• Compact Design: Its slim profile allows installation in tight engine bay spaces without compromising performance.
• Easy Installation: Equipped with standardized mounting bolts and a straightforward lever system, mechanics can replace or service the unit quickly.
• Compatibility: Designed for V‑ribbed (poly‑V) belts used in Audi, Skoda, VW, and other OEM engines, ensuring seamless integration.

Technical Specifications

Installation Guide

1. Preparation: Disconnect the battery and remove any components obstructing access to the belt tensioner.
2. Remove Old Tensioner: Loosen the mounting bolts, carefully detach the tensioner from the engine block, and release the belt from the pulley system.
3. Install New Unit: Position the APV2302 tensioner onto the mounting surface, secure it with bolts, and ensure the lever arm is correctly aligned.
4. Belt Re‑Installation: Route the V‑ribbed belt around the pulleys, using the tensioner's spring mechanism to maintain proper tension. Verify that the belt sits evenly on all grooves.
5. Final Checks: Tighten all fasteners to spec, reconnect the battery, and perform a test run to confirm smooth operation.

Maintenance Tips

• Inspect the tensioner for signs of wear or damage every 20,000 miles (or as recommended by the vehicle manufacturer).
• Check belt alignment regularly; misalignment can cause premature tensioner failure.
• Avoid over‑tightening bolts during installation to prevent stress on the spring mechanism.
• Keep the surrounding area clean and free of debris that could interfere with belt movement.
