ok my orginal radiator ate ----.... it was super clean from the inside, just that the end tank cracked, bought a used one for 20$ but its hella calcified on the inside, I already flushed the system, and ran it with the radiator cleaner, but its still dirty as ----, i am now gonna try using that CLR crap they show on TV, supposedly it removes calcium and rust... lets hope it works and doesnt work toooo well and eat up my water pump.

any suggestions? either do it or dont... or anyone ever try this?

just do it to the rad and flush it real good after, dont get that clr in the block or waterpump.

not even a little bit?

I wouldn't get any in the block or water pump either. Just try it out on the radiator first. Who knows what that shyt will do...
