It’s used in heavy-duty truck cooling systems to carry hot coolant between the engine, radiator, and heater core. Silicone hoses last longer than standard rubber hoses under high heat and pressure, making them a common upgrade during cooling system repairs or preventive maintenance. You would replace it if the original hose is swollen, cracked, or leaking.
