The Gates 24649 Premium Molded Coolant Hose is a factory-molded, OEM-quality replacement hose designed to deliver reliable cooling system performance. This pre-shaped hose is engineered to fit specific upper, lower, bypass, heater, and other coolant applications with exact manufacturer specifications, eliminating the need to visit your OE dealer for replacement parts.

Key Features:

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

Gates Premium Molded Coolant Hoses feature advanced EPDM compounds that prevent micro-cracks caused by electrochemical reactions between the hose, coolant, and metal fittings. This superior resistance to degradation ensures longer hose life and helps prevent unexpected cooling system failures. Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal sealing performance.
