Keep moisture and debris out of your air conditioning system with the Four Seasons A/C Receiver Drier / Filter Drier (MPN 33276), a steel-bodied unit that also fits a wide span of older cars and heavy trucks. It's a direct-fit replacement for the listed applications, including the 1977-1982 Porsche 924, 1980-1983 BMW 320i, 1985-1988 Chevrolet Spectrum, 1982 Mazda 626, 1984-1991 Isuzu Trooper, and 1990-1994 Mack MS250P Mid-Liner — see the Buyer's Guide tab for the full list of 78 applications.
The receiver drier / filter drier protects the A/C system by capturing moisture and contaminants before they reach other components. A leaking or open system can saturate the desiccant within hours, so the drier should be replaced any time the system is opened or serviced. Signs it may need replacing include a saturated or contaminated system after a leak, repair, or component failure.
What does this receiver drier / filter drier do?
It filters the A/C system by absorbing moisture with a desiccant bag and trapping contaminants that circulate through the refrigerant — debris that flushing cannot remove.
Are seals and o-rings included?
Yes. The necessary gaskets, o-rings, and seal are included to help with installation.
What is it made of?
It is a steel filter drier, built with quality welds for a durable, leak-free design.
When should the drier be replaced?
It should be replaced any time the A/C system is opened or serviced. A leaking or open system can saturate the desiccant within a few hours, making the drier ineffective.
