The best automotive analogy I can think of is an aged out tire. Even if it has tread left, the material is degraded throughout. You can put a tube inside and get some more miles from it, but at any time it could fail catastrophically.
The material of the coolant tank has been pressurized and heated for many thousands of cycles. The bonds that bind the plastic on a microscopic level are failing. I don't think there is any practical way to extend it's use. Any patching of a crack would be short lived as the crack extends or a new one develops outside the patch.
