Gates 52527 Molded Coolant Hose

The Gates 52527 is a precision-engineered molded coolant hose designed to deliver OEM-quality performance as a direct replacement for upper, lower, bypass, heater, and other coolant circuit applications. Pre-shaped for a perfect fit, this radiator hose eliminates the guesswork and trimming associated with universal straight hoses.

Key Features:

• EPDM Construction: EPDM tube with synthetic fiber knit reinforcement and a heat- and ozone-resistant EPDM cover for long-lasting durability
• Electrochemical Degradation (ECD) Resistance: Engineered with specialized compounds to resist ECD — the leading cause of coolant hose failure
• Vacuum Collapse Resistance: Specifically engineered materials resist collapse under vacuum, reducing the need for internal support springs
• OEM-Quality Fit: Pre-shaped to match factory specifications for a properly sealed installation
• 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 marine cooling system applications
• Limited Lifetime Warranty: Backed by Gates' standard limited lifetime warranty

Gates molded coolant hoses are factory pre-formed to ensure a secure, leak-free connection. Gates recommends replacing hose clamps each time a new coolant hose is installed to ensure a proper seal and maximum service life.
