How to Read the Volkswagen Jetta Water Temperature Gauge?

[Young]

To read the Volkswagen Jetta water temperature gauge, follow these steps: 1. The temperature scale ranges from C to H, where C represents 60 degrees Celsius. Once the needle reaches C, it indicates the water temperature has reached 60 degrees. The red H mark indicates 110 degrees. 2. It is ideal for the needle to remain in the middle position. If the needle enters the red zone, the water temperature is too high. 3. Prolonged high water temperature can lead to 'boiling over,' where the engine coolant boils, potentially causing the radiator to burst and the engine to overheat and sustain damage. Emergency tip: If the water temperature warning light comes on while driving at high speed, pull over safely as soon as possible. Do not turn off the engine immediately; instead, let it idle for two to three minutes with the engine hood open before calling for assistance. When the water temperature warning is triggered, the engine is running at high speed, and a significant amount of heat has not yet dissipated. Therefore, allowing the engine to idle helps lower the water temperature slightly, minimizing potential damage caused by overheating.
