About the Four Seasons Hose Assembly Product Line

The Four Seasons Hose Assembly line focuses on providing complete hose assemblies tailored for HVAC systems. This product line ensures compatibility and reliability by combining high-quality materials and precise fittings. The 65319 hose assembly exemplifies this approach by integrating both suction and liquid line functions into a single, efficient component.

Detailed Product Description

The Four Seasons 65319 hose assembly is specifically engineered for use in Cadillac XT5, Chevrolet Blazer, and GMC Acadia models. Its aluminum and rubber construction offers a balance of strength and flexibility, essential for withstanding the pressures and temperature variations in automotive air conditioning systems. The P-nut fitting on one end and flange on the other provide secure, leak-resistant connections. This assembly supports both R134a and R1234yf refrigerants, making it suitable for modern A/C systems. Included gaskets and fittings ensure a proper seal, while the integrated service port facilitates routine maintenance without system evacuation.

Common Applications and Issues Addressed

• Replacement of worn or damaged A/C suction and liquid line hoses
• Resolving refrigerant leaks caused by cracked or corroded hose assemblies
• Upgrading HVAC components to support R134a and R1234yf refrigerants
• Restoring proper refrigerant flow and pressure in Cadillac XT5, Chevrolet Blazer, and GMC Acadia A/C systems
• Eliminating poor cooling performance due to compromised hose integrity

Installation Notes and Tips

Ensure the vehicle’s A/C system is fully evacuated before removing the old hose assembly. Verify compatibility with the specific make and model—Cadillac XT5, Chevrolet Blazer, or GMC Acadia—prior to installation. Use the included gasket and fittings to achieve a secure, leak-free connection. Avoid overtightening the P-nut fitting and flange to prevent damage. After installation, check for leaks and proper refrigerant pressure using the service port.
