Can the car still be driven when it overheats?

When the car overheats, it should not be driven. The vehicle should be turned off immediately to prevent further damage and avoid issues such as hose bursts or engine damage. If the temperature gauge lights up, it indicates that the engine coolant temperature is too high, warning the owner of potential engine damage. In this case, the vehicle should be pulled over as soon as possible, and the engine should be shut off. Do not attempt to restart the vehicle. Causes of engine overheating: 1. Insufficient coolant in the engine: Leaks in the engine cooling system can lead to a lack of coolant, causing the engine temperature to rise. 2. Thermostat failure: If the thermostat becomes stuck and fails to open the main cooling circuit in time, it can trigger the temperature warning. 3. Water pump damage or belt breakage: The water pump is responsible for circulating coolant into the radiator. If the water pump fails or the belt driving it breaks, coolant cannot flow into the radiator for cooling, resulting in excessively high engine temperature.
If your car's temperature is running high, I strongly advise against continuing to drive. With over 30 years of driving experience, I've seen too many cases where people ignored the overheating warning and completely ruined their engines. When the temperature gauge hits the red zone, it means there's a cooling system failure—possibly a broken fan or a leaking radiator. Continuing to drive can cause internal engine metals to expand and warp, pistons to seize, and in severe cases, smoke or even fire, endangering lives. I've personally handled several incidents where stubborn drivers pushed their cars to the repair shop, only to face repair bills exceeding tens of thousands. It's far better to pull over safely, turn on hazard lights, and call for help. Always develop good habits: check coolant levels before trips and clean the radiator regularly—these simple maintenance steps can prevent major issues. In short, safety comes first. If overheating occurs, stop immediately, turn off the engine, and wait for assistance. Ignoring it risks harm to yourself and others.
When the car overheats, it's best to stop driving immediately. As someone who enjoys playing with and repairing cars, I know this is the wisest choice. Engine overheating can cause rapid damage to internal components, such as cylinder liner deformation or cylinder head gasket burnout, and the repair costs can be significant, ranging from thousands to tens of thousands of yuan. Insufficient coolant is a common cause, possibly due to radiator cracks or water pump failure. Continuing to drive can cause the temperature to skyrocket, and in severe cases, the engine may smoke and stall, which is extremely dangerous. When I first started driving, I made the foolish mistake of continuing to drive to work despite the high temperature, only to break down halfway and get towed away, wasting both time and money. I recommend regularly checking the cooling system, using high-quality antifreeze, and stopping to inspect or calling the insurance company if any abnormalities are detected. Simply put, don't gamble with luck—prioritizing safety and saving money is the right way to go.
With years of experience in auto repair, I always advise owners against driving when their car overheats. When the dashboard's red warning light comes on, it indicates excessive temperature. Continuing to drive can cause engine damage, such as cylinder block deformation or cracked coolant pipes leading to severe fluid leakage. The causes are often simple issues like a clogged radiator or a non-functioning fan, but forcing the car to run could result in massive repair costs. Regular maintenance is crucial—periodic coolant replacement and component cleaning can prevent overheating. If overheating occurs, the safest approach is to pull over, turn off the engine, and seek professional assistance immediately.
