Four Seasons A/C Refrigerant Suction Hose P/N:65788
Four Seasons 66680 a/c refrigerant suction hose for the 2007-2011 Mazda CX-9 is a suction line hose assembly that carries refrigerant back to the compressor.
A leaking suction hose can show up as oily residue at the fittings, cracks or abrasion on the hose, or an A/C that cools poorly. Weak cooling alone does not prove the hose is bad, since a worn compressor can cause it too. A look at the hose with the engine off is a fair first step, and a shop can test the system for leaks.
It is a direct-fit replacement for the 2007-2011 Mazda CX-9.
