Gates 3610 Molded Coolant Hose Replacement Radiator Hose

The Gates 3610 is a precision-engineered molded coolant hose designed as a direct OEM-quality replacement for radiator and cooling system applications. Factory pre-shaped to match original equipment specifications, this hose installs quickly and seals reliably without modification.

Engineered with an EPDM tube, synthetic fiber knit reinforcement, and a heat- and ozone-resistant EPDM cover, the Gates 3610 is built to withstand the demands of modern engine cooling systems. The compound is specifically formulated to resist electrochemical degradation (ECD) — the leading cause of coolant hose failure — which occurs when the hose, liquid coolant, and metal fittings interact to form micro-cracks that lead to leaks and eventual hose failure.

Key Features:

• EPDM tube construction resistant to heat, ozone, and chemical coolants
• Synthetic fiber knit reinforcement for strength and vacuum collapse resistance
• Engineered to resist electrochemical degradation (ECD)
• Pre-molded shape for OEM-accurate fit and leak-free sealing
• Meets SAE 20R4 EC Class D1 standards
• Temperature range: -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 secure, long-lasting connection. The Gates 3610 is part of the most comprehensive molded coolant hose line available in the automotive aftermarket.
