Installation Notes
- This tensioner is designed for the timing belt system on classic VW Group models equipped with 1.8L and 1.8T engines.
- When replacing the tensioner, it is highly recommended to replace the timing belt and water pump as well – these are interference engines and timing belt failure can cause serious damage to valves and pistons.
- Before removal, locate the OE belt routing diagram 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.
- Ensure the tensioner mounting surface is clean and free of debris before installing the new unit.
- After installation, rotate the engine by hand to verify proper belt tension and alignment, then start the engine briefly and recheck.
