Replacing oil lines - do support stud too?
 

I am replacing the oil lines between the thermostat and engine/oil tank. There is a support piece that holds them close to the body. It uses this threaded stud to tie them down.

Its starting to rust so I want to replace it. Does this just screw out? I tried using two nuts to unscrew it with no luck. I didn't want to ruin its threads with a vice grip until I was sure I am doing the right thing. What would you do?

Double nut it and back it out. Use PB Blaster first, give it a good soak.

I wouldn't open that can of worms. Threads don't look bad, clean it up with a wire brush, and coat it with never-seize when you put it back together.

I believe it is welded.

In that case, you will need a very LONG-handled wrench to twist it off. Just kidding. Clean up those threads, coat them with anti-seize and you'll probably never have a bit of trouble with that stud for the rest of your life.

I agree....don't mess with it.

Its back together with new oil lines and they look great. Forgot to take a pic of them before I put the wheel back on though.

I agree with the posts that this screw should not be messed with. In trying to back it out I stripped some of its threads and even had a nut stuck on it (did all that before I saw the later posts to this thread). Fortunately I did have the foresight to put the nuts on a portion of the threads that are not needed. So I used a dremel tool to remove the nut, scraped the rust off the stud and put primer and paint on it. I know, threading a nut on this will remove the paint. But the deeper threads should still be protected. One of the pics shows the slight gouging from the dremel. Also I cleaned things up a bit. :)
