Coolant Water Hose

The main job of the cooling system is to dissipate heat in the air to prevent overheating of the engine, but the cooling system has other important functions. A car's engine runs best at moderately high temperatures. If the engine gets cold, it will accelerate component wear, reducing engine efficiency and emitting more pollutants. Therefore, another important role of the cooling system is to warm up the engine as quickly as possible and keep it at a constant temperature.
