oil and water temp gauge

• 2022-03-03

The water temperature gauge reflects the temperature of the engine body to indicate whether the engine works normally. The fuel gauge reflects how much fuel the car has to estimate how far it can travel. Generally, there are only water temperature gauge and water temperature alarm lamp on the vehicle. Generally, there is no oil temperature gauge and oil temperature alarm lamp on the vehicle. The sign of the water temperature alarm light is that there are two wave lines below, and a thermometer is inserted in the wave line.

Most cars use water-cooled engines, which rely on the continuous circulation of coolant for heat dissipation. There are two circulation paths of coolant in the engine, one is large circulation and the other is small circulation.When the engine is just started, the temperature of the engine is relatively low. At this time, the coolant is circulated in a small cycle, so that the coolant will not be dissipated through the cooling water tank, which is conducive to the rapid temperature rise of the engine.Sometimes, part of the oil temperature is dissipated by the water temperature, and the other part is the natural heat dissipation of the oil pan. Under the hot vehicle state, the oil temperature in winter is likely to be lower than the water temperature, and it is basically higher than the water temperature in summer. The water temperature and oil temperature designs of different models are inconsistent.

However, the water temperature alarm light on the instrument panel will light up, If the water temperature is too high. Some buses have a water temperature hand on the instrument panel. From the water temperature hand, the motorist can see how numerous degrees Celsius the water temperatureis.However, they need to install some measures and detectors, If riders want to know what the canvas temperature is. Generally, there's an canvas temperature hand only on some super sports buses or contending buses, and there's also an canvas pressure hand on contending buses or super sports buses. Some high- performance sports buses also have turbine pressure needles.

Ordinary driving oil temperature is lower than water temperature. The normal temperature of the automobile water temperature gauge is 90 degrees in the center, and the stroke of the water temperature gauge is 0 to 130 degrees. After the vehicle is started, the water temperature rises rapidly. After the pointer reaches the central position, the water temperature will no longer rise, and start when the temperature reaches the middle position. Cooling system faults mainly include liquid leakage, insufficient coolant, cooling fan fault and circulating water pump fault. The data on the water temperature gauge is only approximate, and the actual temperature is not the same as the instrument display. The actual water temperature can be read by the computer for car repair or the OBD driving computer reader for private cars. Due to different design ideas of engines from different manufacturers, the normal driving temperature is also different. Generally, do not exceed the red line on the table.
