• Coolant leaks at the hose body or molded branch area
• Softening, swelling, or deterioration from heat and age
• Loss of proper coolant flow through the upper hose circuit
• Fitment problems caused by incorrect hose routing or shape

Installation Notes

Verify the hose routing, end diameters, and molded branch layout before installation. Inspect adjoining clamps, fittings, and mating surfaces for wear or corrosion, and confirm the cooling system is fully drained and refilled according to vehicle service procedures. For best results, compare the removed hose to Gates 51380 before final assembly.
