Why does the Baojun 730 fan keep running?

[JustinLee]

Reasons why the Baojun 730 fan keeps running: 1. If you notice the radiator fan running immediately after turning off the engine, wait for a while. The water temperature in the radiator decreases slowly, and the cooling fan may continue to operate for some time before stopping as the temperature hasn't dropped yet. 2. If the fan continues to run even when the car has completely cooled down, there may be a fault in the cooling fan assembly or its wiring. The Baojun 730 is a family MPV product under SAIC-GM-Wuling Baojun, with body dimensions of 4780mm in length, 1820mm in width, and 1755mm in height, and a wheelbase of 2750mm. In terms of interior, the Baojun 730 still follows the beige and black color scheme, but with significant improvements in craftsmanship. The upgraded dashboard features wood grain panels and added chrome strip decorations.

I'm a car enthusiast and my Baojun 730 has been having this annoying issue where the cooling fan keeps running non-stop. Usually, this is related to engine temperature – for instance, a faulty coolant temperature sensor might send incorrect signals, making the car think it's overheating and thus continuously activating the fan. Another possibility is a stuck or aged relay that fails to shut off, keeping the fan running indefinitely. When diagnosing, first check the coolant temperature gauge on the dashboard. If it shows normal or mid-range readings, the sensor might be faulty. Then, listen to the fan noise – if it continues humming after the engine is turned off, it's likely an electrical issue. Low coolant levels are also a common culprit, as insufficient fluid can overload the system and cause the fan to run excessively. Ignoring these issues not only drains the battery but may also lead to engine overheating or even boiling over, which would be disastrous. I recommend first checking and topping up the coolant, then bleeding the system and test driving. If the problem persists, visit a professional repair shop for diagnosis. The fan system in the Baojun 730 is relatively simple, but proper routine maintenance can save you a lot of hassle.

I often work on cars, and if the Baojun 730's fan keeps running, don't panic. Start with the basics: check the coolant reservoir in the engine bay—if the level is too low, top it up immediately, and fix any leaks if found. Then, keep an eye on the dashboard; if the water temperature is high, pull over to let it cool down. If the fan still runs when the temperature is normal, try turning off the A/C, as the A/C compressor activates the fan. If the fan continues running after the engine is off, it might be a stuck relay—check the fuse box and try manually switching it. Another possibility is a faulty sensor; if it's dirty or broken, it may send false overheating signals. Use an OBD scanner to quickly check for error codes. Remember, prolonged fan operation accelerates component wear and drains the battery, which could leave you stranded if the car won't start after parking. For safety, if you notice the water temperature rising rapidly, slow down and pull over. There’s no shame in visiting a professional shop if you can’t fix it yourself.

I think the fan keeps running, mostly due to heat-related faults. The water temperature sensor may be sending abnormal overheating signals, preventing the fan from stopping; or the relay may have failed, causing a short circuit, which is common in the Baojun 730. Insufficient coolant is also a key point, easily causing the fan to be forced to work. It could also be triggered by the air conditioning system. If not addressed in time, it may damage the engine or battery. Operationally, turn off the engine and wait for the fan to stop, then check if the fluid level is normal. If there is no improvement, seek a technician promptly.

From experience, a constantly running fan poses significant risks. It drains the battery, potentially leaving the car unable to start after long trips; once the fan is damaged from overuse, major repairs can be costly. Overheating also increases the risk of engine damage. If the water temperature rises while driving, pull over immediately—never force the car to keep running. For the 730, check for coolant leaks, ensure the sensor is clean and free of debris, and test the relay for responsiveness. These simple steps can help you troubleshoot on your own. Regular maintenance of the cooling system, such as checking fluid levels every six months, can prevent issues before they arise. Safety comes first—address minor problems early to avoid bigger headaches.

As a car owner, be vigilant about regular maintenance if the fan runs constantly. The 730 fan system is controlled by temperature signals, so regularly clean the sensors to prevent false alarms; check and top up the coolant level every 5,000 km. In hot weather, the fan is more prone to malfunction, so monitor the water temperature changes while driving. Improper modifications, such as random wiring, can also trigger issues. It's recommended to install a Bluetooth OBD tool for real-time fault code monitoring. If the fan keeps running, it indicates a system abnormality—don't delay, get it checked at a shop immediately. Component aging is normal as the car ages, but careful attention can extend its lifespan.
