Four Seasons A/C Suction and Liquid Line Hose Assembly P/N:65176
Keep refrigerant moving through your Ford's air conditioning with the Four Seasons A/C Suction and Liquid Line Hose Assembly 66819. It's an application-specific, direct-fit replacement for the 2013-2019 Ford Explorer (V6-3.5L) that combines the suction line and liquid line into one assembly. The liquid line carries high-pressure refrigerant toward the evaporator while the suction line returns low-pressure vapor to the compressor, so a cracked, corroded, or leaking original can interrupt A/C performance if the line is the cause.
Backed by Four Seasons' decades of mobile A/C experience, this is an application-specific, direct-fit replacement for the listed Explorer.
