    Fleetrunner® Straight Coolant Hose

    This resistant and flexible radiator hose is perfect for general use on straight or slightly bent connections in heavy-duty vehicles. Approved for Marine applications.

    • Resists cold water leaks thanks to an advanced EPDM tube that stays soft and pliable, even under adverse operating conditions.
    • Engineered to resist electrochemical degradation, the leading cause of hose failure.
    • Meets requirements of SAE 20R1, type EC, class D, standard wall.

    ELIMINATING ECD.

    When creating our moulded 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 engineered 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.

    Features and Benefits

    • High-performance, high-temperature resistant reinforcement.
    • 2-ply bias fabric construction to maximise flexibility and strength.
    • Temperature range from -40°C to +135°C.
    • Cover marked in one-inch increments to facilitate approximate cut lengths.
    • Caution: Do not use for fuel or oil transfer applications.
    • Note: For a maintenance-free connection, use PowerGrip® SB Clamps.

    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 deterioration. 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.
