What It Helps Address

• Coolant seepage at the pipe-to-housing sealing surface
• Loss of sealing integrity after coolant system service
• Leaks caused by a worn or flattened gasket
• Sealing issues during coolant pipe replacement on Audi A4 and Audi A6 models
• Recurring coolant odor or visible residue around the connection point

Installation Notes and Tips

Confirm the existing part number and match the vehicle application before installation. Clean the mating surfaces thoroughly so the steel gasket can seat evenly against the cast aluminium housing. Inspect the coolant pipe, flange, and surrounding sealing surfaces for corrosion, pitting, or damage before reassembly. Verify fitment for 2005-2008 Audi A4, 2005-2009 Audi A4 Quattro, 2005-2009 Audi A6 Quattro, and 2006-2011 Audi A6 prior to service.
