1: The heat sink should not come into contact with any acid, alkali or other corrosive properties.

2: It is recommended to use soft and hard water after softening treatment to avoid the internal blockage and scale generation of the radiator.

3: In the use of antifreeze, in order to avoid the corrosion of the radiator, please be sure to use long-term anti-rust antifreeze produced by regular manufacturers and in line with national standards.

4: During the installation of the heat sink, please do not damage the heat sink (slice) and the bumper heat sink to ensure heat dissipation and sealing.

5: When the radiator is completely drained and refilled, first turn off the water discharge switch of the engine block. When there is water flowing out, close it again to avoid blisters.

6: In daily use, the water level should be checked at any time, and water should be added after cooling down. When adding water, slowly open the water tank cover, and the operator's body should be as far away as possible from the water supply port to prevent the high pressure steam oil from being sprayed out to cause burns.

Car radiator cleaning steps

The first step: remove the grille

Cleaning the radiator is not a difficult task and it is very convenient to operate. We can ask the staff to assist in cleaning and even cleaning by ourselves when repairing the car and washing the car. Of course, the first step is to remove the front grille. Since the heat sink is placed inside the front grille, it is the first step to remove the front grille. Due to the difference in design of each model, individual models can only expose a small number of radiators even after the grille is removed, so cleaning will be relatively time consuming.

The second step: air pump cleaning

If there are large debris such as branches and leaves on the surface of the radiator, you can clean it first by hand. If not, you can clean it directly with the air pump. (There are many small air pumps on the market, or you can use the air pump in the car wash shop. ). Air pump cleaning has certain requirements. If possible, clean the air from the cabin with air pump. This method can make the dust and debris cleaned out directly outside the vehicle without flying into the cabin. Of course, the internal structure of each car will be different. Some cars can't push the air pump in from inside, and it can only be cleaned from the outside. Many times, even if it is not cleaned for a long time, the radiator is not very dirty from the outside. Therefore, many friends will be deceived by its appearance. In fact, a lot of dirt has already accumulated inside the radiator, and it will spread out when blown with a gas pump. Blow repeatedly several times until no dust is released and the basic cleaning is complete.

The third step: washing (not recommended)

In fact, in the previous step, the entire cleaning process was basically completed. Although many of the cleaning of the radiator mentioned the water gun cleaning, it is generally not recommended to use a water gun for cleaning. The reason is that the cleaning effect can be achieved by the air pump. Secondly, because the pressure of the water gun itself is relatively large, it is easy to slam the heat sink with a little care, which will affect the heat dissipation effect. Of course, some car owners who are pursuing perfection will feel that washing without water is not thorough. If this is the case, then you must go to the regular car wash room for cleaning, and the water gun should be straight into the radiator when cleaning, the angle should not be tilted to avoid the angle of the heat sink.

How to prevent car radiators from "opening"

In the hot summer days, the sun is burning and the temperature is rising. In such a high temperature state, the water temperature of the car is likely to rise sharply, causing "opening the pot", and the owners of the car owners should prepare for the car to cool down in advance. However, how to prevent the car from "opening the pot"?

Check the cooling system

The owners of the car should always check the cooling system, do their maintenance work, and ensure the sensitivity of the radiator, fan and other components.

Cleaning the tank surface

If the surface of the water tank accumulates excessive dust and other impurities, it will seriously affect the heat dissipation performance of the water tank. Therefore, the dirt on the surface of the water tank should be cleaned up in time.

Water tank should be filled with water

The owner should check if the water tank is short of water and fill it up in time before leaving the car every day. In addition, you can store a bucket of water in the trunk for emergency use.

Pay attention to the water temperature while driving

If the owner of the car wants to travel long distances or travel for a long time, he should pay attention to the water temperature during the driving process. If the water temperature is too high, stop the car to a safe place to rest.

Traffic jam

The owners of the car owners can turn off the air conditioner when the traffic jams, thus reducing the speed of the water temperature rise and preventing the car from "opening the pot".

Use hot air to cool down

If the car has a “opening” phenomenon, the owner can adjust the air conditioning in the car to the external circulation and hot air. This can help the engine to cool down quickly.

Warm reminder: You should regularly check the heat dissipation system, clean the surface of the water tank, and fill the water tank with water; pay attention to the water temperature when driving, turn off the air conditioner when the traffic jams, to prevent the car from "opening the pot"; if "opening" has appeared, Use hot air to cool down.
