Gates 24939 Molded Coolant Hose

The Gates 24939 is a precision-molded coolant hose engineered to deliver OEM-quality performance in engine cooling system applications. Pre-shaped for a direct-fit installation, this radiator hose eliminates guesswork and helps ensure a leak-free, properly sealed connection every time.

Key Features:

• EPDM Construction: Tube, synthetic fiber knit reinforcement, and heat- and ozone-resistant EPDM cover for long-lasting durability
• Electrochemical Degradation (ECD) Resistance: Engineered to resist ECD — the leading cause of coolant hose failure
• Vacuum Collapse Resistance: Specifically engineered materials resist vacuum collapse, reducing the need for internal springs in many applications
• Wide Temperature Range: Rated from -40°F to +275°F (-40°C to +135°C)
• SAE Compliant: Meets SAE 20R4 EC Class D1 requirements
• Marine Approved: Approved for use in marine cooling system applications
• Pre-Shaped Fit: Factory molded to match OEM contours for a precise, secure installation

Gates recommends replacing hose clamps each time a new coolant hose is installed to ensure a proper seal. This hose is intended for coolant, air, and water applications only — not for use with fuel or oil.
