What does it mean when the water tap symbol lights up on the car?

When the water tap symbol lights up on the car, it indicates the engine malfunction indicator light. This light signifies that there is an issue with the engine. If the engine malfunction indicator light comes on while driving, it is likely due to poor combustion in the engine, which can lead to problems such as engine knocking or carbon buildup. The engine status indicator is controlled by the engine control unit (ECU), which manages nearly all electrical components of the engine. Therefore, any malfunction will be displayed through the engine malfunction indicator light. Possible reasons for the engine light turning on include: 1. Faulty ignition coil; 2. Thermostat failure; 3. Malfunctioning catalytic converter; 4. Oxygen sensor issue; 5. Excessive carbon buildup in the electronic throttle body.
I drive quite a lot, and when that water faucet icon lights up, it usually means the engine coolant temperature is too high—basically, your car is overheating and at risk of engine damage. The most common cause is low coolant levels, which could be due to a system leak, a clogged radiator, or a faulty water pump. I've encountered this situation on the roadside before—I immediately pulled over, turned off the engine, and waited for it to cool down before checking the coolant reservoir. If the level is low, you can top it up with distilled water or coolant as a temporary fix, but don't rush to drive far to avoid high temperatures damaging the engine. By the way, regularly checking fluid levels and the radiator can prevent this—don't ignore it, your car will thank you. If you experience similar issues and notice abnormal dashboard lights, it might indicate a broader electrical problem—safety first is always the right call.
