Move refrigerant back to the compressor and keep your A/C blowing cold with the Four Seasons A/C Refrigerant Suction Hose 66740, an application-specific suction line assembly that drops in for the 1998 Buick Century, 1998 Buick Regal, 1998-1999 Oldsmobile Intrigue, and 1998-2003 Pontiac Grand Prix. This is the low-pressure hose that carries low-pressure refrigerant vapor from the evaporator back to the compressor; a cracked, chafed, or leaking original bleeds off refrigerant and leaves the system unable to cool.

  • Double-wall barrier hose: constructed to be compatible with R1234YF, R134A, or R12 refrigerant.
  • Seals included: contains gaskets, o-rings, or seals to properly replace the product.
  • Crimp fitting connection for the line ends.
  • Application-specific design: engineered and tested for years of trouble-free operation, backed by Four Seasons' more than 50 years of mobile A/C experience.

If a failed or leaking suction hose is the cause of your weak cooling, this replaces it. Have the system evacuated and recharged to the correct specification after installation.
