Four Seasons 66784 a/c refrigerant discharge hose for the 2007-2009 Hyundai Santa Fe and other vehicles is a discharge line hose assembly that carries refrigerant on the high-pressure discharge side of the A/C system.
- Double wall barrier hose compatible with R1234YF, R134A or R12
- Crimp fitting connection
- Application specific design
- Engineered and tested for years of trouble free operation, from a brand with over 50 years of mobile a/c experience
A leaking discharge hose can show up as oily residue at a fitting, a cracked or chafed hose, or an A/C that cools poorly. Weak cooling can start elsewhere in the system, so first look over the hose and its fittings with the engine off. A shop can leak-test the system for anything you can't see. If this hose is the cause, this assembly replaces it.
It also fits the 2007-2009 Hyundai Santa Fe / Santa Fe Sport / Santa Fe 7 as a direct-fit replacement.
