Four Seasons A/C Suction and Liquid Line Hose Assembly P/N:56940
Four Seasons 66682 a/c suction and liquid line hose assembly for the 2010-2017 Mercedes-Benz E550 and other vehicles is an internal heat exchange assembly that carries refrigerant on the suction and liquid sides of the A/C system. It is also called an A/C suction line.
Warm air from the vents, oily residue around the fittings or a damaged hose can mean the assembly is leaking. Those signs alone do not prove this part is the problem, since a weak compressor can cause poor cooling too.
The vehicles it fits include the 2011-2014 Mercedes-Benz E500 and the 2012-2015 Mercedes-Benz C350, along with a wide range of other Mercedes-Benz models. Open the Buyer's Guide tab to check your exact model and engine.
The hose assembly comes with gaskets, o-rings or seals for replacing it properly.
