The symbol on the car dashboard that features a thermometer with two wavy lines beneath it is the coolant temperature indicator, commonly referred to as the temperature gauge. Function of the temperature gauge: It displays the temperature of the coolant inside the engine. When the needle of the temperature gauge points to 90 degrees, it indicates that the engine coolant has reached 90 degrees. The following are the hazards caused by excessively high or low engine temperatures: Overheating: First, check if there is insufficient coolant. If coolant levels are adequate, the issue might be due to clogged waterways or radiator, poor water pump performance, or problems with the electric fan system. If the actual temperature is not high, then the issue could be with the temperature sensor, wiring, gauge, or thermostat, requiring inspection and repair. Overheating can lead to engine cylinder scuffing and poor lubrication, resulting in wear of internal components. Low temperature: Low temperature conditions are rare and usually resolve automatically as the engine warms up. However, prolonged driving with low engine temperature prevents the engine from reaching normal operating temperature, leading to poor lubrication and significant wear on engine components.

I remember once driving on the highway when suddenly a red thermometer icon started flashing on the dashboard—that was the coolant temperature warning light. It meant the engine was overheating, and if not addressed promptly, it could cause serious engine damage. I was so scared that I immediately pulled over, turned off the engine, and waited for it to cool down. Upon checking the coolant level, sure enough, it was nearly empty. I topped it up with some temporary purified water and limped to the nearest repair shop. Turns out, this warning light usually indicates a cooling system issue, such as a leaking radiator or a faulty water pump. Safety first—if you notice abnormal coolant temperature readings, never push through. Continuing to drive risks engine seizure and could lead to an accident. Make it a habit to regularly check fluid levels and the cooling fan—prevention is always better than costly repairs.

The water temperature gauge symbol is the thermometer or water droplet-like icon on the dashboard, usually displaying in red when illuminated, indicating severe engine overheating. I frequently pay attention to such issues as they directly relate to driving hazards. Failure to address it promptly may lead to engine smoke, spontaneous combustion, or even costly major repairs. It's recommended to immediately pull over to a safe spot, turn off the engine for cooling, and check if the fan is functioning properly and the coolant level in the radiator. Possible causes include poor heat dissipation or coolant leakage. Regular maintenance can help minimize such troubles. Remember, this symbol may seem like a minor detail but concerns the lifeblood of your vehicle. Never ignore warning lights while driving—safety first is the golden rule.

The water temperature gauge symbol on the car is a thermometer-shaped icon, and a red light generally indicates that the water temperature is too high. As a novice driver, I was once puzzled by it, but later understood that it alerts to abnormal engine temperature. It could be due to insufficient coolant or a stuck fan, requiring immediate stopping to prevent engine damage. Simply put, it's the car's 'fever alert,' reminding you to promptly check the cooling system to prevent malfunctions, so you don't regret it only after something goes wrong.
