A car cooling system.Most car engines are cooled by water. The water flows around the engine and then passes through the radiator. It then passes through the water pump and around the engine again.

Thus, there are several stages in this cycle:

1. Water flows around the engine. The engine is cooled and water is heated.

2. When heated, the hot water enters the radiator through the top hose (шланг).

3. Flowing down through the radiator, the hot water is cooled by air. The air is drawn through the radiator by a fan (вентилятор). This fan is turned by a belt, which is driven by the engine. The cool water leaves the radiator through the bottom hose. The water is pumped around the engine again.

Finding a fault in a car.If your car doesn't start in the morning, you should check three things first: the battery, the fuel level and the spark plugs (свеча зажигания). It is easy to repair these faults. If the battery is flat, you should recharge it. If this doesn't work, you should replace it. If the petrol tank is empty, fill it up. If the spark plugs are dirty, clean them, and if the gap in a spark plug is too narrow or too wide, adjust it to the correct width.

If your car still doesn't start, the petrol pump may be broken, or the fuel pipe may be blocked. If the pump is broken, it must be repaired or replaced. If the fuel pipe is blocked, take it off and unblock it.

If there is a loud click when you turn the key, the starter motor may be jammed (заклинивать). If it is, you can try to release it by pushing the car forwards and backwards (in 2nd gear). If the car still doesn't start, the starter motor should be repaired or replaced.
