What does the faucet symbol in the car mean?

[SanClaire]

The appearance of a faucet symbol in the car refers to the engine malfunction indicator light. The reasons for its illumination are: 1. Sensor issues: When the water temperature, crankshaft position, air flow, intake temperature, or oxygen sensors are damaged, have poor contact, or experience signal interruption, the car's ECU cannot accurately obtain engine data; 2. Maintenance issues: Irregular maintenance and poor driving habits can increase the burden on the engine; 3. Fuel quality issues: The fuel added to the car has specific grades, and failure to meet the required specifications can cause engine wear; 4. Poor fuel mixture combustion: This can lead to engine carbon buildup or knocking issues, which are detected by the engine's oxygen sensor; 5. False faults: Occurrences such as impacts during driving, tampering with certain engine connectors, or temporary ECU signal interruptions.

I noticed that faucet-like warning light on the dashboard while driving, which is actually the engine coolant temperature warning light. This usually indicates a problem with the engine cooling system - either low coolant level/leakage in the radiator, a broken cooling fan that's not spinning, or a stuck thermostat causing continuous coolant circulation. I remember last time my car had this issue, it turned out to be a leaking water pump. Continuing to drive could easily lead to engine seizure and complete failure. So never ignore this warning light - immediately pull over safely, turn off the engine and check the coolant reservoir. If it's low, you can temporarily top it up with purified water as an emergency measure, but arrange for a tow truck to take the vehicle to a repair shop as soon as possible.

That water temperature light looks like a faucet, right? It actually indicates a cooling system malfunction. Common causes include a clogged radiator, degraded or ineffective coolant, or aging pipe joints with leaks. I once experienced a blown fan fuse causing the temperature to skyrocket. In such cases, don't panic. After stopping the car, avoid opening the radiator cap immediately to prevent burns. Once the engine cools down, you can check if the coolant level in the overflow tank is too low. If it happens after a long-distance drive, it might also be due to insect remains clogging the radiator fins. Cleaning them might solve the issue.

The wrench symbol on the dashboard is the water temperature warning light, indicating engine overheating. Possible causes include a faulty thermostat failing to open the cooling circuit, damaged water pump impeller, or air bubbles in the coolant affecting heat dissipation. The most dangerous aspect is that it may lead to cylinder head gasket failure, with repair costs potentially exceeding tens of thousands. You must immediately stop the engine, open the hood for ventilation and cooling. Don't attempt DIY repairs - calling professional rescue services is the safest option. For regular maintenance, remember to periodically replace the coolant to prevent such issues.

I've studied this indicator, which is the abnormal water temperature warning light. Specifically, it could be due to a faulty thermostat valve stuck in the closed position, or scale buildup in the radiator causing poor circulation. In older cars, hardened or cracked rubber hoses can also suddenly leak coolant. When this happens, immediately turn off the air conditioning, pull over safely, and let the engine idle for a few minutes before shutting it off to prevent engine deformation. If you check the coolant and find it has turned cloudy, it likely indicates rust formation. Usually, minor repairs cost around two to three hundred yuan – definitely don't delay and let it turn into a major issue.
