Common Problems This Hose Can Address

  • Restricted coolant flow caused by a deteriorated hose assembly
  • Fitment issues when a straight universal hose is not the correct shape

Installation Notes and Tips

Verify the vehicle year, make, model, and heater-to-engine routing before installation. Compare the original hose shape, branch layout, and end diameters to the replacement part number 22946 to confirm proper alignment. Inspect adjoining coolant system components, clamps, and connection points for wear or residue before refilling the system.
