How to Read the Chevrolet Temperature Gauge?
2 Answers
Water temperature ranges from C to H, where C represents 60 degrees. When the gauge pointer reaches C, it indicates the water temperature has reached 60 degrees; the H red mark represents 110 degrees. It is ideal for the pointer to remain in the middle position. If the pointer enters the red zone, the water temperature is too high. Prolonged high temperatures can lead to "boiling over." When checking the electromagnetic temperature sensor and the temperature indicator gauge, you can disconnect the sensor's wiring and measure the resistance between the sensor's input terminal and ground. If the thermistor's resistance is approximately 100Ω at room temperature, it indicates the sensor is in good condition.
I've been driving my Chevrolet for several years, and checking the temperature gauge is a routine task. The temperature gauge is usually located on the dashboard, displaying a small thermometer icon or a scale marked with C and H, where C stands for cold and H for hot. Under normal conditions, the needle should be in the middle position, around 90°C. If the needle leans towards the left near C, it indicates the engine is too cold, and you might need to wait a bit before accelerating after starting. If it moves towards the right near H, you should be cautious as it might indicate overheating—promptly pull over to check the coolant or fan. I make it a habit to glance at it before driving to ensure the temperature is normal. Occasionally, if the needle fluctuates up and down, it could signal a cooling system issue, like a faulty water pump or a radiator problem, and it's best to get it fixed at a shop immediately to prevent serious engine damage. Developing a habit of regularly checking the coolant can also help prevent potential issues.
