Installation notes and tips
Confirm the hose path, end diameters, and overall formed shape before installation. Inspect the radiator neck, engine fitting, and clamps for wear or corrosion, and replace any damaged sealing surfaces before installing the new hose. Because this hose does not include a heat shield or protective sleeve, verify that nearby components do not create abrasion or excessive heat exposure.
Compatible with select vehicle cooling system applications, including Kenworth radiator hose replacement searches and other heavy-duty truck fitment needs. Use the vehicle’s original hose routing and dimensions to confirm the correct application for Dayco 72140.
