JourneymanDepending on the size of the leak stop leak can work but it's only a temporary fix and the radiator should be replaced. Bars leak makes a stop leak in a liquid form that works well.

ReplyEnthusiastIf it's leaking bad you need to either replace it or repair it, depending on the radiator design. Stop leak and or any type of additives that are designed to reduce small leaks might reduce the actual leak problem, but will eventually cause other problems that can cost more to repair. I would say be very careful when using any additives in engine and trans since most of them have side effects that can be costly.
