I feel like a fool for asking this as there is probably a simple solution, but I just can't figure it out. I'm trying to remove the two tranny cooler lines from the radiator, and have loosened the flare nuts as far as I can with a wrench. They are just spinning, but they are still grabbing and the line won't disconnect. The cooler tube moves forward and back so it's not stuck, but I just can't get the flare fittings to come out. I have tried pulling on the lines while turning the wrench, but no joy.

Anyone run into this before? I'm tearing down the truck for a basic restoration and this is keeping me from getting the radiator out. I'm getting ready to reach for the hacksaw, so any help would be appreciated. Thanks!

 

You should be able to pull back on the line, and turn the nut with your fingers. Keep turning it and pulling on it at the same time with your fingers.
