Hello, everyone, the thermometer of my car is slowly rising. Is it normal?

Nothing, as long as the water temperature is not high. There is a warm-up process after the vehicle is started. The phenomenon that the water temperature rises slowly is that the engine is warming up. The length of this time depends on the water temperature detected by the water temperature sensor. If there is nothing wrong with the water temperature sensor, it may be that the thermostat keeps circulating for a long time, causing the water temperature to rise slowly.

When the thermostat can't be closed normally, the automobile cooling system has been in a state of large cycle since the cold start. The water temperature will rise slowly, especially in winter, and the hot car will be particularly slow. When the water temperature is low, the signal provided by the water temperature sensor to ECU will increase the fuel injection quantity of the engine.

Or some improper operation will also lead to slow water temperature rise or poor heating effect.

Consequences of too low or too high water temperature in the car

1, the high temperature in summer makes it difficult for the water tank to dissipate heat, and the water temperature of the engine will rise in different degrees, and the hose will be softened more easily, and the cooling water will leak. Therefore, it is common that the water temperature is too high or even boiling during driving.

Normal engine water temperature should be constant between 85-95 degrees Celsius. When the water temperature is too low, the fuel can not be atomized well when entering the cylinder, and the power and economy are not good. Moreover, the gap between parts is too large at low temperature, and the noise and vibration will be greater.

2. If the water temperature is too high, the viscosity of the engine oil will become thinner and the lubricating strength will decrease. At the same time, the piston, valve and other high-speed moving parts are more prone to deformation, resulting in engine weakness. In severe cases, the expanding and deformed piston will strain the cylinder, and the crankshaft bearing will dissolve and lock the crankshaft, with disastrous consequences. Therefore, if the pointer of the water thermometer is close to the red area, or the water temperature warning light is on, you should immediately pull over and check the flameout.
