Gates 25669 Molded Coolant Hose

The Gates 25669 is a molded engine coolant hose engineered to deliver OEM-quality performance in cooling system applications. Pre-shaped to match original equipment specifications, this hose provides a precise, leak-free fit and restores proper coolant flow between the engine and radiator.

Key Features:

• OEM-style molded design — pre-formed to match original equipment geometry for a direct, accurate fit
• EPDM construction — resists heat, ozone, and electrochemical degradation (ECD), the leading cause of coolant hose failure
• Fiber-reinforced walls — synthetic fiber knit reinforcement prevents collapse under vacuum and high-pressure conditions
• Temperature rated — engineered to perform from -40°F to +275°F (-40°C to +135°C)
• Meets SAE standards — manufactured to SAE 20R3/20R4 EC Class D1 specifications
• ECD-resistant tube — inner tube compound is specifically formulated to resist the electrochemical reactions that cause micro-cracking and premature hose failure
