Keep the rear air conditioning clean and dry with the Four Seasons A/C Receiver Drier 33566, a steel filter drier that services the rear A/C circuit. It's a direct-fit replacement for the listed applications, including the 1994 Dodge B150, B250 and B350, the 1995-1997 Dodge B1500, B2500 and B3500, and the 1994-1997 Ram 1500, 2500 and 3500 vans — see the Buyer's Guide tab for the full list.

  • Filters and dries: Acts as a filter, removing moisture and contaminants from the A/C system — debris that flushing cannot clear, which is why the drier is replaced during service.
  • Desiccant absorption: A desiccant bag absorbs system moisture; an open or leaking system can saturate the bag within hours and leave the drier ineffective.
  • Steel construction: Built with quality welds for a durable, leak-free design and high-quality desiccant for appropriate absorption.
  • Seals included: Ships with the necessary gaskets, O-rings and seal for easy installation.

Replacing the drier is required to validate compressor warranty and should be done any time the A/C system is opened for service. Backed by Four Seasons' decades of mobile A/C experience.

Frequently Asked Questions

What does this receiver drier do?

It acts as a filter, removing moisture and contaminants from the A/C system using a desiccant bag. These contaminants cannot be removed by flushing, so the drier is replaced during service.

Which vehicles does the 33566 fit?

It fits the rear A/C system of applications like the 1994 Dodge B150/B250/B350, 1995-1997 B1500/B2500/B3500, and 1994-1997 Ram 1500/2500/3500 vans. See the Buyer's Guide tab for the full list.

Does it come with the seals I need?

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

Do I need to replace the drier when servicing the A/C?

Replacement is required to validate compressor warranty and should be done any time the A/C system is opened or serviced, since a saturated desiccant bag leaves the drier ineffective.

What is it made of?

It is a steel filter drier with quality welds for a durable, leak-free design and high-quality desiccant for appropriate moisture absorption.
