 HI - I would check all hoses and check that the fan is working right. also if it is that hot I would remove the thermastat for the summer time.I would first do a pressure test on the cooling system to check for any leaks. also how is the rad. cap.

  Hi  if you changed all of that , and it is still running hot , I would do a rad./ cooling system test with a presshure  gauge , it will tell you if you have any leak
any place , that is the next thing I would do . and if you wanted to  you could remove the thermastat for the summer , that should cool it down by 10 deg. and is the schrowd on the car - is the fan close enough to the rad. ? and  see if anything is blocking the rad. etc.  ok
did you check to see if any hoses are getting sucked close when the engine is running ..
