Product Details

Four Seasons Filter Drier 33430 is a direct-fit style A/C receiver drier for BMW 735i models from 1985-1986. The steel body measures 2.500 inches in diameter and 8.000 inches in length, with male insert O-ring fittings on both inlet and outlet sides. This unit uses a non-replaceable desiccant and is supplied with a sight glass, service port, and switch port for HVAC system service and inspection. Four Seasons 33430 is also referenced under several interchange numbers, including Bosch 16185 and Dayco 71167.

The Four Seasons Filter Drier line is used in automotive air conditioning systems where moisture removal and refrigerant cleanliness are critical. By filtering contaminants and absorbing moisture, this receiver drier supports stable A/C operation in the BMW 735i platform and other listed interchange applications.

What It Helps Address

  • Moisture in the A/C system
  • Contaminants circulating through the refrigerant path
  • Reduced cooling performance caused by a saturated drier
  • Service issues related to worn or leaking receiver drier connections
  • Inspection needs during HVAC diagnosis through the sight glass

Installation Notes and Tips

Verify the inlet and outlet fitting style, body dimensions, and port locations before installation. Replace the O-rings with the correct green seals supplied for the connection points, and confirm the service port and switch port alignment with the vehicle’s HVAC layout. This part fits 1985-1986 BMW 735i, N/A, and should be installed as part of a proper A/C system service after the system has been evacuated and inspected.
