A car has many small parts such as the battery, radiator, brakes, axle, shock absorbers, etc.
Explanation:
These parts need repair from time to time. Our car does not work properly if any of such part is gone. This means if any part is damaged then the car will not move smoothly.
Suppose if the battery is dead then it will affect the voltage that the battery gives to the car. So we need to fix it. If the axle is broken, then driving can be hazardous. If the Radiator is leaking then the engine will overheat. This indicates the leakage of the radiator.
