For the Chevrolet Cruze, the temperature gauge needle pointing between 70°C and 90°C is normal. The temperature gauge is scaled in Celsius. When starting the engine, the temperature gauge should indicate no less than 50°C. During normal driving, the normal reading of the temperature gauge should be between 70°C and 90°C. If the temperature is low, drive slowly to warm up the car. A reading above 90°C indicates a cooling system malfunction, and the car should be stopped for inspection. The Chevrolet Cruze is a compact benchmark model developed by General Motors: 1. Body dimensions: length, width, and height are 4666mm, 1807mm, and 1460mm respectively, with a wheelbase of 2700mm; 2. Powertrain: equipped with 1.5L and 1.4T engines, with maximum power outputs of 114 horsepower and 150 horsepower respectively.

My Chevrolet Cruze has been running for eight years, and the temperature gauge needle steadily stays near the middle mark on the dial under normal conditions. After a cold start, it takes about ten minutes for the needle to gradually rise from the far left to the middle 90°C position, where it then remains steady. If the needle still fluctuates at a low position after half an hour of driving, it could indicate that the thermostat is stuck open, causing the coolant to circulate too quickly and preventing the engine from warming up properly. It’s even more dangerous if the needle enters the red zone—once, during heavy traffic, the engine temperature suddenly spiked, and I found out the radiator fan fuse had blown. Remember, if the needle exceeds two small marks past the midline, you should stop and inspect immediately, as coolant leaks or water pump failures can lead directly to engine seizure.

Last time I drove my Cruze on the highway, I specifically observed the coolant temperature gauge. The needle staying in the middle 90-degree zone is the safest. When just started, the needle is in the C zone (cold zone), and it rises to the middle and stabilizes after driving for three to five minutes. Don't underestimate this temperature - 90 degrees ensures optimal engine oil lubrication and also saves fuel. If you see the needle moving towards the H zone (high temperature zone), immediately turn off the AC, turn on the heater, pull over and shut off the engine. A friend of mine ignored a broken radiator fan, resulting in the needle reaching the red zone and breaking down halfway, costing over 5,000 yuan in repairs. I recommend checking the coolant level under the hood every month and replacing it immediately if it's dirty. The temperature gauge is the first to alert you if there's a cooling system issue.

The instructor taught me that the most accurate reading on the Cruze's temperature gauge is at the midpoint. In the morning when starting the car, the needle points at C; avoid stomping on the accelerator when the water temperature is around 50-60°C. Wait until the needle reaches the center horizontal line, which indicates the normal operating temperature of 90°C. If the needle is higher than usual, it might mean the coolant level is low—take it to a repair shop for a pressure test to locate any leaks. Once, my car's temperature was fluctuating like it was dancing, and the mechanic said the thermostat had failed, stuck in a partially closed position, causing the temperature to swing up and down. Another tip: in summer when the AC is on, the temperature might run half a notch higher than usual, but as long as it doesn’t hit the red line, it’s fine. This gauge is essentially a thermometer—if the needle stays steady in the middle, it means the engine is running comfortably.
