Hi all
My wife just told me that her 06 g35x is not giving off heat when the car stops on a light. Heat turned on to 90. I checked it out for her the other day. I made sure that i checked coolant level. It was a little low so i put more in. I drove the car till it warmed up.
When i came to a light the car wouldn't give off warm heat. When i started driving it would warm up but not to 90 degrees like the dial was set to.
Any ideas what the issue might be?

Thanks

 

So I have had this issue myself. The problem most likely is you have air in the cooling system, take it to a dealer and have them "burp" the air out of the system and it should solve the issue. If your car temp is fine then the thermostat is probably just fine. Heat would be fine for me while accelerating then blow cold air when it was stopped.

Good Luck!
