Product Details

The Four Seasons Accumulator 55606 is built for HVAC systems that use an accumulator on the suction side to manage refrigerant flow and moisture control. Its 3/4 in. inlet and outlet sizing, springlock end types, and steel construction support OE-style replacement on vehicles such as the 1991-1993 Ford Taurus, 1991-1993 Lincoln Continental, and 1991-1993 Mercury Sable. This part number 55606 is also listed for 1994 Lincoln Continental applications with R12 notes, making fitment verification important before ordering.

Four Seasons Accumulator products are positioned as direct-fit HVAC service parts, and this accumulator with hose assembly follows the original connection style used on the listed Ford, Lincoln, and Mercury models. If you are replacing a leaking suction line accumulator on a Taurus, Continental, or Sable, this assembly provides the correct springlock interface and switch-port configuration for the specified applications.

Common Problems This Part Can Address

• Refrigerant loss from a cracked or leaking accumulator assembly
• Damaged suction-side hose connections or springlock fittings
• Moisture contamination in the A/C system after accumulator failure
• Improper A/C operation caused by a worn switch-port housing
• Service issues on Ford Taurus, Lincoln Continental, or Mercury Sable R134a systems

Installation Notes and Tips

Verify refrigerant type, inlet and outlet style, and switch-port configuration before installation. This part uses male springlock inlet and female springlock outlet connections, so the existing line ends must match the OE layout. Confirm vehicle-specific notes for 1991-1994 Ford Taurus, Lincoln Continental, and Mercury Sable applications, especially where R12 or production-date notes are listed. Recover refrigerant properly and inspect related O-rings, seals, and mating lines before assembly.

Quality Assurance

Four Seasons 55606 meets or exceeds OEM requirements and is built as a replacement accumulator with hose assembly for the listed applications. The Four Seasons Accumulator line is used for OE-style HVAC service parts that follow original fitment and connection specifications.
