after reinstalling my battery on my truck the oil gauge and water temp gauge are jumping around

When I reinstall my battery on my truck , the oil gauge and water temp gauge are jumping around, what’s the reason? The water temperature sensor may be faulty. The main reason why the Fujida Yuling oil gauge and water temperature gauge jump is that the water temperature sensor is faulty. The water temperature gauge can visually display the working temperature of the engine water tank, so as to ensure that the engine operates within a suitable temperature range. Too high or too low will affect the engine performance. If the gasoline meter and water temperature meter share the same instrument regulator, it may be that the instrument regulator needs to be adjusted. The gas meter and water temperature meter are connected together. It is also possible that the instrument is broken, and other positions will not be broken at the same time. Replace the instrument. The water temperature is too high and the oil quantity is too low. The flashover of the water temperature meter and the oil meter in the truck is caused by the high water temperature and low oil volume. Try to cool the water temperature to the local gas station for refueling.

The cause that cannot be underestimated is "truckbon deposition", which will cause insufficient combustion of gasoline and cause engine jitter. The impact of engine truckbon deposition on the truck is quite large. First of all, it is to reduce the engine power, which means that the power output is uneven and gradually attenuated, in other words, it is becoming less and less powerful. Second, increase fuel consumption and increase your economic burden. Third, it is difficult to start cold, that is, it is difficult to ignite, and it is not easy to start the truck. Finally, the truckbon deposit in the combustion chamber is severe, which will also cause cylinder knock, low speed acceleration noise, damage to the piston and crankshaft, cause engine high temperature, and seriously affect vehicle safety. Another is that the emission exceeds the standard, which not only fails the annual examination, but also directly aggravates the harm of polluting the environment.Another reason is that the throttle valve is faulty. The above two problems will cause engine jitter and unstable speed. When the water temperature gauge jumps randomly, it is generally not a fault.
