Key Features:

• Constructed from durable EPDM (ethylene propylene diene monomer) rubber for superior heat and chemical resistance
• Synthetic fiber knit reinforcement provides strength and durability
• Heat and ozone resistant cover protects against environmental damage
• Re-engineered materials resist vacuum collapse, eliminating the need for internal springs
• Engineered with compounds that resist electrochemical degradation, the leading cause of coolant hose failure
• Temperature range: -40°F to +275°F (-40°C to +135°C)
• Meets SAE 20R3 EC Class D1 and SAE 20R4 EC Class D1 specifications

Gates Premium Modular Coolant Hoses are designed as direct-fit replacements that match OEM specifications, including any integrated components such as hose branches, quick-connectors, sensors, or restrictors required for proper installation and function. Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal performance and leak prevention.
