Four Seasons A/C Receiver Drier P/N:33373
Keep your air conditioning system clean and dry with the Four Seasons A/C Receiver Drier, part number 33403, a steel filter drier that drops in as a direct-fit replacement across a wide range of 1980s-early-'90s applications — including the 1979-1991 Mazda RX-7, 1982-1985 Honda Accord, 1985-1988 Chevrolet Nova, 1983-1991 Mitsubishi Montero, 1980-1989 Toyota Celica and 1981-1990 Toyota Land Cruiser. See the Buyer's Guide tab for the full list of 38 covered vehicles and their engines.
This drier acts as a filter, removing moisture and contaminants from the A/C system — debris that cannot be cleared by flushing — which is why replacement is essential whenever the system is opened.
A leaking or "open" system can saturate the desiccant bag within a few hours, making the drier ineffective, so this unit should be replaced any time the system is serviced. Replacing the filter drier is also required to validate compressor warranty. Backed by over 50 years of mobile A/C experience from Four Seasons.
