Four Seasons A/C Refrigerant Liquid Hose P/N:56939
Four Seasons 66302 rear a/c refrigerant liquid hose for the 2007-2015 Audi Q7 and other vehicles is a liquid line hose assembly that carries refrigerant through the A/C system.
Oily residue at the fittings, a cracked or damaged hose, or A/C that blows warm can mean a leaking liquid hose. Before you replace this hose, rule out the condenser, the other lines and fittings, and a low charge from a leak elsewhere, since each of those can also leave the A/C weak.
This hose is a direct-fit replacement for the 2009-2010 Audi VW Touareg and the 2009-2010 Volkswagen Touareg, as well as the 2007-2015 Audi Q7.
