Antifreeze leaking from overflow tank

    I live in Tucson, Arizona and today after work I cranked my '97 Dodge
    Grand Caravan and sat in the car with my wife for over an hour.
    During this time I had the car running with the airconditioning on.
    Someone walked by and told me that antifreeze was leaking from my car.
    I checked the temperature and it was in normal range. I popped the
    hood and could not find a leak, but saw that my overflow tank was
    almost overflowing. It was above the maximum amount. I also saw that
    there was some power steering fluid on top of the power steering fluid
    reservoir. The engine seemed really hot, even the hood prop was too
    hot to handle. Can anyone tell me what would cause this? After I let
    the car cool down for a while, the antifreeze in the overflow tank
    went back down to minimum. The van drove home fine without any
    problems. I should say that I think the 02 sensor is bad and the car
    seems to run lean. Any help would be great. Thanks!!!

    Are you sure that it was antifreeze on the ground and not just ac
    condensation which is normal?
    Sounds like your steering fluid might be over filled. Instructions on
    checking the level are in your owners manual.

    Maybe not enough airflow around the engine compartment. When the car
    moves all that surrounding sheet metal, hood fittings, latches, etc,
    stay cooler. I believe any vehicle that sits in one place for a long
    time with the AC on in hot weather is going to build up heat in the
    front of the car....,

    Yeah....I thought about the airflow, but I have a 2003 vehicle and it
    has never done anything of that sort. The van runs fine (other than
    the 02 sensor). I just found it odd because I thought antifreeze was
    not supposed to expand and yet it rose out of the overflow tank.
    Thanks for your guys' help. I will be doing some more investigation
    and post my results later.

    If it wasn't supposed to expand, why is there an over flow tank!
