Detailed Description

Four Seasons 33103 is an A/C accumulator designed for the Buick Regal HVAC system in 1994 and 1995. The aluminum body measures 3.500 inches in diameter and 9.000 inches in length, with a 12.000 mm switch port diameter and O-ring sealing at both inlet and outlet connections. This part number 33103 is built as a complete unit for direct replacement in the specified accumulator location.

The Four Seasons Accumulator product line focuses on replacement HVAC components that match OE-style fitment and connection details. For this application, the accumulator uses green O-rings and the listed inlet and outlet thread sizes to support proper sealing in the A/C circuit. This part cross-references Gates 21622 for the same application.

What It Helps Address

• Loss of refrigerant storage in the A/C system
• Moisture management issues in the HVAC circuit
• Improper suction-side refrigerant flow control
• Leaking accumulator seals at O-ring connections
• Service replacement for a worn Buick Regal accumulator

Installation Notes and Tips

Verify the inlet and outlet thread sizes, fitting style, and switch port configuration before installation. Replace the accumulator when opening the A/C system for major service, and evacuate and recharge the system according to factory procedures after installation. Confirm the vehicle is a 1994-1995 Buick Regal with the accumulator-style HVAC layout shown in the fitment data.

Quality Assurance

This Four Seasons accumulator meets or exceeds OEM requirements for the listed application. Use it as a direct replacement for the specified Buick Regal fitment when the original part number and connection details match.
