Gates 25699 Molded Coolant Hose OEM Replacement Radiator Hose

The Gates 25699 is a factory-molded OEM-replacement coolant hose engineered to deliver reliable, long-lasting performance in automotive cooling systems. Pre-shaped to match original equipment specifications, this hose installs quickly and seals consistently without modification.

Gates molded coolant hoses are constructed with an EPDM tube, synthetic fiber knit reinforcement, and a heat- and ozone-resistant EPDM cover — a proven combination that resists the temperature extremes, chemical exposure, and vacuum collapse common in modern engine cooling systems.

Key Features:

• Factory-molded to OEM dimensions for a precise, drop-in fit
• EPDM construction resists heat, ozone, and chemical coolants including extended-life formulas
• Engineered to resist electrochemical degradation (ECD) — the leading cause of coolant hose failure
• Reinforced construction resists vacuum collapse, reducing the need for internal support springs
• Temperature rated from -40°F to +275°F (-40°C to +135°C)
• Meets SAE 20R4 EC Class D1 standards
• 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, leak-free connection. Trust Gates — a global leader in fluid power and power transmission products — to keep your cooling system running at peak performance.
