different ways to check fuel level with broken gauge
1.The easiest way to check the gasoline is to start the engine. Just look at the gasoline meter on the dashboard and refuel when the pointer is behind the car. Generally speaking, even if the fuel needle falls to the bottom line, there is still about 3-5 liters of gasoline in the fuel tank. Failure to refuel may cause flameout without oil. If we smell a strong smell of gasoline while driving, we can't be sure what happened. We can get out and check the exhaust pipe and engine. If we find a pool of gasoline in the groove of the engine, we need to deal with it in time, otherwise it will have unimaginable consequences or even spontaneous combustion.
2.The reason for gasoline leakage is also very simple, mainly because some parts of the engine compartment are metal and some parts are rubber. In winter, the rubber part will become hard, and the vibration of the engine will cause leakage after the interface between the metal oil pipe and the rubber oil pipe, which will also lead to the routing of the engine. Under normal circumstances, after we heat the car, the smell of gasoline will disappear, which means that there is no abnormality in the engine and other places. But now all vehicles will be equipped with three-way catalytic converters, whose main function is to fully burn the gasoline that is not completely burned, which can effectively prevent you from smelling the smell of gasoline.
3.Before testing the system oil pressure, first release the pressure, and then connect the oil pressure gauge to the oil circuit. Some system pipes have oil pressure inspection holes, while others do not. If there is an oil pressure inspection hole, the oil pressure gauge can be directly connected to the oil pressure inspection hole; If there is no oil pressure inspection hole, remove the oil inlet pipe, connect the tee pipe connector in series with the oil inlet pipe, and then connect the oil pressure gauge to the tee. After the engine is shut down, pull up the dipstick to wipe it clean, then insert it back, and then pull up the dipstick to check whether the oil level is between the standard upper limit (MAX) and lower limit (MIN). If your car is old and you eat oil on weekdays, you'd better take a can of spare oil of the same specification in the trunk for a rainy day.
