It carries hot coolant between the engine and the cab heater core or other cooling system components on heavy-duty trucks. Unlike standard rubber hoses, the blue silicone construction handles higher temperatures, resists cracking, and stays flexible over time. Replace your heater hoses when you see swelling, soft spots, or leakage to prevent coolant loss and cab heating problems.
