97 Suburban 2500 radiator????

[longbeach]

Checked out The Radiator Barn but my window for time was too small I needed to get it done. Ended up getting it at Napa and it fit right in, no adapters needed. I just bought this Suburban a few weeks ago and apparently someone had choked the cooling system full of leak stop. The first to go was water pump, I think that failed because of all the crap in the system. Then once the system was flushed the radiator leak showed up. Hopefully this will be it. My only concern is there are still remnants of that leak stop (like flaky pieces) left in the system. Is there anything I can add to dissolve that stuff. What a pain it would have been nicer just buying it knowing there was a radiator leak, a lot less trouble.
