Gates 51458 Premium Modular Coolant Hose Assembly

The Gates 51458 Premium Modular Coolant Hose is a precision-engineered OE-quality replacement hose designed for demanding automotive cooling system applications. This modular assembly coolant hose features integrated OE components for a direct-fit installation that saves time and ensures reliable performance.

Key Features:

• EPDM tube with synthetic fiber knit reinforcement and heat-resistant EPDM cover for maximum durability
• Specifically engineered materials resist vacuum collapse, eliminating the need for internal springs in most applications
• Advanced compound formulation resists electrochemical degradation (ECD), the leading cause of coolant hose failure
• Pre-shaped modular design includes essential integrated components such as hose branches, quick-connectors, sensors, or restrictors
• Meets SAE 20R3 EC Class D1 (under 25mm ID) and SAE 20R4 EC Class D1 (25mm ID and over) specifications
• Temperature range: -40°F to +275°F (-40°C to +135°C)
• Resistant to heat, ozone, and chemical coolants for extended service life

Gates modular coolant hoses provide extreme all-weather flexibility and superior performance compared to basic replacement hoses. The pre-shaped design ensures proper fit and perfectly sealed conditions, while the advanced EPDM construction delivers exceptional resistance to the harsh conditions found in modern cooling systems. Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal sealing performance.
