Can the car be driven when the water temperature reaches 100 degrees?

The car should not be driven when the water temperature reaches 100 degrees. The normal operating temperature is around 90 degrees. Continuing to drive at 100 degrees can cause boiling over and cylinder scuffing, severely damaging the engine. Below is additional information on abnormal high temperatures: 1. Common causes of abnormal water temperature include: coolant leakage, insufficient coolant, long periods without adding coolant, failure of the cooling system's fan preventing engine cooling, malfunction of the circulation water pump, damage to the water temperature sensor, or a faulty temperature gauge. 2. If abnormal water temperature occurs, pull over immediately. However, do not turn off the engine right away, as there are various reasons for high water temperature. Shutting down all functions may cause the temperature to remain excessively high, harming the engine. The correct approach is to idle the engine, open the hood, turn on the heater to dissipate heat quickly, and ensure the car is parked in a shaded area.
As someone who frequently tinkers with cars, I believe that reaching a water temperature of 100 degrees is no trivial matter. The normal operating temperature range for most vehicles is between 85 and 95 degrees Celsius. Once it hits 100 degrees, it indicates engine overheating. This could be due to insufficient coolant, a clogged radiator, or a malfunctioning fan, which prevents the system from effectively dissipating heat. Continuing to drive under such conditions can cause the engine to overheat excessively, leading to cylinder head deformation or gasket failure, resulting in costly repairs. I recommend pulling over immediately, turning off the engine, and waiting for it to cool down before checking the coolant reservoir to ensure proper fluid levels. If you absolutely need to move the car, adding some distilled water as an emergency measure is acceptable, but it's best to visit a professional repair shop as soon as possible to diagnose the root cause. Regularly inspecting the cooling system, including hoses and fan operation, can help prevent such dangerous situations. After all, engine overheating shortens a car's lifespan, and driving safety should always come first.
As an experienced driver with years behind the wheel, I know you can't take a 100-degree water temperature lightly. The normal operating temperature should stay around 90 degrees—anything above that means your car is sounding the alarm. Continuing to drive risks sending engine temperatures spiraling out of control, potentially melting or warping internal components and leading to major repairs or even breakdowns. Worse, extreme heat could trigger explosions or accidents, endangering lives. My experience shows that when the temperature gauge hits this point, pulling over immediately is critical—don't push your luck for convenience. Safety steps include turning on hazard lights, shutting off the engine to cool for at least 30 minutes, then checking coolant levels. If low, top it up with water temporarily, but avoid long drives—call roadside assistance or head to a repair shop for thorough inspection. Monthly cooling system checks during routine maintenance prevent these issues. Remember: Stopping to check is always wiser than pushing forward.
