Gates 51463 Premium Modular Coolant Hose

The Gates 51463 Premium Modular Coolant Hose is an application-specific cooling system component designed to deliver OEM-quality performance and reliability. This modular hose assembly is manufactured to fit specific vehicle applications and includes integrated OE-style components such as hose branches, quick-connectors, sensors, and restrictors for a direct replacement installation.

Key Features:

• EPDM tube construction with synthetic fiber knit reinforcement for superior durability
• Heat- and ozone-resistant EPDM cover withstands harsh engine environments
• Engineered to resist electrochemical degradation (ECD), the leading cause of coolant hose failure
• Specifically-engineered materials resist vacuum collapse, eliminating the need for internal springs
• Temperature range: -40°F to +257°F (-40°C to +125°C)
• Meets SAE 20R3 EC Class D1 for hoses under 1" ID and SAE 20R4 EC Class D1 for 1" ID and over
• Includes OEM-exact integrated components for precise fitment

Gates modular coolant hoses are precision-manufactured to match original equipment specifications, ensuring proper coolant flow and optimal engine temperature regulation. The advanced EPDM compound resists chemical coolants and prevents the micro-cracking that leads to premature hose failure. Gates recommends replacing hose clamps each time a new coolant hose is installed for maximum system integrity.
