How do you remove a rounded exhaust manifold bolt?
from Berry, AL. I'd try to weld a nut on it first, then shoot the bolt and manifold with PD Blaster or your favorite penetrating oil. While it's still warm, whack the end of the bolt with a hammer a time or two, then using a six point socket, try to loosen it a bit, then tighten it a bit, then loosen a bit, etc.
How do you loosen a bolt that won't budge?
Try a 6-point wrench or socket on your seized nut/bolt. Start by rocking the bolt by tightening then loosing, this may be all you need to break through the rust. Try and avoid 12-point wrenches and sockets as they likely to slip and strip the bolt head. http://www.irwin.com/tools/locking-tools/the-origi...
How do you remove a seized bolt without a head?
Just spray on the rust remover on the head of the screw and bolts but make sure that the product steeps into the threading. After steeping the screw and bolts for 10 minutes, you can attempt to disengage it.
How do I remove a stuck catalytic converter bolt?
Proven Member. I have used a lot of PB blaster along with a lot of force to break them loose. I used a nut splitter to cut off the nuts on the studs on the back of the cat. Heating the nuts/bolts with a torch until they turn red and then use a breaker bar on them works well too.
Does wd40 loosen bolts?
If the bolt is stuck in place because of rust, you can use a bolt loosening spray such as WD-40 Penetrant Spray. This penetrating oil provides deep lubrication to loosen the nut or screw.
What causes manifold bolts to break?
Each duty cycle will provide tension stress on the studs or bolts that hold the manifold in place. ... This expansion and stretching of the manifold bolts over numerous duty cycles eventually causes too much tension on the bolt(s), stretching them beyond capacity and causing them to fail.
Should you use anti seize on exhaust manifold bolts?
If you are reusing exhaust manifold bolts (which we don't recommend), apply a metal fortified anti-seize to your manifold bolts. If you've just removed the broken bolts and ready to complete the repair, chase the threads clean and use fresh OEM bolts for best results.
