Installation Notes

Verify the vehicle’s year, model, and lower hose routing before installation. Compare the existing hose shape, connector style, and branch layout to the replacement part number 51485. Inspect mating surfaces, clamps, and adjacent cooling-system components for wear or contamination before reassembly. Because this is a molded, application-specific hose, correct routing is important to maintain clearance and connection alignment on Mercedes-Benz Sprinter 2500, Sprinter 3500, and Sprinter 3500XD models.
