• minimizes the risk of noise and vibrations during engine operation,
• reduces wear on the accessory belt,
• ensures correct torque transfer to the water pump.

When replacing, it is recommended to check the condition of other components from the tensioners and rollers group, as well as the accessory belt, to avoid further service downtime.
