Four Seasons A/C Refrigerant Suction Hose P/N:66789
Four Seasons 66681 a/c refrigerant suction hose for the 2011-2015 Mazda CX-9 is a suction line hose assembly that carries refrigerant on the low-pressure side of the A/C system.
A leaking suction hose can show up as oily residue at the fittings or an A/C that cools poorly, though weak cooling can have other causes too. Before replacing the hose, look over it and its fittings with the engine off for oily residue, kinks or damage, and leave pressure testing to a shop.
This hose is a direct-fit replacement for the 2011-2015 Mazda CX-9.
Gaskets, o-rings or seals to replace the hose properly.
