Cleaning Radiator

I would like to know if anyone has been able to clean the junk out of there 02 Impala's radiator after they flushed out the dex-cool? I thought I had it done but the car is still getting hot.

thats good you flushed it out. you might have a small hole somewhere. after I flushed mine out it still overheated. come to find out it was a gasket leak
