Gates 23877 Premium Modular Coolant Hose Assembly

The Gates 23877 Premium Modular Coolant Hose is an engineered heater hose assembly designed to deliver OEM-quality performance for specific cooling system applications. This modular hose is manufactured with integrated components such as quick-connectors, branch fittings, and other essential OE-style parts to ensure a proper fit and reliable operation.

Key Features:

• EPDM tube construction with synthetic fiber knit reinforcement and heat-resistant EPDM cover
• Engineered to resist electrochemical degradation—the leading cause of coolant hose failure
• Specifically designed materials resist vacuum collapse, eliminating the need for internal support springs
• Temperature range: -40°F to +275°F (-40°C to +135°C)
• Meets SAE 20R3 EC Class D1 standards for hoses under 1-inch inner diameter
• Heat, ozone, and chemical coolant resistant construction
• Pre-shaped design ensures proper fit and sealed connections

Gates modular coolant hoses are built to match OEM specifications with precision-engineered components integrated into the assembly. This heater hose provides reliable coolant circulation while resisting the harsh operating conditions found in modern engine cooling systems. Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal performance.
