Product Details

Four Seasons 33134 is an HVAC A/C accumulator used in the low-side refrigerant circuit to help manage moisture and liquid refrigerant before it reaches the compressor. The Four Seasons Accumulator line focuses on OE-style service replacement parts, and this unit follows the original connection style and dimensions needed for the listed Buick, Chevrolet, Oldsmobile, and Pontiac applications. If you are replacing a leaking or saturated accumulator on a 1994-1997 Buick Regal or a 1994-1997 Chevrolet Lumina, this part number provides the correct fitment profile for those vehicles.

This part cross-references Gates 21711 and UAC RD1711C for the same application.

What It Helps Fix

• Refrigerant leaks at the accumulator housing or fittings
• Moisture contamination in the A/C system
• Poor cooling caused by restricted or saturated accumulator performance
• Damaged O-ring sealing surfaces at the inlet or outlet connections
• Service replacement needs after compressor or system repair

Installation Notes

Verify the inlet and outlet connection style, thread size, and body dimensions before installation. Replace the O-rings with clean, correctly lubricated seals during service, and evacuate and recharge the system according to the vehicle manufacturer procedure. Mounting hardware is not included.

Quality Assurance

Four Seasons 33134 is manufactured as an OEM-level replacement and is listed as meeting or exceeding OEM requirements for the specified applications. The aluminum construction and OE-style fitment support consistent service results on compatible Buick, Chevrolet, Oldsmobile, and Pontiac models.
