Keep refrigerant moving on both the high- and low-pressure sides of your A/C system with the Four Seasons A/C Refrigerant Discharge / Suction Hose Assembly (MPN 55450). This application-specific assembly is a direct-fit replacement for the 1987-1989 Buick Century, 1987-1989 Chevrolet Celebrity, 1987-1989 Oldsmobile Cutlass Ciera, 1987-1989 Oldsmobile Cutlass Cruiser (all V6-2.8L), and the Pontiac 6000 (1987-1989 V6-2.8L; 1988-1991 V6-3.1L) — see the Buyer's Guide tab for the full list.

  • Combined discharge & suction line: routes high-pressure refrigerant from the compressor and returns low-pressure refrigerant on the suction side, in one application-specific assembly.
  • Double-wall barrier hose: aluminum/rubber construction; refrigerant type R134A.
  • Crimp fitting connections: UNF O-ring ends with a Female O-ring at both ends.
  • Ready to install: includes an inline muffler to dampen compressor pulsation noise and ships with the O-rings/seals needed for the connections.

The assembly does not include a mounting bracket or line fittings; transfer or replace those as directed by the vehicle service procedure. Signs the original hose may need replacing include refrigerant leaks, oily residue at the crimp fittings, and reduced A/C cooling. Diagnose the source of any leak before replacing. Manufacturer part number 55450.
