Are you losing any coolant?

 

no i don't think so...........i checked the coolant every time before i start the car... and the coolant always full in the radiator........machanic and i didn't see any leaks in there.....but this only happen when i turn on the a/c.......over 30 mins or traffic stuck it will happen in the 2 pic that ur guys saw... if i didn't turn on a/c the temperature is normal (2 pic) just don't know why...............

 

It sure sounds like the radiator fan is not always turning ON when it is supposed to.

 

yea....but..... the fan will turn on but i'm not sure was it the right time on something i really don't know......i aw the fan is working but is there any realate about the radiator fan???

 

Does putting a jumper wire across the coolant switch connector located on the thermostat housing prevent the overheating when the A/C is ON?

 

i never try to put the jumper wire when the a/c is on... but i tried to put a jumper wire to the switch connector nd the fan still keep going............

 

anybody can help me out.. or have some pro mechanic recommand in southern california???

 

Do what Ron suggested, put in a jumper wire and test-drive with the A/C on. Fan should be running all the time with the jumper in. If it stays cool then, replace the thermal switch.
