Detailed Description

The Four Seasons 33099 accumulator is used in the air conditioning system to manage refrigerant flow and help protect the compressor by separating liquid refrigerant from vapor before it returns through the HVAC circuit. This unit measures 3.500 inches in body diameter and 8.500 inches in body length, with a 5/8-inch male springlock inlet and a 3/4-inch male springlock outlet. The switch port diameter is 12.0 mm, and the assembly is built from steel for OE-style service replacement.

This part cross-references Gates 51545 and Hayden 3652 for the same application. If you are servicing a Ford E-150 Econoline, E-250 Econoline, or E-350 Econoline A/C system, Four Seasons 33099 provides the correct accumulator format for the listed 1994-1996 vehicles.

What It Helps Address

• Refrigerant pooling in the A/C system
• Compressor protection concerns caused by liquid refrigerant return
• Loss of proper accumulator function in aging Ford van HVAC systems
• Incorrect port style or fitting mismatch during A/C repair
• Failed accumulator housing on serviceable OE-style applications

Installation Notes and Tips

Verify the springlock inlet and outlet sizes before installation and confirm the switch port configuration matches the vehicle’s HVAC setup. Replace worn O-rings during service and inspect the surrounding A/C lines, seals, and mounting points before reassembly. Mounting hardware is not included, so reuse or source the required hardware separately as needed.

For best results, evacuate and recharge the system according to the vehicle service procedure after accumulator replacement. Confirm fitment against the specific Ford E-Series model and year before ordering, especially on 1994-1996 Ford E-150 Econoline and related van applications.
