The easiest way to install new exhaust flange bolts into an old, rusty exhaust manifold, without using vice grips, or pliers of any kind, and without damaging the threads on the new bolts.
Thanks for posting this...as many have said, this is a very old technique for installing a threaded stud. However, not all people looking things up on RU-vid are seasoned experts and know all these techniques and tricks. And, BTW, your explanation and filming was great. Some of the "experts" are so spastic, both verbally and with their camera, the content is practically worthless. You did great.
If your bolt doesn't spin easily it's because the threads are messed up. If you look closely there's 1 of the threads that he stripped hanging on the stud when he removed it. This video should be called how to cross thread. Just go get a proper tap smh 🤦🏽♂️
Just run a tap through the manifold side, then you can spin 'em in by hand. The studs are interference fit on the nut side so it'll bottom out the stud when you torque down the nut. And don't forget the nickle antiseize on everything, making it easy on the next guy is a good idea, since it's usually you.
Certain brands don't tap their bolts correctly and call it an interference fit... Tap the bolts as well or have fun drilling them out again after following the brands "directions".
Thanks for shairing. Helped me out. now off to get new studs and nuts. I was lost. Did not want to get New Cat very expensive. You saved me aton of Money. I am Very for youre expert Advice. Bill in New Jersey
Wow, that is incredibly simple and effective thank you. I would have struggled greatly trying to screw this in with one nut. My turbo lost one of its flange studs while I was taking out the catalytic converter on my Audi A4 b8.5. was semi concerned how I was gonna screw it in. Off I go to install my new test pipe!
Awesome thanks. Changing the gasket on a 67 mustang and the nut was cross threaded. Old stud came out instead of the nut coming off so I'm changing hardware. Never done studs that don't have a head to wrench on
Yes, as long as the nuts are tightened enough together, and it wouldn’t hurt to use some penetrating oil where they screw into the manifold/header, especially if they are rusted in
I used a pair of vice grips to grip onto the old studs, and a hammer to tap on the vice grips in a counterclockwise rotation to break them free due to them being rusted into the exhaust manifold.
at 1:45 he says " what I've come up with " ...as if it is your invention .!!!! the technique is called the " double nut technique ".... used by any mechanic who knows what he is doing ..!!!...anyway great video , clear pics and audio
