Product Description and Features

The Four Seasons 65657 hose assembly is a liquid line hose designed for the Toyota Tacoma's air conditioning system. It is constructed from a combination of aluminum and rubber, providing both strength and flexibility to withstand high system pressures typical of R134-a refrigerant applications.

The assembly comes with fittings and a gasket to facilitate proper installation and secure connections. It features a 16 mm high side service port without a switch port and includes an orifice tube, which is essential for regulating refrigerant flow within the system. The suction end uses a flange type connection, and the hose assembly is an exact OE replacement, ensuring compatibility and reliable performance.

Common Applications and Issues Addressed

• Replacement of worn or damaged A/C refrigerant liquid hoses in Toyota Tacoma models
• Resolution of refrigerant leaks caused by cracked or deteriorated hoses
• Restoration of proper refrigerant flow and system pressure in high-pressure A/C systems
• Correction of poor HVAC cooling performance due to faulty liquid line components
• Prevention of contamination and system damage by maintaining sealed connections with included O-rings and gaskets

Installation Notes and Tips

When installing the Four Seasons Hose Assembly 65657, ensure the system is fully depressurized and evacuated before removal of the old hose. Verify that the green O-rings (part number 24606) are properly seated to prevent leaks. The 16 mm high side service port should be accessible for maintenance and refrigerant charging. Since this assembly does not include a bracket or switch service port, confirm existing mounting points and switch compatibility on the Toyota Tacoma. Proper torque specifications should be followed for fittings to maintain system integrity.
