Common Repair Uses

• Restoring A/C moisture removal after compressor or system service
• Replacing a clogged or contaminated receiver drier
• Addressing poor cooling caused by restricted refrigerant flow
• Repairing a leaking A/C drier body or fitting seal area
• Servicing vehicles with a failed sight glass or switch-port drier assembly

Installation Notes

Verify the inlet and outlet fitting style, body dimensions, and switch-port configuration before installation. Replace O-rings and seals during service, evacuate the system, and recharge with the correct refrigerant and oil specification for the vehicle. Because the desiccant is not replaceable, the complete receiver drier should be replaced when contamination or moisture saturation is present.

Quality Assurance

Four Seasons 33403 is listed as meeting or exceeding OEM requirements for the specified applications. The steel construction, included desiccant, and OE-style fitment details support accurate replacement service for compatible Toyota, Mazda, Mitsubishi, Dodge, Honda, and Mercury HVAC systems.
