    Buy a noncontact thermometer(infrared) at Home Depot and such and take reading of the upper and lower temp at the radiator metal. There should be no more than a 10 degree difference. I suspect you have a bad radiator.

    3.4L Engines have a bit of head gasket trouble. Have a combustion leak test done.
