Gates 12113 Molded Coolant Hose Replacement Radiator Hose

The Gates 12113 is a precision-molded replacement coolant hose engineered to deliver reliable, leak-free performance in engine cooling systems. Pre-shaped to OEM specifications, this molded radiator hose installs quickly and correctly without cutting or bending, ensuring a perfect fit and properly sealed connections.

Gates engineers this molded coolant hose with an EPDM (Ethylene Propylene Diene Monomer) tube and cover paired with a synthetic fiber knit reinforcement. This construction resists the heat, ozone, and chemical coolants that cause premature hose failure, and is specifically engineered to combat electrochemical degradation (ECD) — the leading cause of coolant hose failure in modern vehicles.

Key Features:

• Factory pre-molded shape for precise OEM-style fit
• EPDM tube and heat- and ozone-resistant EPDM cover
• Synthetic fiber knit reinforcement for strength and vacuum collapse resistance
• Engineered to resist electrochemical degradation (ECD)
• Temperature rated from -40°F to +275°F (-40°C to +135°C)
• Meets SAE 20R4 EC Class D1 requirements
• Direct OEM replacement — no cutting or trimming required

Gates is a global leader in automotive cooling system components, supplying both OEM production lines and the aftermarket with hoses built to the same exacting standards. The Gates 12113 molded coolant hose is an ideal replacement for upper, lower, or bypass hose applications where a pre-formed hose is required.
