Leakage of antifreeze in 7th generation Honda Accord?

The joint between antifreeze tank and water tank is not tightly sealed, or the rubber tube is aged and cracked.

Check whether there is leakage in the coolant pipeline, especially at the joint of the upper and lower water pipes of the radiator, the water outlet on the cylinder cover and the pipeline interface of the water pipe, warm water tank and water temperature sensor. Generally, it can be solved by applying sealant to joints, reinstalling water pipes and replacing clamps.
