Four Seasons 66304 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.
- Engineered and tested for trouble-free operation, with over 50 years of mobile A/C experience behind it.
- Double wall barrier hose compatible with R1234YF, R134A or R12.
- Crimp fitting connection.
- Application specific design.
Oily residue at a crimped fitting, a damaged hose or an A/C that no longer cools can point to a failing line. Weak cooling also has causes outside the hose, so with the engine off, look over the hose and its fittings for residue, cracks or kinks, and leave pressure testing to a shop. If this hose is the cause, this assembly replaces it.
It fits the 2007-2015 Audi Q7 as well as the 2009-2010 Audi VW Touareg and the 2009-2010 Volkswagen Touareg.
