Gates 52407 Molded Coolant Hose OEM Replacement Radiator Hose

The Gates 52407 is a precision-molded coolant hose engineered as a direct OEM-quality replacement for the vehicle's cooling system. Gates is a global leader in fluid power and power transmission products, and their molded coolant hose line is one of the most comprehensive replacement hose offerings available in the automotive aftermarket.

This hose features an EPDM rubber construction with synthetic fiber knit reinforcement and a heat- and ozone-resistant EPDM cover, providing long-lasting protection against the harsh conditions inside the engine bay. The compound is specifically engineered to resist Electrochemical Degradation (ECD) — the leading cause of coolant hose failure — which occurs when the hose, liquid coolant, and metal fittings form a galvanic cell that causes micro-cracking from the inside out.

Key Features:

• EPDM tube with synthetic fiber knit reinforcement and EPDM cover
• Engineered to resist electrochemical degradation (ECD)
• Heat and ozone resistant cover
• Re-engineered materials resist vacuum collapse
• Pre-molded to OEM shape for a precise, leak-free fit
• Meets SAE 20R4 EC Class D1 standards
• Temperature range: -40°F to +275°F (-40°C to +135°C)
• Approved for marine applications

Factory-molded to match exact OEM specifications, the Gates 52407 installs without modification and ensures a perfectly sealed connection. Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal performance and reliability.
