Gates 23286 Premium Molded Coolant Hose

The Gates 23286 Premium Molded Coolant Hose is a factory-molded, pre-shaped radiator hose engineered to provide OEM-quality performance for specific vehicle cooling system applications. This precision-manufactured hose is designed to replace upper, lower, bypass, heater, or other coolant system hoses with an exact fit that ensures perfectly sealed conditions.

Key Features:

• Engineered to resist electrochemical degradation (ECD), the leading cause of coolant hose failure
• EPDM tube construction with synthetic fiber knit reinforcement and heat/ozone-resistant EPDM cover
• Pre-shaped design ensures proper fit and eliminates installation guesswork
• Temperature range: -40°F to +275°F (-40°C to +135°C)
• Meets SAE 20R4 EC Class D1 requirements
• Resists vacuum collapse, reducing the need for internal springs
• Approved for marine applications

Gates molded coolant hoses are built to combat electrochemical degradation, which occurs when the hose, liquid coolant, and metal fittings form a galvanic cell that creates micro-cracks in the hose tube. The engineered EPDM compound provides superior resistance to this chemical reaction, delivering longer service life and reliable engine cooling performance. Not intended for fuel or oil transfer applications. Gates recommends replacing hose clamps each time a new coolant hose is installed.
