Keep cold air flowing and refrigerant sealed with the Four Seasons A/C Refrigerant Discharge / Suction Hose Assembly (MPN 66749). It routes high-pressure discharge and low-pressure suction refrigerant between the A/C system components, and it drops in as a direct-fit replacement for the 2013-2015 Cadillac ATS. Backed by decades of mobile A/C experience, this assembly is designed to replace a worn, leaking, or damaged original line.

  • Includes sealing hardware: ships with the gaskets, o-rings, or seals needed to properly install the assembly.
  • Double-wall barrier hose: constructed with double-wall barrier hose compatible with R1234YF, R134A, or R12 refrigerant.
  • Crimp fitting connection: uses factory-style crimped fittings at the ends.
  • Application-specific design: engineered for the listed application for a proper fit and routing.

Signs the original hose may need replacing include refrigerant leaks, oily residue at the fittings, or a system that no longer holds a charge. If a failed discharge/suction line is the cause, this assembly replaces it. For engine-level details, see the Buyer's Guide tab.
