Okay so I've installed in my RSX I mishimoto racing thermostat which opens at 140° as opposed to 170ish with stock. I also have a dual core radiator that holds a hell of a lot more coolant and also I mishimoto fan switch which engages at 180 and shuts off at 165 for the temp. No I love the temps on normal drives it doesn't really get above 188ish even with a little bit of throttle play. However with the AC on and sitting or idling for a period of time the temp will climb to upwards of almost 220 if I let it. My question is do you think that the dual core radiator is just too much coolant or should I also upgrade my fans?
