Four Seasons A/C Refrigerant Suction Hose P/N:66846
Four Seasons 55819 a/c refrigerant suction hose for the 2011 Ram 1500 and other vehicles is a suction line hose assembly that carries refrigerant on the low-pressure side of the A/C system.
Weak cooling, or oily residue at a fitting, can mean the suction hose is leaking, and a cracked or rubbed hose can sometimes be seen with the engine off. A leaking condenser, a failing compressor or a worn fitting seal can be behind these signs too, so find the cause before you buy a hose.
It also fits the 2009-2010 Dodge Ram 1500 and the 2011 Ram 2500. If your truck is not one of these, open the Buyer's Guide tab to check your exact model and engine.
In the box: this listing is one hose assembly, with gaskets, o-rings or seals included for the replacement.
