Are Engine Coolant and Antifreeze the Same Thing?

[LillianaFitz]

Engine coolant and antifreeze are the same thing, and their functions are: 1. To provide anti-corrosion protection for the engine's cooling system; 2. To prevent the water from boiling when the engine temperature reaches 100 degrees Celsius; 3. To prevent the formation of scale, thereby avoiding a reduction in the radiator's cooling efficiency; 4. To ensure the engine operates normally under low temperatures. The method for replacing antifreeze is: 1. Open the vehicle's engine hood, and you can see the coolant reservoir in the upper right corner; 2. Open the antifreeze plug under the radiator to drain the old antifreeze; 3. Add new antifreeze, tighten the cap, and the antifreeze replacement is complete.
