The radiator is responsible for the cooling of the circulating water. Its water pipes and heat sinks are mostly made of aluminum. The aluminum water pipes are made into a flat shape, and the heat sink is corrugated. The wind resistance should be small and the cooling efficiency should be high.
Coolant flows inside the radiator core and air passes outside the radiator core. The hot coolant cools by dissipating heat to the air, and the cold air heats up by absorbing the heat dissipated by the coolant, so the radiator is a heat exchanger.
Generally, the radiator is located at the front of the car. When the vehicle is running, the air will enter here along the central air intake grille, so the dust, flying insects, leaves and other dirty things in the air will ride on the “air” Adsorbed on the air conditioner condenser and water tank radiator. If we do not clean these foreign objects in time, once they are blocked, the ventilation will be insufficient, which will affect the heat dissipation efficiency. In severe cases, the water temperature will be high, or even “boil the pot”.
For the cleaning of the radiator, if you have strong hands-on ability, you can consider cleaning it yourself; if there are many dirty things and the situation is serious, it is not recommended to clean it by yourself, or go to a regular car wash shop for cleaning! Because the radiator is also a very important part, there are many details in the cleaning process.
Before cleaning, the parts around the radiator must be sorted out to avoid hindering cleaning or damage during cleaning.
Step 1: Use an air gun to blow off foreign matter such as flying catkins and floating soil
If there are large debris such as branches and leaves on the surface of the radiator, you can clean it up by hand first, and then use an air gun to clean it up.
There is also a certain amount of attention when cleaning with an air gun. If conditions permit, try to use an air gun to clean from the cabin to the outside, so that the cleaned dust and debris can be blown directly outside the car instead of flying into the cabin.
In addition, it should be noted that due to its special structure, the radiator is not very dirty from the outside even if it is not cleaned for a long time. Therefore, many people will be deceived by its appearance. In fact, they are already full of dirty things inside. As long as we blow them with an air gun, these dirty things will show their true colors and run out.
Step 2: Rinse with water (it is not recommended to do it yourself)
In fact, in the previous step, the entire cleaning process is basically completed. Although water gun cleaning is mentioned in many radiator cleanings, it is not recommended to clean with a water gun if you do it yourself. One is because dry cleaning with an air gun can basically achieve the cleaning effect, and the other is because the pressure of the water gun itself is relatively high, and the heat sink is made of aluminum, so it is easy to bend it if you are not careful, and the final effect will be counterproductive. affect the cooling effect.
Therefore, it is best to go to a regular car wash room and let professional personnel clean it, because when cleaning, it is necessary to ensure that the water gun always enters the radiator vertically, and the angle must not be tilted, so as to prevent the angle of the radiator from being skewed.
