Never add water.
You must add the same type of antifreeze.
This is necessary when the antifreeze level does not reach the required height.
Automatic cars do not have a clutch, which is very uncomfortable for many people used to driving manual cars. They often put their left foot out of habit, causing sudden stops.
This is very dangerous when driving on the highway. Therefore, if the owner of a car with a manual transmission turns away from a car with an automatic transmission, he must first practice immobilizing his left foot and keeping his left foot on the ground. left side. Place your feet in the corner until you get used to it.
The automatic transmission, as the name suggests, does not require the driver to change gears manually. The vehicle will automatically select the appropriate gear based on the speed of the vehicle.driving and traffic conditions. There are six gear positions in general automatic transmission cars, from top to bottom: P, R, N, D, S, L.
What owners of cars don't know about antifreeze!
Antifreeze, it is estimated that many people will mistakenly think that it is a liquid that is added separately to the vehicle in winter! Would you be surprised if vehicles used antifreeze all year round? Actually, antifreeze is just a term, it's not just antifreeze. In fact, antifreeze and coolant both talk about the same thing: cooling the engine by circulation!
The role of antifreeze
Provides anti-corrosion protection to the components of the cooling system
The engine and its cooling system are made of metal, in particular in copper and iron, aluminum, steel and solder When these metals come into contact with water at high temperatures, they corrodent and rust over time. The most common antifreeze is alcohol, which reduces electrochemical corrosion between different engine parts compared to distilled water. Additionally, the antifreeze itself will add anti-rust agents, which will allow the antifreeze to minimize corrosion of the system.
Anti-corrosion protection of cooling system components
Antifreeze is mainly composed of alcohol, which can prevent precipitation of calcium and magnesium caused by the hardness of the water, thus avoiding the accumulation of components. at the ends and a blockage forms.
Ensure that the engine can operate within the normal temperature range
Therefore, the engine antifreeze should have the characteristics of antifreeze, anti-boiling, anti- corrosion, anti-freeze. -scaled, moss-free, and not affected by seasons and regions. Among them, freezing point and boiling point are the indicators ofbase of antifreeze.
The lower the freezing point, the better
The basic indicators of antifreeze are freezing point and boiling point. The freezing point of antifreeze should generally be more than 10°C lower than the local minimum temperature to prepare for sudden weather changes. The general freezing point range is between -25°C and -50°C, which can meet the antifreeze needs of vehicles in most areas of northern China.
The boiling point of antifreeze is generally 110-120°C and the boiling point of water is 100°C, which also prevents your car from "boiling" . The normal operating water temperature of general domestic vehicles is 87-105°C, and some vehicles are even higher.
