Gates 24404 Premium Molded Coolant Hose

The Gates 24404 Premium Molded Coolant Hose is a factory-molded replacement radiator hose engineered to deliver OEM-quality performance for upper, lower, bypass, heater, and other coolant system applications. Manufactured with precision to match original equipment specifications, this pre-shaped hose ensures a proper fit and perfectly sealed connections in your vehicle's cooling system.

Advanced Construction and Materials:

• EPDM (Ethylene Propylene Diene Monomer) tube and cover construction
• Synthetic fiber knit reinforcement for superior strength
• Heat and ozone resistant cover protects against under-hood conditions
• Re-engineered materials resist vacuum collapse, reducing the need for internal springs
• Engineered to resist electrochemical degradation (ECD), the leading cause of coolant hose failure

Technical Specifications:

• Temperature rating: -40°F to 275°F (-40°C to 135°C)
• Meets SAE 20R4 and 20R3 Type EC Class D-1 and D-2 specifications
• Approved for marine applications
• Pre-shaped molded design for application-specific fit

Gates coolant hoses are designed to withstand the harsh chemical environment inside modern cooling systems. The specialized EPDM compound resists the electrochemical degradation that occurs when coolant, hose material, and metal fittings create a galvanic reaction, preventing the micro-cracks and striations that lead to premature hose failure. This ensures longer service life and reliable cooling system performance.

Note: Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal sealing and performance.
