Gates 51977 Molded Coolant Hose

The Gates 51977 is a precision-molded coolant hose engineered to deliver OEM-quality performance for engine cooling systems. This factory-molded hose is designed to fit specific applications, eliminating the need to source expensive dealer parts while ensuring a proper seal and secure installation.

Key Features:

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

Gates coolant hoses resist vacuum collapse, chemical coolants, and temperature extremes to keep your engine running reliably. Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal sealing performance.
