changed water pump now temp gauge doesn't work

If changed water pump now temp gauge doesn't work , first, check whether the wire ends are broken and loose. If ok, the water temperature sensor instrument is broken. You can unplug the water temperature sensor and put the plug on the wire. Open the key and look at the thermometer on the instrument every time you turn. If the water temperature sensor is broken, do not replace the instrument. The power line of the water temperature gauge is disconnected, the electric heating coil of the water temperature gauge is burnt out, and the electric heating coil of the water temperature gauge sensor is burnt out or has poor contact. The wire of the water temperature gauge sensor is improperly connected or disconnected. The voltage regulator that provides a stable power supply for the water temperature gauge circuit is damaged. Try it. The heater is hot. And the temperature of the upper tube and the lower tube is the same. It is recommended to check whether there is a thermostat. After confirming that there is no problem, consider the sensor, circuit and water temperature gauge. It should be that the thermostat is broken, the thermostat is always open, and the coolant is always in a large circulation state. Summer is better, but it is difficult to get water temperature in winter.

When the vehicle is just started, the water temperature is generally very low, especially in winter. At this time, it is necessary to warm up the vehicle first. The hot car after starting the car ultimately depends on whether the water temperature is normal. Generally, the warm-up is completed when the water temperature gauge reaches the middle position. At this time, you can drive according to your driving habits. Before that, drive slowly. Do not turn on the air conditioner if the water temperature does not reach the normal temperature. Otherwise, it will damage the engine and increase fuel consumption.

The water temperature is very important when driving, but strictly speaking, what our water temperature gauge shows now is not the so-called water temperature. You can think about it. If we operate according to the regulations, we won't have a chance to add water to the car.

The water inlet of wiper should be filled with wiper agent, and the antifreeze inlet should be filled with antifreeze, so the water temperature on our car now shows the temperature of antifreeze. The water temperature actually refers to the temperature of antifreeze. In addition to the oil pipes, the engine is also covered with antifreeze water channels.
