Why is there antifreeze fluid around the top edge of the radiator?

Good advice! Lol

We have a guy here that changes the gaskets and/or tank without replacing the radiator! :-)

Must be better than the guy i have had try to repair them. I find about as good of a deal from 1-800 Radiator. Then no worries later!

Have had several done, Rod, and Gasket R?R around $75.00. Some cost more with the tank, so R?R with new one is a better price.

I agree, depending on application.
