Four Seasons A/C Refrigerant Suction Hose P/N:66018
Four Seasons 56618 a/c refrigerant suction hose for the 2005-2006 Buick Terraza and other vehicles 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 weak cooling or oily residue around a fitting, which you can look for with the engine off. These signs alone do not prove the hose is the problem; a leak at the compressor can produce the same weak cooling.
Other vehicles it fits include the 2005-2006 Pontiac Montana and the 2005-2006 Saturn Relay. If your car is not named here, look it up on the Buyer's Guide tab to see whether it and its engine are covered.
