Gates 23647 Lower Molded Radiator Coolant Hose

The Gates 23647 is a premium molded lower radiator coolant hose engineered with OEM-quality specifications for reliable engine cooling performance. This precision-molded hose is designed to provide a direct-fit replacement for specific cooling system applications.

Construction and Materials:

• EPDM (Ethylene Propylene Diene Monomer) rubber tube construction for superior durability
• Synthetic fiber knit reinforcement provides structural strength
• Heat- and ozone-resistant EPDM cover protects against environmental degradation
• 1.35-inch inside diameter at both ends ensures proper coolant flow
• 31.2-inch centerline length for precise fitment

Performance Features:

• Engineered to resist electrochemical degradation (ECD), the leading cause of coolant hose failure
• Specifically designed materials resist vacuum collapse, eliminating the need for internal spring reinforcement
• Pre-shaped and molded to ensure proper fit and perfectly sealed conditions
• Meets SAE 20R4 EC Class D1 specifications for automotive coolant hose applications
• Temperature range: -40°F to +275°F (-40°C to +135°C)
• Resistant to heat, ozone, and chemical coolants for long service life

Gates molded coolant hoses are manufactured to fit lower, upper, bypass, heater, and other coolant applications with the same quality standards used in original equipment manufacturing. This lower radiator hose provides reliable coolant transfer between the radiator and engine block, helping maintain optimal engine operating temperatures.
