Keep low-pressure refrigerant vapor flowing back to your A/C compressor with the Four Seasons A/C Refrigerant Suction Hose 66710. It installs as a direct-fit replacement for the 2008-2011 and 2013-2021 Lexus LX570 and the 2008-2011 and 2013-2021 Toyota Land Cruiser, restoring the suction-side path in your air-conditioning system.

  • Suction-side routing: carries low-pressure refrigerant vapor from the evaporator outlet back toward the compressor inlet.
  • Direct-fit replacement: made to fit the listed Lexus and Toyota applications, so it routes into place on the vehicle.
  • Sealed refrigerant path: helps re-establish a leak-free connection so the system can hold its charge.

An A/C suction hose can crack, chafe, or leak at its connections over time. Signs it may need replacing include a slow loss of refrigerant, weak or intermittent cooling, or an oily residue where the hose seats. If a failed suction hose is the cause, this replaces it; diagnose the system first, since low cooling can have other causes.
