1993 Acura Integra Radiator problem

Hi I was wondering.... my car lately hasn't wanted to start first thing in the morning (I live in AZ so it's not cold). I have to hold the key for a few seconds and then it will start. Also my A/C has recently taken a crap on me. So I was driving the car today and noticed a smell and at first thought it was freon. Then I realized that it was radiator fluid I was smelling and looked down at my temp gauge and it was past the red line on the hot. So I probably need to replace my radiator as it is the original factory radiator still in the car. My question is.... would the radiator problem have anything to do with it not wanting to start and my ac not working all of a sudden? My ac used to blow ice cold like a week to two weeks ago.

Thanks,

Misty
