The Gates 23471 is a factory-molded OE-replacement coolant hose engineered to deliver reliable, leak-free performance in your vehicle's cooling system. With a 1.31 in. inside diameter and a pre-shaped lower radiator hose configuration, it installs with precision and seals perfectly without modification.

Key Features:

• Electrochemical Degradation (ECD) Resistance – Engineered with re-formulated materials to combat ECD, the leading cause of coolant hose failure, which occurs when coolant, metal fittings, and hose tube create a corrosive galvanic reaction
• Vacuum Collapse Resistance – Specially engineered materials resist vacuum collapse, reducing or eliminating the need for an internal spring in most applications (spring not included)
• Heat & Ozone Resistant Cover – Black outer cover is designed to withstand under-hood heat and ozone exposure for long-term durability
• Wide Temperature Range – Rated from -40°F to +275°F (-40°C to +135°C) for reliable performance in extreme conditions
• OEM-Quality Fit – Factory molded to match specific application geometry, ensuring a precise, properly sealed connection from radiator to pipe
• SAE Compliant – Meets SAE 20R4 and 20R3 Type EC Class D-1 and D-2 specifications
• Marine Approved – Approved for use in marine cooling system applications
• Sold Individually – Includes one lower radiator hose
• Lifetime Warranty – Backed by Gates' limited lifetime warranty
