Four Seasons A/C Accumulator with Hose Assembly,A/C Refrigerant Suction Hose P/N:55556
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.
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.
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.
