Can I use bolts for exhaust manifold?
Just consider the application. 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.
Should you replace exhaust manifold bolts?
In addition, we recommend replacing all of the bolts with OEM mounting bolts or studs. When you replace the manifold with a new one, it will be prone to the same warping that broke the bolt originally – so at the very least, be sure to replace all of the bolts with OEM mounting bolts or studs.
Do exhaust manifold bolts need anti seize?
You should use anti-seize on all the bolts on your exhaust system, intake manifold, and any steel bolts that join aluminum or another metal different from the bolt. It is recommended to apply anti seize to any bolts prone to seizing.
What causes broken exhaust manifold bolts?
That rapid heat causes the exhaust manifold material to expand, which puts a tremendous strain on the bolts and/or studs holding the manifolds to the cylinder heads. After hundreds of expansion and contraction cycles, the studs or bolts finally fail. It’s not too dissimilar from bending a paper clip back and forth.
Can you use stainless steel bolts exhaust manifold?
SS bolts on an exhaust are a good idea – they will last significantly longer than standard bolts. They’re relatively unstressed. It’s a good idea to put some grease or oil on the threads to prevent galling as you tighten the bolts down as SS is a little softer.

Why are exhaust nuts copper?
Is there any advantage in using copper nuts on the exhaust manifold to head bolts? yes, copper nuts don’t rust/seice-up. And they are self-locking. There is a downside to, they deform easier so you need really well fitting tools.
When should an exhaust manifold be replaced?
It requires changing if its tightness is compromised due to cracks and deformations. How is the manifold replaced? The exhaust manifold must be replaced if the engine is removed from the car. In older cars, removing the screws fixing the manifold to the engine block may be difficult as they may be corroded or stuck.

Do I need special bolts for headers?
Most headers with 1/4-inch or 5/16-inch thick flanges will use bolts with a 3/4-inch UHL, while 3/8-inch thick flanges normally require bolts with a 1-inch UHL.
What are copper nuts used for?
What are Locknuts used for? A copper lock nut really becomes useful when mounting a turbo to manifold or manifold to engine cylinder head, these can also be used as a general locking nut for all components.
How long does it take to replace an exhaust manifold?
Usually, this type of repair will run between two and three hours. Most independent shops charge around $80 to $90 an hour, so it should cost between $160 and $270 in labor. At a dealership, with a labor rate of approximately $110 an hour, you can expect a labor bill of between $220 and $330.
