How do I replace 4 speed auto lower cooling line? Thanks to who reply.

 

I would think a Haynes or Chiltons repair manual would have the information you would need.

One bit of advice: Where those lines run past the idler arm bracket where it attaches to the frame make sure they are far from the sharp corner of the upper end of the bracket. I had one of my lines almost wear through. Once replaced, I wrapped a short segment of flexible hose over the line to protect it.
