Greetings, my brothers, I have a 2012 model G25, during this time I faced a problem with the car’s temperature when using the car and the air conditioner. The car does not heat up a little, but when the air conditioner is turned on, the temperature returns to normal, but when the car is pedaled it rises slightly with the air conditioner turned on, so what is this problem! For information, you have changed fans and changed thermostats, so what do you think is the problem?

 

Check belt and tensioner also if you recently changed rad fluid might need a burping

 

I CHANGE

1- SONSER TEMP ( NEW )
2- RADITOR ( NEW )
3- CONDECSOR FOR A/C ( NEW )
4- THORMOSTAT ( NEW )
5- 2 FAN AND OEM Cooling Fan Control Module ( USE )

 

Sounds like a potential air bubble. Make sure to bleed and burp the system as best you can
