Gates 24139 Premium Molded Upper Radiator Coolant Hose

The Gates 24139 is a premium molded upper radiator coolant hose engineered to deliver OEM-quality fit and long-lasting cooling system performance. Pre-shaped to match original equipment routing, this hose installs quickly and seals reliably without modification.

Built with EPDM rubber construction and reinforced with aramid or rayon knit fiber, the Gates 24139 is specifically engineered to resist electrochemical degradation (ECD) — the leading cause of coolant hose failure. ECD occurs when the hose, liquid coolant, and metal fittings form a galvanic cell that causes micro-cracks to develop in the hose tube over time. Gates' advanced compounding technology combats this from the inside out.

Key Features:

• Molded upper radiator hose with OEM-quality specifications for a precise, leak-free fit
• EPDM rubber construction resists heat, ozone, and vacuum collapse
• Engineered to resist electrochemical degradation (ECD), the leading cause of hose failure
• Pre-shaped design ensures correct routing and proper sealing at both ends
• Temperature rated from -40°F to +275°F (-40°C to +135°C)
• Part of Gates' comprehensive molded coolant hose line — the most complete on the replacement market

The Gates 24139 is a direct replacement upper radiator hose that eliminates the need for a dealer visit, saving time and money while delivering confidence-inspiring cooling system reliability.
