    Eliminating ECD.

    When creating our FleetRunner® coolant hose, we wanted to tackle the leading cause of hose failure: electrochemical degradation or ECD. This occurs when the hose, liquid coolant, and engine/radiator fittings form a galvanic cell or "battery," creating a chemical reaction that allows micro-cracks to form in the hose tube. Coolant seeps into these cracks or striations and breaks down the reinforcement, leading to hose failure and, ultimately, roadside breakdowns. We worked to engineer our EPDM coolant hose material compound with superior electrochemical resistance, so your Gates® coolant hoses will last longer and keep your engine systems running stronger.

    Inspecting Your Coolant Hose.

    As part of our Be System Part initiative, we recommend regularly inspecting your critical vehicle systems, including your cooling system and hoses, at around 60,000 miles. As your coolant hose begins to age, the constant transfer of chemical fluids will corrode your hose from the inside out. When inspecting your coolant hose, there are a few simple signs that it's ready for replacement:

    Press for Soft Spots. The radiator hose is naturally rigid, and any soft spots along the hose body indicates the inner material has begun to break down. Firmly press on the hose body to feel for potential deteriorations.

    Check the Ends and Fittings. Look for cracks around the hose end, especially near the hose clamps.

    Feel for Bulges. Run your hands along the hose body to feel for protruding materials, which indicate a rupture within the hose that will eventually lead to failure.
