What to Do When the Car's Water Temperature Is High While Driving?

Here are the steps to handle an overheated car engine: 1. Immediately pull over to a safe location. 2. Turn off the air conditioning system, open the engine hood, and let the engine idle. 3. Check the water temperature. If it is indeed too high, do not turn off the engine immediately. Shutting down the engine will stop the water pump, preventing the coolant from circulating, which can cause damage to the overheated engine. 4. Check the coolant level in the radiator. If the coolant is below the "min" line, add coolant promptly. If no coolant is available, you can temporarily use tap water or bottled water as a substitute. 5. Inspect the hoses and radiator for leaks. If there is a leak in the hose, the high water temperature may be caused by the leak. If the leak is minor and there is still plenty of water in the radiator, you can temporarily add purified water as an emergency measure and drive to the nearest 4S shop for inspection as soon as possible. 6. Check if the radiator fan is functioning properly. If the fan is not rotating normally, it might be stuck. Try to see if you can manually rotate the fan—it should move easily under normal conditions. If the motor and thermostat are functioning correctly, the issue might be a blown fan fuse, especially during summer when the car's electrical load is high.
When the engine temperature rises while driving, I immediately slow down and find a safe place to pull over, then turn off the engine to let it cool down. Overheating can cause the engine to expand, deform, or even be completely ruined, leading to costly repairs. Safety comes first. I open the hood, put on gloves, and check if the coolant is above the minimum line. If it's low, I add distilled water or specialized coolant, but never use regular water to avoid corroding internal components. If the fan isn't spinning or the radiator is clogged, I gently tap the fan to see if it starts working. This issue shouldn't be delayed—if not handled properly, it could make the next drive even more dangerous. During regular maintenance, I have the technician inspect the entire cooling system, including the water pump and thermostat. I also install a temperature monitor as a precaution against sudden issues. In short, if you notice a problem, stop the car immediately—don't push it. If necessary, call a tow truck or contact a repair shop.
