Four Seasons 56638 a/c refrigerant suction hose for the 2000-2005 Buick LeSabre and other vehicles is a suction and liquid line hose assembly that carries refrigerant between the components of the A/C system.
Oily residue at a fitting, lost refrigerant or weak cooling can mean this hose is worn or leaking, though the condenser or the compressor can be behind the same signs, so find the cause before you replace it. Cracks or chafing that you can see with the engine off are another sign.
It fits the 2000-2005 Buick LeSabre and the 2000-2005 Pontiac Bonneville.
The assembly arrives with gaskets, o-rings or seals for a proper replacement.
