Have a 99si. Aem cam gears,short ram and fuel rail. Greedy evo exh. and dc headers. When the temp is about 85 or higher and my ac on. My car runs hotter than normal. If I turn the a/c off or drive, the temp returns back to normal. My radiator fan does come on when the temp is on the rise. I have replaced the coolant and the thermostat. Any info on this.
