Four Seasons A/C Refrigerant Suction Hose P/N:56809
Four Seasons 66603 a/c refrigerant suction hose for the 2004-2005 Toyota 4Runner is a suction line hose assembly that carries refrigerant back to the A/C compressor.
A leaking suction hose can show up as oily residue at the hose or its fittings, which you can see with the engine off, or as A/C that blows warm. A leaking condenser, a weak compressor or a failed seal at another fitting can be behind those symptoms too, so find the cause before you buy a hose.
This hose assembly is a direct-fit replacement for the 2004-2005 Toyota 4Runner.
