(You save)
Keep clean, dry refrigerant flowing to the compressor with the Four Seasons A/C Accumulator with Hose Assembly (MPN 56790). It installs as a direct-fit replacement for the 1999-2001 Jeep Grand Cherokee — see the Buyer's Guide tab for engine-specific coverage. On the suction side of the A/C system, the accumulator stores excess refrigerant, separates liquid from vapor, and uses an internal desiccant to pull moisture and contaminants out of the loop.
Filters and dries the system: acts as a filter by removing moisture and contaminants that cannot be cleared by flushing, which is why replacing the accumulator/filter drier is essential.
Desiccant absorption: a desiccant bag absorbs moisture; a leaking or "open" system can saturate the bag within hours, leaving the unit ineffective.
Durable, leak-free build: quality welds and high-quality desiccant support long-lasting, leak-free performance from an ISO/TS16949 & ISO14001 certified facility.
Ready to install: the necessary gaskets, o-rings, and seal are included for easy installation.
Replacing the accumulator/filter drier is required to validate the compressor warranty and should be done any time the system is opened for service. Backed by Four Seasons' 50-plus years of mobile A/C experience.
