I beg to differ. I got great loads (easily over 2 cups) of sediment out of the radiator in my Chevy truck earlier this summer. Now, it wasn't completely clogged and I ran probably 100 gallons through it--with the radiator out, and shifting the angle around so the water could reach all the various internal passages. A radiator is just plumbing, whether you can remove a clog depends on where it's clogged and what it's clogged with. It's worth a try, especially if you're on a budget. If you can get it to flush clean, you don't have to buy a radiator. If you can't, what have you lost? An hour and a half of time, dry shoes, and maybe a dollar's worth of water. If I tried that and couldn't get a blockage out, I might try filling the radiator with water and CLR and letting it soak for a couple of days to dissolve calcium, lime, and rust deposits. Yes, it might screw up the radiator--but the radiator's already screwed up, right?
