I replaced my radiator a little over year ago with a bigger one I got from LMC. The thing has never overheated once and I was very happy with it until now. It is leaking (slow drip) from somewhere right by the lower hose on the passenger side. Looks like it might be the seam where the rows/fins meet the side part of the radiator. I have looked and it is not the pet cock (gigidy gigidy) and it is not the hose either. Does LMC warrenty their stuff? Also if not, what kind of that radiator stop leak stuff works the best?
