Antifreeze is an indispensable car care product that can ensure that the car can be used normally in cold climates without freezing, and it can also play a cooling role when the car engine has been operating at high temperatures. It is not only used in winter, but also in all seasons. So antifreeze is very important for cars. Antifreeze is also a consumable item. When filling the car with antifreeze, the upper limit is exceeded. Is something wrong? What should I do?
There are two types of pressure relief devices for antifreeze, one is the overflow pipe of the auxiliary water tank, and the other is the one-way pressure relief valve on the screw cap of the auxiliary water tank or radiator. The auxiliary water tank itself is a spherical shape, which can bear more pressure and can hold more antifreeze after expansion.
When the engine is running and the antifreeze is circulating, the auxiliary water tank is not full, which means that it can still bear it, and there will be no overflow or pressure relief. Only when the antifreeze liquid is added too much, the auxiliary water tank becomes full after being heated and expanded, and it will overflow from the overflow port or the pressure relief valve at this time. so,AntifreezeIt’s okay if the liquid is slightly over the upper limit, It just leaves some stains, no other effect, but it is better to use a syringe to pump out the antifreeze that exceeds the upper limit.
