Four Seasons A/C Refrigerant Suction Hose P/N:66700
Route low-pressure refrigerant back to the compressor with the Four Seasons A/C Refrigerant Suction Hose 66839, an application-specific suction line assembly that drops in as a direct-fit replacement for the 2014-2018 Mazda 3 and 2014-2018 Mazda 3 Sport. This is the low-side hose that carries refrigerant vapor from the evaporator back toward the compressor, and a cracked, chafed, or leaking original is a common cause of lost cooling and low-charge conditions.
If a leaking or damaged suction line is the cause of your weak A/C, this replaces it. Have the system evacuated and recharged to the vehicle's specification after installation.
