I need to change the coolant in my vehicle to which radiator stop leakage was added. Will the radiator stop leakage action be maintained or do I need to add another one to prevent the leakage from reappearing?

The Radiator Stop Leak is composed of plant particles that come to position themselves in front of the holes to plug them. They will drain off with the coolant when draining. It is therefore necessary to replace the Radiator Leak Stop with the new coolant to prevent the leak from reappearing.
