Gates 51829 Molded Coolant Hose

The Gates 51829 is a precision-molded coolant hose engineered to deliver OEM-quality performance for automotive cooling system applications. This pre-shaped hose is designed to ensure perfectly sealed connections and reliable coolant flow in demanding engine environments.

Key Features:

• EPDM tube construction with synthetic fiber knit reinforcement for superior durability
• Engineered to resist electrochemical degradation, the leading cause of coolant hose failure
• Heat and ozone-resistant EPDM cover withstands harsh under-hood conditions
• Pre-shaped design ensures proper fit and sealed connections
• Temperature range: -40°F to +275°F (-40°C to +135°C)
• Meets SAE 20R4 EC Class D1 specifications for reliable performance

Gates coolant hoses are factory-molded to exact specifications for upper, lower, bypass, heater, and other cooling system applications. The advanced EPDM compound resists the electrochemical degradation that occurs when coolant, hose materials, and metal fittings create a galvanic reaction, protecting against micro-cracks and premature failure. Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal sealing.
