1999 Oldsmobile Cutlass

I have a 1997 oldsmobile and I was leaking antifreeze for month's. I was going thro a container of antifreeze every few day's. I went to K-mart and found this stuff for like 4-6 dollar's. It has some pellet things in it, all you have to do is pour it into the radiator and top it off with the antifreeze, it runs through the system and stops any leaks you may have. I forget the name of it but it is right in the car crap isle. Good luck and I hope this helped
