Gates molded coolant hoses are manufactured to fit upper, lower, bypass, heater and other coolant applications with OEM-quality specifications, saving you time, costs, and energy from going to your OE dealer for radiator hose replacements. Approved for Marine applications. Gates' curved hose line is the most comprehensive line on the replacement market.

• Engineered to resist electrochemical degradation, the leading cause of hose failure.
• Pre-shaped to fit and to ensure perfectly sealed conditions.
• Aramid or rayon knit reinforcement (depending on the application).

​The primary cause of coolant hose failure is an electrochemical attack on the rubber compound in the hose. 

This phenomenon is known as electrochemical degradation or ECD. It occurs because the hose liquid coolant and engine/radiator fittings form a galvanic cell or “battery”.

This creates a chemical reaction which causes micro-cracks to form in the hose tube. Coolant seeps into these cracks or stryations and begins to break down the reinforcement.

This leads to hose failure and ultimately roadside breakdowns.
