Repairing ground/earth points

[johnhedge]

Hi,

I'm staring at at least 2 ground points in my empty engine bay. They're rusted to ...

I've tried putting a spanner on them but the nut is now totally rounded. If I put much more effort/strength into their removal they're likely to disintegrate entirely.

Any/all suggestions welcome, please.

TIA

John

Hello, have you tried a dremel/die grinder to remove the fastener? Including a picture might help. Good luck.

Funnily enough I bought a Dremel a few days ago. I haven't used it yet.

I tried to upload photos before but I'm a noob. I couldn't find out how to do it! I'll try again.
Easy as! I'm not sure why I couldn't do it before.

My Dremel is only a couple months old. Love that thing.

Your joint seems to be a weld stud and nut. Do you have Vise Grip pliers? I would try that first. You want to make sure you don't hurt the ground stud threads. You only want to replace the nut.

I totally agree. I do have a vice grip but I'm concerned about breaking the stud. The cable attached has no extra length either so I can't afford to damage it by using heat!

Quite a conundrum.

Yes, a conundrum. Have you checked the resistance with a multimeter to ensure it's a bad ground? Maybe leave it alone, if the resistance if ok? Hopefully somebody has run into this problem and can advise further.

Try one of the higher-dollar penetrating oils? Kroil is very well regarded; you can get it from McMaster-Carr.

I'm going to try a product called Freeze and Release. I'll report back as to my results.

Patients and penetrating/rust oil. Sometimes helps to clean out down around the first thread w a pin or the like. If you get a good grip w anything, do small loosening and tighting movements, keep soaking it, even light tapping to gradually break the rust seal.If there is a way do small cut in the side of the nut u can use a hammer/ small chisel or screwdriver to gently " chock" it both ways.

Freeze and Release by Loctite plus vice grip did the trick!

Glad you got it off. Is "Freeze and Release any different from other penetrating oil products?

Wurth makes a similiar product which I have used with great results, didnt know loctite got in the game! It freezes the part which allows the oil to penetrate..
