    Hello,

    Is there a trick to removing the transmission cooler lines from the radiator?

    Thanks!

    Flare nut wrenches are your friend, (the kind for brake lines) Plus a little spot of torch heat as the tube can rust up solid to the nut as it looks like yours already has by looking at the twisted collapsed tube. Just a quick spot of heat on the nut before you turn it should free it of the rust bind.

    Hitting the connector with a shop of good penetrating oil also helps.

    One trick I learned from a friend is to lay a hammer against the flat on one side of the hex and rap the opposite side with another hammer. Works almost every time.

    That said, that line is toast.

    You hold the brass part with a 1/2” open end. You turn the large Nut with a 5/8” wrench. Go back and forth if it won’t spin on the tube.

    looks like an aluminum rad. Also looks like it has been sprayed with something.

    Just twist it out/snap the line. Throw it away and replace with female brass inverted flare. Then use 3/8 line with regular male nuts on the line. Next time you will be able to use 2 flare wrenches.
    Not one of Chryslers better ideas, but what do they care they don't have to work on rusty cars only new.
    I do like the double hammer idea from Big John. Have to try that on my Challenger on cam swap.
