Keep the A/C system clean and dry with the Four Seasons A/C Accumulator, MPN 33048. It installs as a direct-fit replacement for a range of 1991-1993 Ford medium- and heavy-duty trucks, including the L8000F, L9000, LN7000, LN9000, LT9000, LTL9000 and LTS9000 — see the Buyer's Guide tab for the full list of applications and years.
The accumulator/filter drier acts as a filter, removing moisture and contaminants from the air conditioning system — contaminants that flushing cannot remove, which is why replacing the accumulator/filter drier is essential during service. Moisture absorption is handled by an internal desiccant bag; a leaking or "open" system can saturate that bag within a few hours, leaving the unit ineffective.
- Filters and dries: removes moisture and contaminants the system can't shed through flushing.
- Desiccant bag: absorbs moisture to help protect A/C components.
- Leak-free build: quality welds for a durable, leak-resistant design.
- Install-ready: necessary gaskets, o-rings and seal are included.
Produced in an ISO/TS16949 and ISO14001 certified facility and backed by over 50 years of Four Seasons mobile A/C experience. Replacement of the accumulator/filter drier is required to validate the compressor warranty and should be done anytime the system is serviced.
