumulator is a key part of the air conditioning system, helping manage refrigerant flow and moisture control on the low-pressure side of the HVAC circuit. Four Seasons 83129 is built as a complete aluminum unit with a 3.500-inch body diameter and 8.000-inch body length, using 5/8-inch male springlock inlet and outlet fittings for the listed Ram truck applications. The Four Seasons Accumulator line focuses on replacement components for A/C service work, and this part number 83129 is also referenced in aftermarket interchange listings for the same application.

This part cross-references Carlson 7652 and Spectra Premium 0210024 for the same application. It is a direct-fit option for Dodge Ram 2500 and Dodge Ram 3500 owners replacing a worn or contaminated accumulator in the factory HVAC system.

Common Issues This Part Can Address

• Restricted refrigerant flow through a failing accumulator
• Moisture buildup in the A/C system
• Leak concerns at aging springlock connections
• Reduced cooling performance from a damaged accumulator housing
• Service issues during A/C system repair on Ram 2500 and Ram 3500 trucks

Installation Notes and Tips

Verify the vehicle uses the listed male springlock inlet and outlet configuration before installation. Inspect the mating seals, lines, and surrounding HVAC components during service, and confirm the service port location matches the original setup. Because mounting hardware is not included, reuse or source the correct hardware as needed for the vehicle.

For best results, evacuate and recharge the A/C system according to factory service procedures after replacement. Confirm fitment for 2007-2009 Dodge Ram 2500 and 2007-2009 Dodge Ram 3500 before ordering, especially when servicing a Four Seasons 83129 replacement on Ram 2500 or Ram 3500 HVAC systems.
