The world of cars is a large sea full of information and secrets, and given its extreme importance, many motorists try to get acquainted with the principles of their maintenance, in order to act quickly in the event of any emergency breakdown while driving, and therefore we will learn the most important principles and basics of car maintenance, and car maintenance is divided Into groups as follows:

Lubrication group
This group is divided into engine oil, oil pump, filter, cartridge, and oil sump.

Engine oil: Experts in the automotive field advise to use the oil that the manufacturer recommends to the car, because of the advantages it contains that make the oil suitable with the car's engine, and it also helps increase the engine’s life span, and one of the main properties that must be met in good engine oil, she:

It is characterized by high degrees of viscosity, especially at high temperature, it is characterized by a high degree of evaporation, it has a low freezing point, and it must not interact with any part that comes into contact with it, and it is taken into account that it does not contain any carbon deposits.

The oil pan or cartridge is the oil tank, and the cartridge is installed at the bottom of the car's engine.
Oil pump or pump Usually oil passes from the sump to the filter until the impurities are trapped, then it passes into the pump in order to push it to the oil filter.

Oil filter Its mission is to seize the fine impurities that pass from the refinery to the oil passages, and it must be noted that with frequent use this part may become clogged, and therefore experts in the field of cars advise that the oil filter should be replaced every 10,000 km

Gasoline group
This kit consists of a gasoline tank, a pump, a filter, a carburetor, and a carburetor filter.
Fuel tank, where this tank is located at the end of the car so that it is away from the car's engine, to avoid any fire in the engine when any error occurs, it is made of steel, and the average capacity is 45 liters.

A gasoline pump or pump, which draws gasoline from the tank and pushes it towards the feeder again.
The feeder prepares the mixture of air and gasoline vapor in specific proportions, which pushes this mixture into the cargo complex of the car.
The carburetor or charge collector that part receives the mixture of air and gasoline and then distributes it to the cylinders of the engine.

The air filter The filter filters the air before entering the feeder, and it works to purify the air from
Any impurities or dust.

Cooling group
It is made up of radiators, hoses, a water pump, a fan, and the belt must be tight.
The coolant or the radiator, and this part consists of two basins for water, one upper and one lower, and between them are some vertical pipes and surrounded by a small group of blades, which have been added to increase the area exposed to the air in order to facilitate the transfer of high heat outside the car, as its function begins during the passage of hot water from The upper basin is down to the bottom so that this water is exposed to a stream of air, and a heat exchange takes place in which the air absorbs the heat of the hot water.

Water pump or piston, and this part draws cold water from the bottom of the cooler and pushes it back into the cylinder block.
The thermostat, or thermal valve, aims to control the water path in the car's cooling cycle according to the temperature.

Important notes about the refrigeration cycle
Caution must be taken when lifting the car coolant cover when checking the amount of water in it, because the temperature is high especially after the car's engine has been running for a long time, and therefore in that case you must move the cap without lifting it to get rid of the pressure inside the coolant and then lift the cap carefully.

Take into account at first the start of the engine, then after that the water is supplied, to prevent the supplied and somewhat cold water from descending to the bottom of the car cooler.

Take into account that the water used for cooling is clean and free of salts that may cause clogging of the pipes belonging to the cooling group.

The water in the cooling cycle must be replaced once every 6 months, as a maximum, with the addition of some solutions that prevent rust
