They deal with heat, pressure, vibration, and chemical exposure every time the engine runs. Over time the rubber hardens, the inner lining can weaken, and the outside can crack from the heat cycling. Clamps and fittings can also create stress points where hoses start to seep before they actually split. Short trips and long idle time can accelerate aging because the engine goes through more heat cycles without steady airflow. That repeated expansion and contraction ... read more
