    check waterpump pressure, if ok, make sure fan is operating correctly, make sure your thermostats are opening when they should, if so get a temp gun measure top radiator hose and bottom if there is not a 30* differance your radiator is clogged and you need to remove and clean, if it is overheating slowly ( taking time ) it sounds like you have a radiator problem

    The newer style Horton fan hubs also have a tendency to start slipping after awhile, so the fan isn't drawing as much air through the radiator
