Question What temperature is too hot???

My 2003 Grand Am normally runs at about 170-180 degrees but recently has been running at about 190-210 degrees. I just had the radiator flushed and the hoses checked and the fans are working. Is this considered normal and at what temperature should I get concerned? What would be the next logical thing to look at? Thanks for the help.

The temperature should only change if you have changed something. If you had a 180 degree thermostat installed the temp should be one temp, if you had a 195/210 degree installed it would read something different. However, if nothing has been changed start checking fluid levels, are the fans running and is the waterpump working. On modern pressure systems I think about 240 is where the red line starts. Have a good one. Geo

Sounds normal to me.
Modern computer controlled engines normally run around 200-220 to be super efficient. If your temp gauge is running away and leaning to 230 and up that's hot and you have a problem and can cause head damage.

My thoughts, too; I'm thinking the thermostat was changed during the work and it's higher temp stat. Also keep in mind the instrument panel temp gauge is not always 100% reliable; you could have a bad temp sender.
