Product Details

Gates Molded Coolant Hose line is engineered for upper, lower, bypass, heater, and other coolant routing needs using OE-quality specifications. For this application, the molded shape helps match the original hose path in the cooling system, which is important when replacing a lower radiator hose on a 1955-1957 Chevrolet Bel Air or a 1955-1957 Pontiac Laurentian. The EPDM material is commonly used in coolant service for its resistance to heat and coolant exposure.

Common Cooling System Issues It Can Address

• Cracked or split lower radiator hose
• Coolant leaks at a worn hose section
• Collapsed or misshaped hose routing
• Restricted coolant flow caused by hose deterioration
• Replacement of an aging molded hose during cooling system repair

Installation Notes and Tips

Verify hose routing, end diameters, and centerline length before installation. Inspect hose necks, clamps, and adjoining cooling system components for wear or corrosion before fitting the new hose. Confirm the hose is installed in the lower radiator position listed for the vehicle application and route it to match the original molded shape.

Quality Assurance
