I finally got my AC fixed but noticed my temps got pretty high. I turned off the AC at 106 C. Without the AC my car runs at about 86-90 C. I do have a Koyo and all ducting. After I shutoff the car I could hear the coolant noises coming from the turbos. I did notice also a hiss coming from the AST. So I'm going to replace that.
I would like to know what others are getting for the high temps with the AC on.

 

usully wit ac on my temps go down

 

Forgot to mention that outside temps where 94F

 

Then your car must be a freak of nature, because that is not how it works. It gets hotter as the comdenser is putting out hot air in front of the radiator.

 

When you turn the A/C on, it turns your fans on as well. Since the stock engine bay doesn't allow much air to flow through the radiator, running the fans will make up for the additional heat introduced by the A/C condenser.


When ambient temps are less than 90F, my car runs much cooler with the A/C on, even at 80mph. Temps will hover around 180F, which is the thermostat's opening temperature.

When it's hotter than 90F outside, my stock radiator isn't as efficient, and the fans only overpower the A/C at low speeds (under 60mph). At high speeds, turning my A/C on might raise coolant temps by 5-10F.
