Gates 24339 Premium Molded Coolant Hose

The Gates 24339 Premium Molded Coolant Hose is an OEM-quality replacement radiator hose designed to deliver reliable performance and long-lasting durability. This pre-shaped molded hose is engineered to fit upper, lower, bypass, heater, and other coolant applications with precision, eliminating the need for costly dealer replacements.

Key Features:

• EPDM tube with synthetic fiber knit reinforcement for superior strength and burst resistance
• Heat-, ozone-, and chemical coolant-resistant EPDM cover for extended service life
• Engineered to resist electrochemical degradation (ECD), the leading cause of coolant hose failure
• Specifically-engineered materials resist collapse under vacuum, reducing the need for internal springs
• Pre-shaped to ensure perfectly sealed connections and proper fit
• Temperature range: -40°F to +257°F (-40°C to +125°C)
• Meets or exceeds SAE 20R4 Class D2 and DIN 73411 Class A specifications
• Approved for marine applications

Gates molded coolant hoses feature precision factory molding to match OEM specifications exactly, ensuring compatibility and leak-free performance. The advanced EPDM compound resists the electrochemical reactions that cause micro-cracks and premature hose failure in standard hoses. Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal sealing and system integrity.
