Four Seasons A/C Refrigerant Discharge Hose P/N:66059
$79.99

Keep the high-side of your A/C system sealed and flowing with the Four Seasons A/C Refrigerant Discharge Hose 66059, an application-specific assembly that drops in as a direct-fit replacement for the 2004-2007 Cadillac CTS (see the Buyer's Guide tab for engine details). The discharge hose routes high-pressure refrigerant from the compressor toward the condenser; if the original line has cracked, chafed, or is leaking at a fitting, this assembly replaces it.

  • Double-wall barrier hose: constructed with double wall barrier hose compatible with R1234YF, R134A, or R12.
  • Crimp fitting connection: factory-style crimped end fittings for a secure connection.
  • Sealing hardware included: contains gaskets, o-rings, or seals to properly replace the product.
  • Application-specific design: engineered for the listed vehicle, backed by Four Seasons' decades of mobile A/C experience.

A worn discharge hose can show up as low refrigerant, oily residue at the connections, or poor cooling. Diagnose the source of the leak before replacing, and evacuate and recharge the system to the correct specification after installation.
