oil pressure and coolant temp gauge that works
The normal coolant temperature of different engines is different, as follows:
1. The normal water temperature of Ma 6 coolant thermometer is in the fourth grid, which is 90 °.
2. The coolant thermometer of mingjue Ruiteng engine is normal within 105 ℃.In cars, the coolant is added to the water tank, so the water temperature gauge, also known as the coolant gauge in the profession, is actually the same gauge.In order to ensure that the engine works within the normal temperature range, the vehicle will be equipped with an engine coolant temperature sensor, which is usually displayed separately on the vehicle dashboard (water temperature gauge). If the antifreeze temperature is too high, an alarm will appear. Generally speaking, the engine water temperature gauge adopts physical or virtual dial pointer display, while a few vehicles have no instrument panel, and only warning signs appear when the temperature is too high.
Whether it is a physical or virtual water temperature gauge, its pointer orientation is basically similar, which is generally marked with 60 ℃ --120 ℃ dial or cold (c) -hot (H). Antifreeze is different from traditional tap water. Its added calcium chloride, methanol, ethanol, glycol, glycerol and other components in organic matter enable it to work at a temperature above 100 ℃.
From the above introduction, we know that the engine coolant temperature is not the lower the better, nor the higher the better. It needs to be within a certain range. The normal temperature is 90 ℃ in the center of the pointer. After the vehicle is started, the antifreeze temperature rises rapidly. After the pointer reaches the central position, the antifreeze temperature of heat exchange balance will no longer rise.It is best to start when the temperature reaches the middle position, which is one of the reasons why the vehicle should be hot before starting.The pressure produced by the engine oil is different under different temperatures, that is to say, the engine oil has a certain viscosity, because it is produced annually, so the year will change due to the change of temperature, and finally the pressure produced by the engine oil will change slightly. Under the normal operating temperature of the engine, only the pressure is the most normal, so under the operating temperature of the engine, Pressure on the side is the most standard
