1. Overheating: Water has a lower boiling point compared to engine coolant. When water is used alone in the radiator, it can reach boiling point more easily, especially when the engine is operating at higher temperatures. This can lead to overheating and potential engine damage.
2. Corrosion: Water can cause corrosion inside the engine components, including the radiator, water pump, and cylinder head. Over time, corrosion can weaken these parts and lead to leaks or more severe engine problems.
3. Lubrication: Engine coolant contains lubricants that help reduce friction and wear between moving parts within the engine. Water alone does not provide adequate lubrication, which can accelerate the wear and tear of engine components.
4. Freezing: In colder climates, water in the radiator can freeze during winter months. This can cause damage to the radiator and other engine components.
Therefore, it is crucial to use the correct engine coolant, which is specifically formulated to provide the necessary cooling, corrosion protection, and lubrication for the engine's optimal operation. Mixing the appropriate amount of coolant with water (according to the manufacturer's recommendations) or using a pre-mixed coolant is the best practice to ensure proper engine cooling and protection.
