Where Should Antifreeze Be Added?

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.
