how hot should the car be running?
If the entire cooling system is working it shouldn't get that hot.
I think "normal" temp is different for everyone. Mine runs around 185* all the time as long as I'm moving. If I stop or sit in traffic it creaps up a little bit.
One of the culprits that noone ever checks is a clogged A/C condensor. Over the years little rocks, sticks, pebbles, grass, etc. will clog it all up.
