Used Polo: Regularly replace antifreeze to keep the cooling system in good condition
WardHouston 
12 In the blink of an eye, it has been several years since the last time I replaced the antifreeze, and the number of kilometers has also increased. I think it is necessary to replace it regularly, so I plan to replace it in the near future. I have also operated it before replacing it, and it is not very difficult, so I still do it myself, the tools are relatively simple, and they are always available, and when I have time on weekends, I start work.
It’s an old car in good condition.
Drain water by removing water pipes.
Replace the car after it is fully warmed up.
Lay it well for easy bending and operation.
One basin and one tool are enough.
This tool is dedicated and specially matches the public clamp design to prevent falling off.
It can be seen that there are two main differences: one is the concave point matching the clamp, and the other is the self-locking device on one side.
Matching dimple design.
The lower pipe clamp was simply removed.
Open the lid of the auxiliary kettle.
The water fell sharply.
Old antifreeze flows into the basin.
Pinch down the upper water pipe back and forth to drain the antifreeze.
Of course, you have to apply pressure and use pressure to blow it out.
Match the air pump with the towel.
When you open it, you can see the whoosh and the antifreeze is discharged.
Once it is drained, put on the water pipe and tighten the clamps.
Operation is simple with special tools.
I have prepared 2 bottles of original antifreeze.
Dedicated.
Pink, start pouring.
Then heat up the car until the water temperature is normal.
Antifreeze will drop a lot.
Fill it up again.
Go out for a run and clear the air.
Until the fan turns and the large cycle turns on.
At this time, the upper and lower water pipes are hot, indicating that the thermostat is open.
The antifreeze drops again and is added to the normal scale.
Regular replacement is good for the car. There is no need to delay it and it is not very troublesome. It is recommended to replace it regularly. It is good for the car and will make it more safe to use it in ordinary times.
