Move refrigerant between the A/C system's high and low sides with the Four Seasons A/C Suction and Liquid Line Hose Assembly, MPN 65349. This suction & liquid line internal heat exchange hose assembly drops in as a direct-fit replacement for the 2020-2024 Cadillac CT4 and 2020-2024 Cadillac CT5 — see the Buyer's Guide tab for engine-level details. It routes low-pressure suction vapor back to the compressor and high-pressure liquid toward the evaporator, and is a common service part when a cracked, chafed, or leaking A/C suction line is causing lost refrigerant charge.

  • Double-wall barrier hose: constructed to be compatible with R1234YF, R134A, or R12 refrigerant.
  • Sealing hardware included: contains the gaskets, O-rings, or seals needed to properly replace the assembly.
  • Crimp fitting connection: the hoses use crimped end fittings.
  • Application-specific design: engineered and tested by Four Seasons, drawing on over 50 years of mobile A/C experience.

If a failed or leaking line is the cause of weak cooling, this assembly replaces it so the system can hold its charge again.

Frequently Asked Questions

What vehicles does this hose assembly fit?

It is a direct-fit replacement for the 2020-2024 Cadillac CT4 and 2020-2024 Cadillac CT5. Check the Buyer's Guide tab to confirm the exact application for your vehicle.

What does an A/C suction line do?

It carries low-pressure refrigerant vapor from the evaporator back to the compressor, while the paired liquid line routes high-pressure liquid refrigerant toward the evaporator.

Is any sealing hardware included?

Yes. The assembly contains the gaskets, O-rings, or seals needed to properly replace the product.

Which refrigerants is this hose compatible with?

The double-wall barrier hose is constructed to be compatible with R1234YF, R134A, or R12 refrigerant.

What are signs this line may need replacing?

Cracked, chafed, or leaking hose, oily residue at the fittings, and a loss of refrigerant charge. Diagnose the cause before replacing, as leaks can occur elsewhere in the system.
