Four Seasons 56997 a/c refrigerant discharge hose for the 2014-2015 Chevrolet Silverado 1500 and other vehicles is a discharge line hose assembly that carries refrigerant from the compressor toward the condenser.
- Engineered and tested for trouble-free operation, with over 50 years of mobile A/C experience behind Four Seasons.
- Double wall barrier hose compatible with R1234YF, R134A or R12.
- Crimp fitting connection.
- Application specific design.
Oily residue at the crimped fittings, rubbing marks or cracks on the hose, or an A/C that cools poorly can all point to a leaking discharge hose, though weak cooling has other causes too. With the engine off, look along the hose and its fittings for those marks before you buy, and leave any refrigerant testing to a shop.
This hose also fits the 2014-2015 Chevrolet Silverado 2500 and the 2014-2015 GMC Sierra 1500, among other trucks and SUVs. If your truck or SUV isn't named here, look up its year, model and engine in the "Vehicles it fits" section.
