Everyone is no stranger to automobile coolant. Coolant is also called antifreeze. As the name suggests, it can cool the engine and has an anti-freezing effect. It plays a crucial role for the engine. The coolant circulates in the engine and cooling system and quickly cools and circulates under the action of the cooling system, taking away the excess heat generated by the engine during work, keeping the engine always running at a normal temperature. It also has the effect of preventing corrosion and removing rust. Effectively protect the engine cooling system. In winter, the anti-freezing effect is particularly important. The temperature in winter is low. If the coolant freezes, it will not only fail to cool the engine, but also may freeze the cooling system and even freeze the engine cylinders and cylinder heads. Therefore, it is said that coolant is an indispensable part of the engine. So is the coolant time-sensitive? The answer is there. Normally, it should be completely replaced every two years or 30,000 kilometers. The long-term model can be used for three years or 50,000 kilometers. My Xiaolang is just three years old this year. In addition, it is located in the Northeast and has the lowest temperature in winter. It can reach about minus 30 degrees. I am really worried about the freezing point of the coolant, so I decided to replace it and chose to replace it at a local 4s shop. I feel that the accessories on the 4s side are more reliable and feel safe to use it.
Arriving at the store, the service consultant picked up the car
After explaining the purpose, the service consultant fills out the form and registers
Because you came early, you didn’t have to queue up and drive the car directly to the workstation and lift the car up.
Remove the bottom guard and prepare to pour out the antifreeze
Soon the bottom guard was removed,
The thick water pipe at the bottom of the cooling water tank needs to be removed
The master moved quickly, the water pipe was quickly removed, and the antifreeze flowed directly out
Soon, the coolant was almost done. The maintenance boy put the vehicle down. It turned out that the coolant had not flowed completely. The little boy had to pump up in the kettle and completely discharge the remaining coolant through the airflow.
Sure enough, there was still a lot of residual coolant flowing out
In the end, a total of half of the basin of antifreeze was poured out, and the color still looked good
Next, the young man will lift the vehicle again and fix the water pipes.
Install the bottom guard
Carefully replenish Xiaolang’s tire pressure
Looks like all four wheels are a little short of air.
After replenishing the air, put Xiao Lang down and prepare to add new coolant
The little brother said he needed three 2L barrels of antifreeze added this time
After reading the instructions, the freezing point of this antifreeze is minus 50 degrees. Okay, I came for this, so I can use it with peace of mind.
Start adding the first bucket
The second bucket, after adding the second bucket, I saw that the liquid level was already at the standard position. Later, the little brother said that there may still be air and the liquid level will go down in a while. Okay, you have experience, listen to you
Continue to add the third bucket until it exceeds the standard line by about two fingers, and there is still more than half of the bucket in the bucket. After taking this back, you can add it yourself if the coolant is missing.
At this time, the repair and maintenance ended. It took about 40 minutes. It was time to check with the billing clerk. The cost this time: Coolant:73 yuan, 3 barrels =219 yuan
Working hour fee:98 yuan, 30% off =68.6 yuan
A total of 287.6 yuan.
