Keep moisture and debris out of your air conditioning system with the Four Seasons A/C Accumulator with Hose Assembly / A/C Refrigerant Suction Hose (MPN 55605). This unit combines the accumulator/filter drier with its refrigerant suction hose, and it drops in as a direct-fit replacement for the 1989-1993 Ford Thunderbird, 1989-1993 Mercury Cougar, and 1990-1993 Ford Cougar — see the Buyer's Guide tab for engine-level fitment.

The accumulator/filter drier acts as a filter, using a desiccant bag to pull moisture and contaminants from the system — debris that flushing cannot remove, which is why replacing this component is essential during service.

  • Filters and dries: Removes moisture and contaminants that circulate through the A/C system.
  • Desiccant absorption: A desiccant bag absorbs system moisture; a leaking or open system can saturate the bag within hours, making an old unit ineffective.
  • Durable build: Quality welds are designed for a leak-free assembly, produced in an ISO/TS16949 and ISO14001 certified facility.
  • Install-ready: Necessary gaskets, o-rings, and seal are included for easy installation.

Four Seasons notes that replacing the accumulator/filter drier is required to validate compressor warranty and should be done anytime the system is serviced. Backed by over 50 years of mobile A/C experience.

Frequently Asked Questions

What does this accumulator/filter drier do?

It acts as a filter, using a desiccant bag to remove moisture and contaminants from the A/C system — debris that cannot be cleared by flushing alone.

Which vehicles does MPN 55605 fit?

It is a direct-fit replacement for the 1989-1993 Ford Thunderbird, 1989-1993 Mercury Cougar, and 1990-1993 Ford Cougar. Check the Buyer's Guide tab for engine-level fitment.

Are installation seals included?

Yes. The necessary gaskets, o-rings, and seal are included for easy installation.

Why should I replace the accumulator when servicing the A/C?

Four Seasons states replacement is required to validate compressor warranty and should be done anytime the system is serviced, since a saturated desiccant bag becomes ineffective.

How quickly can a desiccant bag become saturated?

A leaking or open system can saturate the desiccant bag within a few hours, which makes an old accumulator/filter drier ineffective at absorbing moisture.
