Baojun 730 antifreeze replacement method: 1. Drain the old antifreeze and use an air gun or other methods to clean up the residual old antifreeze; 2. Add new antifreeze, and the liquid level should not exceed the warning mark on the storage tank. Antifreeze is a coolant with anti-freezing function, which can prevent the coolant from freezing and cracking the radiator or damaging the engine cylinder block when parking in cold winter. Baojun 730 is a 7-seater family car launched by SAIC-GM-Wuling, including two models: 1.5T CVT Fashion and 1.5T CVT Flagship. It features practical space, high safety, comfort, and rich configurations.
I used to handle the coolant replacement for my Baojun 730 myself quite often. First, make sure the car is parked, engine off, and completely cooled down to avoid burns. Pop the hood, locate the drain plug underneath the car—usually near the water pump—and place a bucket to catch the old coolant. Unscrew the plug to let the old coolant drain completely, then flush the system with water. Next, pour in new ethylene glycol-based coolant, diluted with water as per the recommended ratio—never use it undiluted. After topping it up, start the engine for a few minutes, turn on the heater to purge air bubbles, and finally check the fluid level to ensure it's correct. The process is straightforward, but remember to wear safety gloves and work in a well-ventilated area. Dispose of the toxic old coolant properly—never dump it to avoid environmental harm. Regular coolant changes prevent engine corrosion and extend your car's lifespan. This method has saved me a lot on repair costs over the years.
