Today, I would like to share with you a water tank change operation.
Due to the wrong estimation of the height of the steps, the bottom was supported when going down the steps.
Embarrassed to leak the water tank on tiptoe.
At first, I wanted to apply for insurance repair, but later I estimated that it would be more appropriate to repair at my own expense after estimating the premium for the price increase in the coming year.
Fortunately, pay out of your own pocket.
Here, I would like to remind the majority of Boyue cyclists that although the SUV is higher than the average car chassis.
But do not blindly self-confidence to the higher steps, in the end are painful lessons ah !

Make an appointment for maintenance on Wechat in advance, stop at the store directly, and avoid wasting time waiting in line.
Because the position of the water tank is at the back, there are more things to be removed.
After the front bar was removed, several more large pieces were removed before the water tank was finally exposed.
The whole process of replacement will not be discussed here.
Directly above the picture, simple and clear ha!

[working principle of water tank]
The water tank is the heat dissipation system of cars, and most cars basically use water-cooled engines.
The water-cooled engine relies on antifreeze to circulate heat continuously inside the engine.
Antifreeze has two circulation paths in the engine, one is a large cycle and the other is a small cycle.
When the engine is just started, the antifreeze carries on a small cycle, and at this time, the antifreeze not only dissipates heat through the cooling water tank, which is conducive to the rapid heating of the engine.
When the engine reaches the normal working temperature, the antifreeze will dissipate heat through the cooling water tank, which can keep the engine in the normal operating temperature range.
The water tank is located in the front of the car, and there is an electronic fan behind the water tank.
When the vehicle is driving, the air flow will pass through the water tank, which will take away the heat of the antifreeze and lower the temperature of the antifreeze.
If the vehicle is still at rest, there are electronic fans to help dissipate heat.
When the electronic fan is turned on, it draws air inward, which can speed up the temperature of the air flow through the water tank, and can also take away the heat to help the antifreeze dissipate heat.
If the water tank is leaking, it is not very recommended to repair it outside. It is very likely that there will be a problem of leakage in the course of using the car in the future. The cost of repairing again is enough to replace a new water tank, so it is better to directly replace it with a new one.

[daily maintenance]

The water in the tank is not tap water or pure water as we usually call it, but coolant.
Automobile freezer is actually antifreeze, which is a chemical synthesis preparation, as long as the purpose is to prevent the engine cooling system from freezing at low temperature, followed by heat dissipation.
Antifreeze is the cooling medium of internal combustion engine circulating cooling system, which is mainly composed of antifreeze, corrosion inhibitor, defoamer, colorant, mildew inhibitor, buffer and so on.
We must use car antifreeze after winter, and it must be the same brand of car antifreeze.
Because the brand of automobile antifreeze is different, the composition may also be different, mixed together, it is easy to cause other problems.
Check regularly to see if you need to add antifreeze to be prepared.
