What is the symbol for car water temperature warning?
2 Answers
The symbol for car water temperature warning is a thermometer with two wavy lines beneath it. When the water temperature warning appears, the driver needs to take immediate action by parking the car in a ventilated area and letting the engine idle to cool down. The sensor for the water temperature gauge is a thermistor-type sensor, which is fixed with threads on the engine's cooling water passage. The thermistor determines the current flowing through the coil winding of the water temperature gauge, driving the pointer to swing. Reasons for high car water temperature: 1. Dirty or clogged exterior or interior of the radiator; 2. Insufficient or leaking coolant; 3. Damaged thermostat; 4. Damaged water pump; 5. Damaged cooling fan or control system.
In the past when driving long distances, I often encountered the situation where the coolant temperature warning light came on, which left a deep impression on me. That indicator on the dashboard is shaped like a thermometer, usually flashing red to indicate the coolant temperature is too high. Possible causes include insufficient coolant, water pump failure, or radiator blockage, all of which could lead to engine overheating damage. I remember once on the highway when I didn't pull over in time, the engine ended up burning out, costing tens of thousands in repairs. Since then, I've learned to immediately pull over and shut off the engine to check the coolant level, topping it up when low. I've also developed the habit of checking monthly to ensure there are no leaks or aging in the cooling system. This little light may seem insignificant, but ignoring it carries too much risk, especially during hot summer days. Prevention is far more important than repair - only by ensuring safety can you drive with peace of mind.
