Four Seasons A/C Refrigerant Discharge / Suction Hose Assembly P/N:55457
Keep refrigerant moving through your A/C system with the Four Seasons A/C Refrigerant Discharge / Suction Hose Assembly 66076. This line assembly routes refrigerant between the compressor and the rest of the system, and it drops in as a direct-fit replacement for the 2015-2017 Chevrolet Equinox and 2015-2017 GMC Terrain (see the Buyer's Guide tab for engine-level applications). If a cracked, leaking, or corroded original hose is behind lost cooling, this replaces it.
Combining the discharge (high-pressure) and suction (low-pressure) sides in one assembly, it carries refrigerant on its designed path so the system can transfer heat as intended. Install per the vehicle service procedure, then evacuate and recharge the system to specification.
