IMPORTANT INFORMATION
Always confirm the correct OEM part number, engine type, and machine serial number before ordering, as hose routing, diameter, and moulded shape may vary depending on engine configuration and production range. Worn or damaged radiator hoses can result in coolant leaks, overheating, pressure loss, or engine damage. Industry repair discussions also commonly recommend checking hose orientation, clamp positioning, and pulley clearance during installation to prevent premature wear or hose failure.
