Gates 51657 Premium Modular Coolant Hose

The Gates 51657 Premium Modular Coolant Hose is an OE-quality replacement hose engineered for specific cooling system applications. This modular hose assembly is manufactured to exact specifications and includes integrated OE components such as hose branches, quick-connectors, sensors, or restrictors as required for proper fit and function.

Key Features:

• EPDM tube with synthetic fiber knit reinforcement and heat-resistant EPDM cover
• Engineered to resist electrochemical degradation, the leading cause of coolant hose failure
• Re-engineered materials resist vacuum collapse for reliable performance
• Temperature range: -40°F to +275°F (-40°C to +135°C)
• Meets SAE 20R3 EC Class D1 (under 1" ID) and SAE 20R4 EC Class D1 (1" ID and over)
• Heat and ozone resistant construction for extended service life

Gates modular coolant hoses are designed as direct replacements for complex OEM assemblies, eliminating the need to source multiple components separately. Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal sealing.
