Keep your A/C system dry and protected with the Four Seasons A/C Accumulator with Hose Assembly / A/C Refrigerant Suction Hose 55609. It installs as a direct-fit replacement for the listed applications: the 1982-1985 Ford Thunderbird, 1983-1985 Lincoln Continental, 1984-1985 Lincoln Mark VII, 1989 Mazda MX-6, and 1982-1985 Mercury Cougar (see the Buyer's Guide tab for engine details).

The accumulator / filter drier sits on the suction side and acts as a filter, removing moisture and contaminants from the air conditioning system — contaminants that flushing cannot remove, which is why replacing the unit is essential during service.

  • Desiccant drying: Moisture absorption is handled by an internal desiccant bag; a leaking or "open" system can saturate the bag within a few hours and make the unit ineffective.
  • Leak-free construction: Quality welds are used for a durable, leak-free design, paired with high-quality desiccant for appropriate absorption.
  • Installation hardware: Necessary gaskets, O-rings and seal are included for easier installation.
  • Backed by experience: Produced in an ISO/TS16949 & ISO14001 certified facility, drawing on over 50 years of mobile A/C experience.

Replacing the accumulator / filter drier is required to validate compressor warranty and should be done anytime the system is serviced. This part is listed under both the accumulator-with-hose and suction-hose names.

Frequently Asked Questions

What does this accumulator / filter drier do?

It acts as a filter on the A/C suction side, removing moisture and contaminants from the system that cannot be cleared by flushing, which is why it is replaced during service.

Which vehicles does part 55609 fit?

It fits the 1982-1985 Ford Thunderbird, 1983-1985 Lincoln Continental, 1984-1985 Lincoln Mark VII, 1989 Mazda MX-6, and 1982-1985 Mercury Cougar. See the Buyer's Guide tab for engine details.

Are gaskets and O-rings included?

Yes. The necessary gaskets, O-rings and seal are included to make installation easier.

When should the accumulator / filter drier be replaced?

Four Seasons notes it must be replaced anytime the system is serviced, and replacement is required to validate the compressor warranty.

Why can't the desiccant just be cleaned instead of replaced?

Contaminants and saturated moisture can't be removed by flushing. A leaking or open system can saturate the desiccant bag within a few hours, making the unit ineffective.
