Where to Add Radiator Coolant?
2 Answers
Radiator coolant is added to the car's expansion tank. Open the engine hood and locate the expansion tank, which is usually spherical in shape. Remove the tank cap and add the appropriate amount of radiator coolant. The optimal filling level is between the MAX and MIN marks. Here are some related details: 1. Replacement Cycle of Radiator Coolant: Radiator coolant is generally replaced every two years. 2. Radiator Coolant Should Not Be Mixed with Water: Adding water can affect the performance of the radiator coolant, lowering its boiling point and reducing its cooling effectiveness. It also raises the freezing point, making it prone to freezing in cold climates. Ordinary tap water contains various impurities and ions, which can form scale over time and cause blockages. In emergency situations, adding water may be unavoidable, but it is recommended to use purified water, preferably distilled water, and not to add too much. 3. Shelf Life of Radiator Coolant: When adding radiator coolant, always check the shelf life. Typically, radiator coolant has a shelf life of about two years. Expired products should not be used. Choose high-quality coolant that matches the original color of your car or a universal type. Different brands and colors of radiator coolant have varying formulations, and mixing them can cause reactions that reduce their effectiveness.
I remember when I drove older cars, the coolant (also called antifreeze) was added to the plastic tank next to the radiator. First, you park the car and let the engine cool for at least half an hour before starting to avoid burning yourself. Open the hood, find the container with a cap labeled "Coolant" or "Antifreeze"—don’t confuse it with the windshield washer fluid tank. Use a dedicated funnel to prevent spills when adding, and stop when the liquid level is between the upper and lower marks. Coolant protects the engine from freezing in winter and overheating in summer. It’s best to use the OEM type to avoid mixing different kinds. If the level keeps dropping, there might be a leak in the system—check the water pump or connections immediately. Make it a habit to check the coolant level regularly to keep your car running smoothly.
