The reasons for the thermometer light on the dashboard to illuminate are: 1. There is a fault in the engine's cooling system; 2. The engine lacks oil or water; 3. The antifreeze level is too low; 4. There is a leak in the engine; 5. Faulty AC relay or fan relay; 6. A blown fuse. Solutions for the thermometer light on the dashboard illuminating: 1. Open the engine hood and check the engine's working condition; 2. Check the water level and see if there is any leakage in the engine; 3. Check if there is a lack of antifreeze; 4. Inspect the engine's cooling system for any faults; 5. Check the AC relay, fan relay, and fuse for any issues.
My friend's car had this warning light come on before, so don't underestimate it. When the thermometer light on the dashboard illuminates, it usually indicates an issue with the engine cooling system, meaning the engine temperature is too high. Common causes include insufficient coolant, possibly due to a leaking radiator or long-term underfilling; a faulty cooling fan that can't dissipate heat; a non-functioning water pump preventing coolant flow; or a stuck thermostat that fails to open the cooling cycle. Sometimes, it could be a faulty sensor giving false readings. If this happens, the first thing to do is pull over and turn off the engine immediately—don't push it, or the engine could be severely damaged, leading to extremely expensive repairs. Check the coolant level; if it's low, you can add water as an emergency measure, but it's best to have a professional shop inspect it thoroughly. Regular maintenance checks on the cooling system can help prevent this issue.
