How many liters of antifreeze does the Baojun 730 need?
2 Answers
Baojun 730 requires 4.7 liters of antifreeze. Antifreeze is a coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and protecting against scale and corrosion throughout the year. How to replace antifreeze: Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with a particular focus on the five-way hose. Antifreeze flows through the five-way hose and is then distributed to different parts of the car to function. If there is any leakage of antifreeze in this section, replace the hose or resecure the connection as needed. Drain the old antifreeze, then flush the liquid channels with clean water. Add water to the antifreeze reservoir and continue to pour water into the reservoir so that it flows continuously through the engine cooling system. Then, start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water flowing out of the reservoir will have a faint pink color. Continue adding water until the outflow is clean. Remember to remove the heater hose and drain the water from the heater core. Approximately one hour after draining, add new antifreeze through the radiator hose. Then, add another bottle of antifreeze to the antifreeze reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. At this point, the coolant level will drop slightly as air is expelled from the cooling system. Add more antifreeze until the level reaches the "MAX" mark on the reservoir.
As a longtime owner of the Baojun 730, I've gained quite a bit of experience with coolant replacement over the years. This model typically requires about 6 liters of coolant, but the exact amount depends on the specific procedure. For instance, during a complete flush and refill, you'll need to thoroughly drain the old coolant from the engine first – last time I did this, it took approximately 6.5 liters to fill up completely. If you're just topping up the system, 1-2 liters should suffice; avoid overfilling to prevent overflow that could cause electrical issues. I always check the MIN and MAX markers on the expansion tank during refills, ensuring the level stays between them. The Baojun 730's straightforward cooling system design makes DIY maintenance relatively easy, though I recommend changing the coolant every two years to prevent winter freezing or summer overheating. Proper maintenance ensures worry-free long-distance driving with both safety and reliability. Pro tip: Choosing a quality coolant brand matters – organic formulas offer good value while protecting engine components.
