over heating issue (40th 370z GTM TT KIT)

hindi1973

when the ac turned off it cooled down abit, but icouldnt stay much longer so i left it was too hot , but i cant say that its overheating but i dont know where will it stop if it would have !! i saw it jumpd 2-3 dots passed the normal range when i saw that and i turned off the ac to see wht will happen , and it cooled down so i switched the car off .

later at night i did the same thing with the ac on for an hour and nothing happened . it was in the middle all the time .it means nothing was wrong
but the qustion here is !!! why did it jump 3 dots then ? was it because it was too hot ? is it true the all twinturbo cars are not ment to be in very hot climates?? or is it a technical thing that comes and goes!! but still it wasnt tooooooo hot we are still in april , the max it could have gone is 38-39c , in august where am from it reached 55-60c EAZEEEEEEE!!
that means i cant even ride the car no more , so something must be done and checked , if u read u will notice i already changed a couple of stuff , but maybe i need to do some other check ups and changes .
ill keep u guys updated so all of your guys in hot climates know whts up .
