Gates 51386 Premium Molded Coolant Hose

The Gates 51386 Premium Molded Coolant Hose is a factory-molded radiator hose engineered to provide reliable coolant flow in demanding engine environments. This lower radiator hose is precision-manufactured to OEM specifications, ensuring a proper fit and optimal performance for specific vehicle applications.

Key Features:

• EPDM tube construction with synthetic fiber knit reinforcement for superior durability
• Heat-, ozone-, and chemical coolant-resistant EPDM cover
• Engineered to resist electrochemical degradation (ECD), the leading cause of coolant hose failure
• Specifically-engineered materials resist vacuum collapse, reducing the need for internal springs
• Pre-shaped to ensure perfectly sealed conditions and proper fitment
• Temperature range: -40°F to +275°F (-40°C to +135°C)
• Meets SAE 20R4 EC Class D2 and DIN 73411 Class A requirements

Gates molded coolant hoses are designed to combat electrochemical degradation, which occurs when the hose, liquid coolant, and engine fittings form a galvanic cell that creates micro-cracks in the hose tube. This premium hose provides long-lasting service and helps prevent roadside breakdowns. Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal performance.
