Product Details

Gates Molded Heater Hose 12140 is a formed HVAC heater hose made for direct routing in confined spaces. The EPDM material is suited for coolant transfer, and the molded profile helps match the original hose path on applications such as the 2005-2008 Audi A4 and 2005-2008 Audi A4 Quattro, Pipe To Pipe. If you are replacing a worn or leaking heater hose on an Audi A4 or Audi A4 Quattro, this hose provides the correct molded layout and 16 mm end sizing for the listed applications. This part cross-references Carlson 13140 for the same application.

What It Helps Address

  • Coolant seepage from a cracked or aged heater hose
  • Improper hose routing in tight engine compartments
  • Heat-related hose hardening or collapse
  • Loss of heater circuit flow caused by a restricted hose
  • Fitment issues when a straight hose does not match the factory path

Installation Notes and Tips

Verify the hose routing, end diameters, and centerline length against the original part before installation. This molded heater hose is listed for pipe-to-pipe use on the specified Audi A4 and Audi A4 Quattro model years. Inspect adjoining pipes, clamps, and coolant connections for wear before reassembly, and confirm the cooling system is properly filled and bled after service.

Quality Assurance

Gates is known for OE-style hose construction, and this molded heater hose follows factory-style dimensions for the listed applications. The EPDM build and molded form support consistent fitment on the specified Audi A4 and Audi A4 Quattro vehicles.
