Product Details

Four Seasons 83000 is an A/C accumulator for vehicles using a 3.500-inch diameter, 8.000-inch long aluminum housing with M27x2.000 inlet and outlet thread sizes. The accumulator is part of the Four Seasons Accumulator product line and is built as an OE replacement for HVAC systems that require dual O-ring connections and a complete-unit configuration. This part cross-references Monroe Shocks & Struts (e.g., 172918) for the same application.

What It Helps Address

• Loss of A/C system moisture control after accumulator failure
• Restricted refrigerant flow caused by a worn internal desiccant assembly
• Leaks at aging O-ring sealing surfaces
• Poor cooling performance from a damaged accumulator housing
• HVAC service issues on Chevrolet Cavalier and Pontiac Sunfire models

Installation Notes

Verify the vehicle uses a dual O-ring accumulator with no service port and no switch port before installation. Confirm inlet and outlet thread sizes, body dimensions, and mounting location against the original unit on the vehicle. Replace sealing O-rings during service and evacuate and recharge the A/C system according to factory procedures after installation.

Quality Assurance

Four Seasons lists this accumulator as meeting or exceeding OEM requirements and as an OE replacement part. It is engineered for direct-fit service on the specified Chevrolet Cavalier and Pontiac Sunfire applications.
