How often should water be added to the Hyundai Elantra's radiator?

Water should be added to the Hyundai Elantra's radiator when it is empty or below the minimum level. The radiator is part of the car's cooling system, and the radiator in the engine's water cooling system consists of an inlet chamber, outlet chamber, main plate, and radiator core. Taking the Hyundai Elantra 2020 Manual Zhixuan Vitality model as an example, its body dimensions are: length 4610 mm, width 1800 mm, height 1450 mm, with a wheelbase of 2700 mm. The Hyundai Elantra 2020 Manual Zhixuan Vitality model is equipped with a 1.5L naturally aspirated engine, with a maximum power speed of 6300 rpm and a maximum torque speed of 4500 rpm.
When I first became a Hyundai Elantra owner, I used to wonder how often I should top up the water in the radiator. Later, I realized this was completely wrong: the radiator in modern cars is actually part of the cooling system, and it doesn’t contain plain water but antifreeze, or more professionally called coolant. Adding water directly can cause rust, blockages, and even engine overheating. My manual states that coolant should be replaced every 2-3 years or 50,000 kilometers, and the fluid level should be checked regularly—inspect the reservoir near the engine when the car is cold, and if it’s below the MIN line, top it up with the same type of antifreeze. Don’t wait for the car to give a warning; get into the habit of taking a quick look every month to avoid costly repairs. Remember, in an emergency, adding a small amount of distilled water is acceptable, but you must take the car to a service center afterward to replace it with fresh antifreeze—otherwise, you’ll only hurt your wallet.
