new 195 Tstat in yet and still hitting 230?
any airflow obstructions?
Did you properly flush it yet?
did you check the overflow hose?
flush out the overflow bottle?
have you replaced the rad cap yet?
ALL of these things should be done before asking questions. Too many variables until you start eliminating some.

New water pump. Fans work I'm pretty sure. Radiator doesn't look like its clogged And I have coolant in the system. It really only gets too hot when its at idle or in town. I'm just trying to see what anyone else thinks it could be.
