Before you replace the hose, rule out a leak elsewhere in the system and a compressor fault, since either one can also leave you with warm air from the vents. Oily residue at the hose or its fittings, a damaged hose, or an A/C system that has stopped cooling can mean a discharge hose needs replacing.
It is a direct-fit replacement for the 2015-2020 Ford Mustang.
