What It Does & How It Helps

Radiator and coolant hoses carry coolant between the engine, the radiator and the heater under full system pressure and temperature. Rubber hardens, swells and cracks with age, and the clamp areas are where most hoses fail first. A hose that bursts can empty the cooling system in minutes, so soft, swollen or cracked hoses are replaced before they strand the truck.
