Replacing the hot air tank will lead to the failure of antifreeze.

1. Sealing problem of cooling system. The joint of cooling system connecting antifreeze tank and water tank is not tightly sealed, which leads to antifreeze leakage.

2, pipeline problems, pipeline aging cracking, antifreeze leakage.

3, water tank problem, water tank corrosion, antifreeze leakage.

4. The location of water leakage is mainly around the water tank, so you can check whether there is liquid on the surface of the water tank and the joint of the pipeline.
