Gates 12514 Engine Coolant Bypass Hose

The Gates 12514 is a premium molded engine coolant bypass hose engineered to deliver OE-quality performance and reliability. This factory-molded hose is precision-manufactured to fit specific vehicle applications, providing a direct replacement solution for your cooling system.

Key Features:

• Factory-molded, OEM-style design ensures proper fit and sealed connections
• EPDM tube construction with synthetic fiber knit reinforcement
• Heat, ozone, and chemical coolant-resistant EPDM cover
• Engineered to resist electrochemical degradation (ECD), the leading cause of hose failure
• Pre-shaped to fit modern, tighter-fitting engine compartments
• Temperature range: -40°F to +275°F (-40°C to +135°C)
• Meets SAE 20R3 Type EC Class D-1 specifications

Gates coolant hoses are designed to withstand the demanding conditions of modern engine cooling systems. The advanced EPDM compound resists the electrochemical degradation that occurs when hoses, coolant, and metal fittings create a galvanic reaction, preventing micro-cracks and premature failure. Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal performance.
