For the car oil pump damage fault, what method can be solved?
1. When the oil pump of the car fails, the car will be difficult to start, and it needs to start several times in succession to start the car. There will also be abnormal noise, humming while driving, and abnormal shaking of the engine trouble light. In these cases, it is likely that the oil pump of the automobile is broken, and it is necessary to go to the 4s shop or repair shop for professional inspection and repair as soon as possible.
2. The use of inferior gasoline, gasoline is full of a large number of foreign bodies and impurities, resulting in the oil pump suction screen blockage, some small impurities can not be filtered clean into the gasoline pump, easy to lead to abnormal wear of the oil pump. The gasoline filter is not replaced for a long time. If the gasoline filter is not replaced for a long time, it is easy to block the oil supply system, making it difficult for the gasoline pump to work. Long time high load, easy to cause oil pump damage in advance. The fuel pressure gauge can be used to measure the working pressure of the fuel pump. If it is lower than the normal working pressure, the low pressure oil pump pressure can be determined to be insufficient. When the automobile engine is working, if the pressure of the low pressure oil pump is insufficient and the gasoline of the high pressure oil pump is insufficient, it will lead to the failure of the high pressure oil pump.
3. Remember to replace the gasoline filter element after changing the oil pump. Dirty gasoline filter element will lead to heavy work load of oil pump and accelerate damage of oil pump. The fuel tank should be replenished in time, otherwise it will also cause damage to the car oil pump. The quality of the gasoline added is good, and the poor quality of the oil will also cause wear and tear on the car oil pump. If the pump diaphragm breaks, gasoline can leak through the diaphragm into the crankcase to dilute the oil, thus increasing the oil level. You can check by pulling out the dipstick. The above is the answer to the problem of oil pump damage to the car.
