Four Seasons A/C Refrigerant Liquid Hose P/N:66173
Four Seasons 56038 a/c refrigerant liquid hose for the 1999-2007 Ford F250 and other vehicles is a liquid line hose assembly that carries liquid refrigerant through the A/C system.
Oily residue on the hose or at its fittings, weak cooling and a system that keeps losing refrigerant can mean a worn liquid hose. These signs alone do not prove the hose is the problem, because a leak at the condenser or compressor can produce similar symptoms.
It fits a wide range of Ford models, including the 2000-2003 Ford F150 and the 1999-2007 Ford F-550 Super Duty. Open the Buyer's Guide tab and look up your exact model and engine before you order.
