What would make my 2004 Hyundai Sonata run hot when i stop at red lights drive throughtsect but cools back down when i start driving again

I had that problem with my 2004 Hyundai. My mechanic said it is from temperature guage in cluster was worn out after testing many ways to find faults. He did change the used cluster of my dashboard and it worked fine.. I spend lots of many of complaining of overheat. Have your mechanic check with electric temperature guage as it wont work right..

My 2003 just stopped running as i made a left turn everything works on it lights alarm ect it just wont start now it trys but wonk and one can help please and thank you
