well i just re flushed the system nothing leaked and the water was moving freely with no problem, no gunk or anything so i think i am going to leave the system filled up with water only and see what happens to the temp. Is there any way that the radiator could be the problem? some of the fins are pretty messed up maybe air isn't flowing threw it right? fyi the fins were smashed when i bought it. just never thought it would cause a problem
