3 & 1/4 gauge car water and oil temp autometer

For 3 & 1/4 autometer gauge car water and oil temp,The oil temperature is the oil temperature and the water temperature is the coolant temperature. Generally, there is only one of the two on the instrument of a car. The engine temperature is first transmitted to the oil and then to the coolant, so these two indicators mean the same thing.Ordinary cars only have water temperature gauge and water temperature warning light, while ordinary cars do not have oil temperature gauge and water temperature warning light. The sign of the water temperature warning 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 to dissipate heat. There are two circulation paths of coolant in the engine, one is large circulation and the other is small circulation.

When the engine reaches normal operating temperature, the coolant circulates heavily. At this time, the coolant will dissipate heat through the radiator tank to keep the engine temperature within the normal range. If the water temperature is too high, the water temperature warning lamp on the instrument panel will illuminate. Some cars have a water temperature gauge on the dashboard. From the thermometer, the driver can see how many degrees Celsius the water temperature is. If riders want to know what the oil temperature is, they need to install some meters and sensors. Generally, only some super sports cars or racing cars have oil temperature gauges, and racing cars or super sports cars also have oil pressure gauges.

How to check the car thermometer: 1. The water temperature is from C to H; 2. When the pointer points to C, the temperature is 60 degrees; 3. When the pointer points to the H red grid, the temperature is 110 degrees. The sensor of the water temperature gauge is a thermistor type sensor, which is fixed on the engine cooling water channel with a thread. The thermistor determines the amount of current flowing through the coil winding of the water temperature meter, which drives the pointer of the meter head to swing. In the past, the cooling water of automobile engines was used as tap water, and now many automobile engine cooling systems use special coolants, so they are also called coolant temperature gauges.
