Assuming the core is the problem and it is not the zigzag type not amenable to cleaning, tank removal is not a big deal. Professionals do very quickly. I have done it on other makesĀ using a plumbers petrol iron but easiest with a small hot flame directly. The radiator is supported so the solder falls clear and not into tubes and the joint is repeatedly tapped as the solder is melted. This prevents it re adhering.
