Based on the mileage of a car, to keep it in perfect working order it is necessary to carry out a series of maintenance operations.
This is called scheduled maintenance.
Some parts of the machine in fact tend to wear gradually and must be replaced in good time before they fail, among these we can remember the engine oil, tires, belts and other parts of the engine.
Over time, others need to be replaced such as the battery and the seals which tend to stiffen and allow water to leak.
The battery is relatively easy to replace, just go to a car accessory and buy a battery of the same amperage.
To disassemble the old one and replace it with the new one, you only need a few keys and a little forethought.
