Where is the antifreeze generally added?

Antifreeze is generally added to the car's radiator, also known as the cooling radiator, which is a key component of the vehicle's cooling system. The radiator's function is to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator to release the heat, and then returns to the water jacket to circulate, achieving temperature regulation. It is an integral part of the car engine. The full name of antifreeze is antifreeze coolant, meaning it is a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing and expanding in cold winter conditions, which could otherwise crack the radiator or damage the engine block or cylinder head. Many car owners believe that antifreeze is only used in winter, but in fact, antifreeze should be used throughout the year.
As a seasoned car enthusiast, I usually add coolant to the expansion tank in the engine bay, which is a translucent plastic container marked with Min and Max lines. After the engine has completely cooled down, open the cap and pour in the dedicated coolant until the level reaches near the Max line. Regularly check the coolant level and top it up when it's low—don't wait for a warning light. I recommend using the same brand of coolant as the original factory specification, either mixed according to the manual or using pre-mixed coolant for convenience. Never just add water as a quick fix, especially in winter, as it can freeze and crack the radiator, leading to system failure. After adding coolant, start the engine and let it run for a few minutes before turning it off to recheck if the level stabilizes. If it drops, add a bit more to ensure safety. Always perform this operation on a cold engine to avoid steam burns. During annual maintenance, replace the coolant to prolong engine life, prevent corrosion, and ensure worry-free driving.
As a family car user, the most common place to add antifreeze is the expansion tank under the front hood. I carefully pour the antifreeze when the engine is cold, watching the liquid level rise to the Max line before stopping. Never mix it with tap water or cold water to avoid damaging the cooling system in winter. After adding, I start the car for a few minutes to let the circulation balance the liquid level, which then stabilizes. Check the level every six months to prevent low levels from causing malfunctions—safety first. Buy matching-color antifreeze from reputable stores and pour it directly to save hassle. If you occasionally forget to add water, it's best to switch to antifreeze for engine durability, and keep the engine bay clean inside and out.
