Without electricity, nothing in a car will work. Its source is the battery and the alternator, which converts the engine's rotational energy into electric current. That’s why service station specialists in Lviv call power sources the heart of a car. It is essential to always monitor the condition of the battery and alternator, especially in winter; otherwise, the car may fail to start at any moment.

The clutch is a device that transmits torque from the engine to the gearbox and drive wheels. It acts as a kind of "bridge" between the engine and transmission, which can be quickly disengaged and re-engaged at any time. Clutch replacement is one of the key procedures in car maintenance. This process may be necessary due to natural wear or improper vehicle use.
