take it to a radiator shop and have them rod the core and reseal the tanks ir just get a new oem.

or just start flowing water threw it with some sort of flush stuff. all i could think of.

you can find oem rads for like 100-120.

that's what I've been doing, flushing it with hot water, cold water and those radiator flushinf solutions at the auto store. I'm wondering if there's some special bottle that I have to use to do the trick. This is my mishimoto radiator and it's basically brand new so I want to try flushing before I get a new one.
