My Honda got a new radiator a little over a month ago. Its temp has been running normal, but the weather has been nice and cool. The weather just got a little warmer and I started to use my air conditioning. My Honda started running about 2/3 of the temp guage, pretty hot. And when I use my air conditioner it gets almost to the red zone. I know the trick of running your heater to cool the engine down fast so it hasn't done any damage, but what is causing my engine to overheat?

you may need to replace your thermostat and you may need to add coolant it should be 50/50 ( coolant to water)
