Probably when you drained the cooling system to do the water pump. Sometimes a little dirt is a good thing. It helps keep things sealed up. The radiator was probably going to start leaking anyhow but by changing the water pump and adding fresh clean coolant you just helped it along. Especially if this is the original radiator. I had to replace the original radiator in my '93 Chevy Caprice in 1999. Then again in 2005. Here's a depression-era trick my Dad taught me. Pour some black pepper in the radiator. The kind of pepper you put on your food. It doesn't dissolve and will seal up small pinhole radiator leaks. HTH. -Jim

Are you sure it is coming from the radiator? Can you see where?

Has it been overheated? If so, the radiator may now be bad from being overheated. Uhhhh, I wouldn't put anything in the cooling system other than coolant and water mix. It is much better to fix the problem rather than applying bandaids.
