Gates 23727 Molded Coolant Hose

The Gates 23727 Molded Coolant Hose is a premium replacement radiator hose engineered to deliver OEM-quality performance and reliability. This pre-shaped coolant hose is manufactured to fit upper, lower, bypass, heater, and other coolant system applications with precision specifications that match or exceed original equipment standards.

Key Features:

• EPDM rubber construction with synthetic fiber knit reinforcement for superior durability
• Engineered to resist electrochemical degradation (ECD), the leading cause of coolant hose failure
• Heat- and ozone-resistant EPDM cover protects against environmental damage
• Specifically designed materials resist vacuum collapse, reducing the need for internal springs
• Pre-molded to exact specifications for proper fit and perfectly sealed connections
• Meets SAE 20R4 EC Class D1 requirements for quality and performance
• Temperature range: -40°F to +275°F (-40°C to +135°C)
• Resistant to chemical coolants, heat, and ozone exposure

Gates coolant hoses are factory-molded to fit specific vehicle applications, eliminating the time and expense of visiting an OE dealership for replacement parts. The advanced EPDM material compound prevents electrochemical degradation by resisting the galvanic cell reaction that occurs between the hose, coolant, and metal fittings—preventing micro-cracks and premature failure. Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal performance and leak-free operation.
