Keep refrigerant moving through your air-conditioning loop with the Four Seasons A/C Refrigerant Suction Hose 66851. It drops in as a direct-fit replacement for the 2007-2009 Mazda 3, carrying low-pressure refrigerant vapor from the evaporator outlet back to the compressor inlet on the suction side of the system.

  • Suction-side routing: Channels low-pressure refrigerant vapor from the evaporator to the compressor, completing the return leg of the A/C circuit.
  • Application-specific replacement: A direct-fit hose for the listed 2007-2009 Mazda 3 application.
  • Replacement job: If the original hose is cracked, chafed, or leaking at a fitting and is the cause of lost cooling, this replaces it.

An A/C hose that leaks or restricts flow can bleed off refrigerant charge and reduce cooling. Signs this hose may need replacing include visible cracking or abrasion, oily residue at the crimped fittings, or a system that won't hold charge. Have the system diagnosed to confirm the leak point before replacing.
