Installation Notes

• This tensioner is designed for the timing belt system on Audi and VW models equipped with 2.0 TDI engines.
• When replacing the tensioner, it is highly recommended to replace the timing belt as well – if the belt fails, it can cause serious damage to valves, pistons, or the cylinder head.
• Before removal, locate the OE belt routing diagram under the hood or make a sketch of the belt path.
• Use appropriate tools to safely relieve spring tension – never cut or pry the belt off while under tension.
• Timing belt service is recommended every 60,000 miles; replacing the tensioner during timing belt replacement is critical for engine longevity.
• Ensure the tensioner mounting surface is clean and free of debris before installing the new unit.
• Torque mounting bolts to manufacturer specifications – verify appropriate torque for your specific engine application.
• After installation, rotate the engine by hand to verify proper belt tension and alignment, then start the engine briefly and recheck.
