Four Seasons 66633 a/c refrigerant discharge hose for the 2014-2016 Cadillac ELR and other vehicles is a discharge line hose assembly that carries refrigerant away from the compressor on the high-pressure side of the A/C system.
- Engineered and tested by Four Seasons, which has over 50 years of mobile A/C experience
- Contains the gaskets, o-rings or seals needed to replace the hose properly
- Double wall barrier hose, compatible with R1234YF, R134A or R12
- Crimp fitting connection
- Application specific design
Refrigerant leaking at the hose or its fittings, oily residue on the hose, or A/C that blows warm can mean the hose needs replacing. Warm air has several possible causes, so first look the hose and crimped fittings over with the engine off and cool for oil stains, chafing or kinks, and leave pressure testing to an A/C shop.
It fits the 2014-2016 Cadillac ELR, the 2011-2015 Chevrolet Volt and the 2011-2015 Cadillac Chevy Volt.
