What does it mean when the water temperature warning light comes on?

[DiIsaac]

Here are the specific reasons and solutions for the water temperature warning light coming on: 1. The engine water temperature is too high. Solution: Stop the car to prevent engine damage from overheating. 2. High water temperature may also be caused by poor water circulation in the engine, preventing the temperature from dropping. Solution: Check the reason for poor water circulation and have it repaired by a professional mechanic. 3. The vehicle is low on coolant. Solution: Simply add coolant. 4. The cooling fan is not working. Solution: Check the relay and fuse, and after initial troubleshooting, have it repaired by a professional mechanic.
