This replacement heater core upper hose outlet tube is among the highest quality replacements on the market! It connects from the water pump area and then goes along the RH inner fender wall then to the upper heater core tube on the firewall. After years of exposure to the elements, many tubes will develop small holes and then begin to leak. This part is designed to replace that leaking and rotted hose.


  • Replaces dealer part number: 10145142
  • Direct replacement for a weakend or leaking hose
  • Built to strict quality control standards
  • Correct for models with V6 3.1L
