Antifreeze should be added to the car's radiator. The car radiator, also known as the heat exchanger, is a key component in the vehicle's cooling system. Its 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 and regulate temperature. It is an integral part of the car engine. The antifreeze level should be between the max and min marks, which can be checked at the antifreeze reservoir. Generally, it is recommended to replace the antifreeze every 2 years, with a replacement volume of 4 to 5 liters. After replacement, the cooling system should be bled. Using waterless antifreeze can effectively reduce corrosion of the engine by the coolant, prevent scale formation, and extend the service life of the cooling system.

I have extensive experience in car repair. The coolant is usually added to the expansion tank in the engine bay, which is a transparent or semi-transparent plastic container marked with MIN and MAX indicator lines. Before adding, make sure the car is completely cooled down and the engine temperature has dropped, otherwise hot water vapor may spray out and cause burns. After opening the cap, slowly pour in the same brand and color of coolant, not exceeding the MAX line, and avoid mixing different types of coolant, such as different colors, as chemical reactions can damage the system. Remember to check the fluid level regularly, typically once a season, to prevent overheating issues caused by leaks. Once, I saw a novice add it to the wrong place, filling the windshield washer reservoir instead, resulting in the car overheating and breaking down on the road, wasting both time and money. Regular maintenance of the coolant, preventing freezing in winter and overheating in summer, ensures smoother engine operation.

As a car owner for many years, I'm used to adding coolant to the expansion tank. After opening the hood, look for that round plastic container with level indicator lines marked on it. Always wait until the engine cools down completely before handling - I got burned by hot steam once and it hurt for days. Pour the coolant slowly, neither too much nor too little, keeping the level between the mid and high marks. Just take a quick glance at it weekly to ensure the system works effectively. For daily commuting, maintaining a properly functioning cooling system saves a lot of hassle and reduces worries about roadside breakdowns. The maintenance is simple - just some basic knowledge can significantly extend your car's lifespan.

Learning car maintenance is quite interesting for young people. To add antifreeze, simply pour it into the engine's expansion tank. Look for a plastic container in the engine compartment marked with 'COOLANT' or a fluid level line, then open the cap and pour it in when the engine is cold. Use pre-mixed coolant and avoid exceeding the MAX line—keep the process simple. Check the fluid level monthly to prevent leaks and ensure system efficiency.
