Think it may be a bad water pump,

new water pump replaced 6 months ago.

If you have replaced all this,you may need to have it pressure checked,if it turns out good,one of the new part,s pertaining to the coolant system is bad,could be new bad thermostat or water pump IMO.

Thanks ill take car to a shop for a pressure check .

When the radiator was replaced was all the dead bug goop, dirt and leaves cleaned from the backside of the a/c condenser?

new radiator was replaced about 12 months ago with new hoses , there s never been overheating since . the over heating just started on my car about 10 days ago with the hot weather . the only thing I've done right about before the problem started was opening the radiator cap to check water level which I do every about 30 days cause it has 275,000 miles

finally found the cause of the overheating , it was the engine coolant temperature sensor. Last year in November I replaced the "ect" sensor because there was a trouble code that appeared . This time there was no trouble code or anything appearing. And the ect is also part of the temperature measurement. So I replaced the ect since I had warranty , taking a chance on it before doing anything more expensive. now the car runs normal.

Good deal, I'm glad it was something fairly simple and not too costly. Thanks for letting us know.
