Recently I have been getting high engine temps but only with the AC on. The coolant gauge will read 189-194 without actually and will go as high as 232 with AC on. Driving around will keep the temps between 219-225. But once stopped like in traffic it will go up to 230. The weather outside is hot and this is the first time I have driven this car in the summer. Temps here are around 100 to 111 most of the summer. Which leads me to believe that it might just be the weather in my area. At night it will only go as high as 214-216 with AC on. The fan seems to be going full speed whether the AC is on or not. It is setup to start the fan at 100% at 200 degrees with hp tuners.
