Can I Add Antifreeze by Myself Directly?

Antifreeze can be added by yourself, but you need to choose the same brand, model, and specification of antifreeze product, and add it appropriately based on the remaining antifreeze content in the engine. Antifreeze Replacement Cycle: For vehicles that run for long periods, such as taxis, high-quality antifreeze should generally be replaced once a year. For vehicles with shorter running times, it can be replaced every two years or every 30,000 kilometers. To prevent excessive foam formation, which reduces the heat exchange efficiency between the antifreeze and engine components, ensure the product is within its validity period when adding it. Long-lasting antifreeze can have a validity period of up to three years. If suspended matter, sediment, or deterioration/discoloration is found in the antifreeze, it should be replaced promptly, and the system should be cleaned. Antifreeze Replacement Method: Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with a focus on the five-way hose. The five-way hose gets its name from having five connection interfaces to various parts. Antifreeze flows through the five-way hose and is distributed to different parts of the car to function. If there is any leakage of antifreeze in this part, the hose should be replaced or the interface re-secured as needed. Drain the old antifreeze, then clean the liquid channels with water. Add clean water to the antifreeze reservoir, then continuously inject water into the reservoir to allow it to flow through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. The water initially flowing out from the reservoir will be slightly pinkish. Continue injecting clean water until the water flowing out is clear. Note: Remember to remove the heater hose and drain the water from the heater core.
I often add coolant to my car myself, thinking it's quite easy and can save some money. Open the hood, find the coolant reservoir with clear labeling. Make sure to do it when the engine is cold for safety. Choose the right type of coolant, like a 50/50 pre-mixed solution, and avoid mixing different colors. Pour it into the reservoir until it reaches the min-max level. Regularly check the fluid level and top it up when low. Coolant not only prevents freezing but also protects against rust and boiling, extending engine life. The tools needed are simple—just gloves and a bottle, and a jug of coolant only costs a few dozen bucks. Remember not to do it when the engine is hot, as the cooling system is under pressure and could spray out, causing burns. I check it every six months to keep my car healthy.
