Detailed Description

Febi 103323 is a radiator coolant hose designed for the engine-to-radiator coolant circuit. EPDM rubber is commonly used in cooling-system hoses because it handles heat, pressure, and coolant exposure well. This hose is specified for Audi A6 and Audi A6 Quattro fitments, making it a practical replacement when the original hose is cracked, softened, leaking, or no longer sealing properly. This part cross-references OE number 4F0 121 055 F for the same application.

Fitment

  • Fits 2006-2011 Audi A6, N/A. Notes: Material: EPDM (ethylene propylene diene Monomer (M-class) rubber); Connection Diameter: 45
  • Fits 2005-2011 Audi A6 Quattro, N/A. Notes: Material: EPDM (ethylene propylene diene Monomer (M-class) rubber); Connection Diameter: 45

What It Helps Fix

  • Coolant leaks from a cracked or deteriorated hose
  • Loss of coolant flow between the engine and radiator
  • Softening, swelling, or splitting in the original hose
  • Overheating caused by restricted or failing coolant hose routing
  • Seepage at the hose connection diameter interface

Installation Notes and Tips

Verify the hose routing, connection diameter, and OE reference before installation. Inspect adjoining clamps, necks, and coolant pipes for wear or corrosion so the new hose seals correctly. After installation, refill and bleed the cooling system according to the vehicle service procedure and check for leaks at operating temperature.

Quality Assurance

Febi supplies OE-style replacement parts for European vehicles, and this hose is built to match the specified cooling-system application for Audi A6 and Audi A6 Quattro models. Part number 103323 is identified for the listed fitments and OE cross-reference 4F0 121 055 F.
