Gates 23898 Molded Coolant Hose

The Gates 23898 is a precision-molded coolant hose designed to provide OEM-quality performance for cooling system applications. This pre-shaped curved hose (Boyau Courbe) is engineered to fit specific vehicle applications with exact factory specifications, eliminating the need for costly dealership replacements.

Key Features:

• Engineered to resist electrochemical degradation (ECD), the leading cause of coolant hose failure
• EPDM tube construction with synthetic fiber knit reinforcement and heat-resistant EPDM cover
• Pre-shaped molded design ensures proper fit and perfectly sealed connections
• Resistant to heat, ozone, and chemical coolants for long-lasting durability
• Meets SAE 20R4 EC Class D1 specifications
• Temperature range: -40°F to +275°F (-40°C to +135°C)
• Engineered materials resist vacuum collapse, reducing the need for internal springs
• Approved for marine applications

Gates molded coolant hoses are manufactured to fit upper, lower, bypass, heater, and other coolant system applications. The specialized EPDM compound resists the electrochemical degradation that occurs when the hose, liquid coolant, and metal fittings create a galvanic reaction, preventing micro-cracks and extending service life. Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal performance.
