Gates 24551 Premium Molded Coolant Hose

The Gates 24551 Premium Molded Coolant Hose is a factory-molded, OE-quality replacement hose engineered to deliver reliable cooling system performance. This pre-shaped hose is manufactured to exact specifications for a precise fit, ensuring perfectly sealed connections in your vehicle's cooling system.

Advanced Construction:

• EPDM tube 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
• Factory-molded to OEM specifications for a perfect fit

Performance Specifications:

• Temperature range: -40°F to +275°F (-40°C to +135°C)
• Meets SAE 20R3 EC Class D1 standards for hoses under 1-inch ID
• Meets SAE 20R4 EC Class D1 standards for hoses 1-inch ID and over
• Approved for marine applications
• Suitable for coolant, water, and air applications

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. Gates' superior EPDM compound resists this degradation for longer-lasting performance and reduced risk of cooling system failure.

Installation Note: Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal sealing performance. Not for use in fuel or oil transfer applications.
