Check to see if the water pump is working? it could have a few broken impellers and is not moving enough water. Your radiator may be clogged and will need to be flushed with a flushing chemical. The radiator fins could be clogged with debris and should be washed with a good cleaner. Are the fans coming on when the car reaches temp? about 195 to 220 degrees. Check the radiator cap, you may also have a clogged vent tube..
