What causes the high water temperature in Baojun 730?

[Muhammad]

Insufficient coolant in the vehicle. The coolant has reached its replacement cycle. Damage to the engine thermostat. Blockage in the vehicle's radiator circulation lines. Damage to the vehicle's radiator or fan. Any of the above issues can lead to excessively high engine water temperature, rendering the vehicle unusable.

Last time my Baojun 730 had a sudden temperature spike which scared me - turned out the fan wasn't working because the motor burned out. Also, there was significant coolant leakage causing low levels in the radiator. Sometimes the thermostat gets stuck closed, preventing water circulation for cooling. A broken water pump stopping coolant flow is another culprit. Radiator clogged with dust or debris is common too. A leaking cylinder head gasket letting gas into the system makes it run hotter. You must pull over immediately, turn off the engine, and activate hazard lights - never keep driving as it'll cause severe engine damage. I've tried topping up coolant as emergency measure, but best to get professional comprehensive inspection at a repair shop.

Last weekend, while driving my Baojun 730 uphill, the coolant temperature suddenly spiked to the red line. Upon checking, I found the coolant reservoir was empty—probably due to a minor leak I hadn't noticed. The fan wasn't working either, and the mechanic later diagnosed it as a faulty relay that needed replacement. Additionally, a stuck thermostat can cause similar issues by preventing coolant circulation. Clearing the radiator of clogged dead leaves also helped. My advice: stop immediately to check fluid levels—don't push your luck. Regular maintenance checks on the cooling system can prevent such headaches.
