Four Seasons 66743 a/c refrigerant discharge / suction hose assembly for the 2005-2008 Buick LaCrosse and other vehicles carries refrigerant along the discharge and suction lines of the A/C system.

  • Engineered and tested for years of trouble-free operation, with over 50 years of mobile A/C experience behind it
  • Double wall barrier hose compatible with R1234YF, R134A or R12
  • Crimp fitting connection
  • Application-specific design

Weak cooling, oily residue around the hose or its fittings, or a refrigerant leak can mean this hose assembly needs replacing. These signs alone don't prove the hose is the problem, since a worn compressor can also cause weak cooling.

It fits the 2005-2008 Buick LaCrosse and the 2005-2008 Buick Allure.
