What does it mean when the temperature gauge light comes on?

The temperature gauge light coming on indicates a fault in the engine's cooling system, which fails to ensure proper cooling of the engine. When the temperature gauge light is on, it not only causes wear and tear on internal engine components but may even lead to cylinder scuffing. Therefore, it is crucial to identify the cause when the temperature gauge light illuminates. The primary reason for the temperature gauge light coming on is insufficient coolant in the car's radiator, which needs to be replenished promptly. Steps to replenish coolant: 1. Ensure the engine is in a cold state; 2. Open the hood, locate the engine's coolant reservoir, and unscrew the radiator cap counterclockwise; 3. Directly add the same specification of coolant to the radiator until the liquid level reaches the maximum mark; 4. After replenishing the coolant, simply close the radiator cap.
That day I had just exited the highway when the coolant temperature warning light suddenly came on, which gave me a scare. As a car owner, I knew this meant the engine was overheating, possibly due to low coolant levels or a faulty water pump. I immediately pulled over, turned off the engine, and waited for it to cool down, not daring to open the hood right away to avoid burns. Upon checking the coolant reservoir, I found it nearly empty, most likely due to a leak. I added some water as a temporary fix, but later at the repair shop, I discovered the hose had cracked from aging. If left unchecked, the engine could have been destroyed, leading to exorbitant repair costs. So, when the coolant temperature warning light comes on, it's definitely an emergency signal—pulling over immediately to check is crucial. Developing a habit of checking the coolant level monthly can save you a lot of trouble.
