Tension needs to be maintained on any belts to ensure efficient performance; any energy will be wasted if the belt is too loose, and the belt could slip off the pulley. Maintenance is important to prevent a break down, or engine damage. The signs to look out for include rust bleeds, or the grinding noise of bearings seizing up.
