- Helps prevent damage to other accessory components

Setup, Compatibility & Care
Compatibility is strictly limited to select Fiat, Alfa Romeo, and Lancia models utilizing the 0.9 TwinAir engine configuration. Before installation, use a serpentine belt tool to relieve pressure on the existing tensioner to safely remove the old belt. When installing the T39346, ensure the mounting surface is clean and free of debris. Always verify that the belt is correctly seated in the ribs of the pulleys after the new tensioner is bolted into place. Periodically check the tensioner for any signs of grease leakage or play in the pulley bearing as part of your routine engine maintenance schedule.
