I recently got my A/C done on my SR and I was so happy about it until this overheat issue came up. I will be running on the highway with A/C on, and as soon as I hit boost like the 5th time, the stock temp gauge will rise up to H. I check to see if there are any air in the coolant, does not seem so. So, is this a common problem or I do have a problem?

when you put in the altima fans, did you ditch the stock electric fan? cuz that's for the a/c condenser.

I think altima fans are dual speed? make sure they arent running at the slow setting.

The stock fan is gone that's why I set my fan to come on lower temp so it can cool the condenser. But anyways, I will drain the radiator within this month. I will use a 3 to 1 water/coolant mixture and also water wetter from redline to see if it helps.

I will check which setting the fan are operating later this week. But about how fast do the run at high speed compare to low?
