How to Read the Temperature on the Car's Water Temperature Gauge?
2 Answers
The 'C' on the water temperature gauge stands for the English word 'cold,' meaning cold, and 'H' stands for 'hot,' meaning heat. The 'water temperature gauge' includes numbers, temperature units, and a thermometer icon. The normal water temperature while driving should be around 90 degrees, slightly above the middle mark (the middle water temperature symbol is 85 degrees). Temperatures exceeding or falling below 90 degrees are abnormal. Here are the reasons for overheating: 1. Insufficient coolant: Coolant leakage can cause its temperature to rise. Check for coolant leaks; if found, repair the leaking pipes, etc. If not, promptly add the same brand of coolant. 2. Issues with the cooling fan: A faulty cooling fan can prevent heat generated during high-speed operation from being transferred to the antifreeze in time, affecting heat dissipation and causing the antifreeze temperature to rise, leading to boiling, etc. 3. Problems with the circulation water pump: If the water pump malfunctions, the water circulation on the engine's heat-conducting side cannot proceed normally, resulting in engine cooling system failure.
I've been driving for over a decade and frequently check the temperature gauge. It usually has a dial on the dashboard with C and H zones, representing cold and hot respectively. When starting the engine, the needle stays near C, and once the car warms up, it should settle in the middle zone, around 90 degrees, which is the optimal temperature for engine performance. If the needle moves past the halfway point toward H, say approaching the H line, it indicates overheating—possibly exceeding 100 degrees. In such cases, pull over immediately, turn off the engine, and inspect for issues like low coolant level, checking for leaks in the radiator or whether the fan is running. Longer warm-up times during cold winter starts are normal, but in summer, running the AC or climbing hills can raise the temperature, so keep an eye on the needle to prevent it from rising too high. Regular maintenance is crucial—check the coolant every six months. Overheating can damage engine components, such as blowing a head gasket, which can be a serious problem. Remember, make it a habit to glance at the temperature gauge while driving—safety first.
