1. The following are the reasons for the Baojun 730 overheating: 1. Lack of coolant: Check if the coolant level is low and needs to be topped up. 2. Electric fan failure: If the electric fan does not turn on when the engine is hot, inspect the circuit, resistor, grounding wire, and the fan itself for issues. 3. Thermostat failure: Check if the thermostat is functioning properly. 2. Below is an introduction to the Baojun 730: 1. Space: The Baojun 730 CVT version features an ergonomically optimized design with a 2+3+2 seating layout. The second and third-row seats can be folded flat for different usage scenarios, providing both comfortable seating and ample, practical storage space. 2. Powertrain: The Baojun 730 CVT version is equipped with a "1.5T turbocharged engine + simulated 8-speed CVT transmission" powertrain combination. The engine has a rated power of 111kW and a maximum net torque of 250N·m.

I've been driving my Baojun 730 recently, and the coolant temperature warning light keeps coming on, which is quite worrying. Possible causes of overheating include insufficient coolant or leaks—check if the coolant reservoir level is too low or if there are cracks in the hoses, causing the coolant to drain away. Another reason could be a faulty fan motor that isn't spinning, or a radiator clogged with dust, preventing heat from dissipating. Alternatively, the thermostat might be stuck closed, disrupting coolant flow. Additionally, if the car is overloaded with passengers or climbing steep hills, the engine's increased workload can easily lead to overheating. If this happens, don't push it—stop immediately, open the hood to cool it down, and avoid risking engine damage. Get to a repair shop as soon as possible for part replacements. Make it a habit to check the temperature gauge before driving and regularly clean the radiator fins to ensure proper airflow.

As a seasoned driver with experience in over a dozen vehicle models, I've found that the Baojun 730 commonly experiences overheating due to aging cooling system components. Issues include thermostat blockage preventing water flow regulation, worn-out water pumps with poor circulation, broken fan wiring or relay failures causing slow or non-starting fans, and coolant contamination hindering heat dissipation. Regularly check the coolant's color and condition—replace if overly cloudy to prevent clogging. Overloading the vehicle easily raises temperatures, so reducing luggage and passenger count can help prevent this. Experience dictates not to delay addressing overheating; allow natural cooling after engine shutdown before inspection, prioritizing safe driving.

As a car enthusiast, I'm particularly interested in the high-temperature issues of the Baojun 730 engine. Possible causes include insufficient ventilation in the radiator design, accumulation of impurities blocking the fins; failure of the water pump preventing water circulation; and issues with the thermostat's opening and closing exacerbating the problem. Through experimentation, I've found that aftermarket modifications can increase engine load, such as installing audio systems that generate additional heat. Regularly cleaning external dirt from the radiator with a water gun and ensuring the fan operates correctly are crucial. Paying attention to engine health extends its lifespan and avoids the danger of breakdowns.
