How to Change an Oil Pump on a Car

Any car owner is expected to know basic car maintenance such as oil changes or fixing tire flats. Sometimes, car owners prefer to maintain larger parts of their cars as well. Keeping a car maintained is oftentimes able to be performed by the car owner and may even save money in the long run.

Items needed:

• Car manufacturer's manual


• Wrenches and sockets


• New oil pump
