Gates 65007 Premium Molded Coolant Hose

The Gates 65007 is a premium molded coolant hose engineered for reliable engine cooling system performance. Factory pre-shaped to fit upper, lower, bypass, and heater hose applications, this molded replacement hose installs with OEM-quality precision and provides a perfectly sealed connection without modification.

Constructed with an EPDM tube, synthetic fiber knit reinforcement, and a heat- and ozone-resistant EPDM cover, the Gates 65007 is built to withstand the demanding environment of modern engine cooling systems. The specifically engineered compound resists electrochemical degradation (ECD)—the leading cause of coolant hose failure—which occurs when the hose, liquid coolant, and metal fittings form a galvanic reaction that causes micro-cracks and premature breakdown.

Key Features:

• Pre-molded shape ensures OEM-quality fit and a perfectly sealed connection
• EPDM tube and cover resists heat, ozone, and chemical coolants
• Engineered to resist electrochemical degradation (ECD)
• Specially formulated materials resist vacuum collapse
• Meets SAE 20R4 EC Class D1 standards
• Temperature rated from -40°F to +275°F (-40°C to +135°C)
• Approved for marine applications
• Not intended for fuel or oil transfer

Gates recommends replacing hose clamps each time a new coolant hose is installed to ensure a proper, leak-free seal. Gates molded coolant hoses are part of the most comprehensive curved hose line available in the replacement market.
