The coolant hose is vital because it transmits coolant from your engine and your radiator to other parts of the vehicle.
Coolant hose importanceThe coolant hose is important because it helps send coolant to the engine, and sometimes it transmits coolant to the water pump and prevents the engine from working too hard. The hose cools down the engine by moving fluid from the hottest part of the engine and recirculates the hot fluids to the radiator to start the cycle again. Without the coolant hose, the engine would not be able to function properly as it was made to do and it runs the risk of overheating.
