What icon is displayed when the water tank is empty?

There is no specific warning light for an empty water tank. Here is relevant information: 1. When the water tank runs dry, it usually causes overheating, which triggers the coolant temperature warning light. This warning symbol resembles a thermometer. When this light illuminates on the dashboard, it indicates the coolant temperature is too high, possibly due to insufficient water in the radiator. 2. As a crucial component of the liquid-cooled engine's cooling circuit, the radiator absorbs heat from the engine block to prevent overheating. Since water has a high specific heat capacity, its temperature doesn't rise significantly after absorbing engine heat. The engine's thermal energy is transferred through the liquid cooling circuit using water as a heat carrier, then dissipated via large cooling fins through convection to maintain optimal operating temperature.
When the coolant runs low, a red warning light shaped like a thermometer submerged in water or a kettle-shaped icon typically appears on the dashboard – this indicates insufficient coolant. Having driven for over a decade, I've encountered this situation several times. The first time I saw that light, I mistakenly thought it was an air conditioning issue, only to later realize the coolant reservoir was nearly empty. If not addressed promptly, the engine may overheat and stall, so whenever I spot this icon, I immediately pull over to check the fluid level. It's advisable to regularly inspect the coolant level, especially before long-distance trips, just in case. Additionally, keeping a bottle of antifreeze in the car is quite practical for emergency top-ups. Remember, safety comes first – don't let a small icon lead to major trouble.
