Detailed Description

Four Seasons part number 63176 is an A/C refrigerant discharge and suction hose assembly engineered for vehicles that require this exact hose configuration. It uses a P-nut fitting on one end and a flange on the other, with the hose assembly built around aluminum and rubber materials to handle HVAC routing demands. The included service port and gasket or seal support proper system connection, while the muffler is part of the assembly design. This part cross-references Monroe Shocks & Struts (e.g., 212870, 39149942) for the same application. Fits 2021-2025 Buick Envision, N/A.

Common Uses

  • Replacing a leaking or damaged A/C refrigerant hose assembly.
  • Restoring refrigerant flow through the discharge and suction line circuit.
  • Addressing service port or seal-related HVAC connection issues.
  • Replacing a hose assembly with the correct fitting style and refrigerant compatibility.

Installation Notes

Verify end types, refrigerant type, and service port configuration before installation. Confirm the vehicle uses a discharge and suction line assembly with a P-nut fitting and flange connection. Match the application to part number 63176 and the listed Buick Envision fitment before replacing the original hose.
