Rubber coolant hoses are subject to constant thermal stress and should be inspected regularly for signs of bulging, cracking, splitting at connection points, or loss of flexibility. Replacing a worn or leaking hose promptly helps maintain cooling system efficiency and protects engine and supercharger performance. When replacing this hose, it is good practice to inspect surrounding hoses, clamps, and flanges for wear as well.
