Can you replace exhaust manifold studs with bolts?
Table of Contents
Super Moderator. I agree, the bolts in place of studs and nuts would be okay. Be sure to observe the torque specs for the bolts, i.e. to be the same as the nuts on the studs. You dont want an exhaust manifold to be too tight – it interferes with the manifold expanding at a different rate than the head.
Are studs better than bolts for exhaust manifold?
Main studs Studs provide the ability to obtain much more accurate torque values because the studs don’t twist during tightening as do bolts. Because the studs remain stationary during nut tightening, the studs stretch in one axis alone, providing much more even and accurate clamping forces.
Are all exhaust studs the same size?
Registered. The studs and nuts are NOT the same, but they are the SAME thread size and pitch.
Can you reuse exhaust manifold studs?
You could reuse them, if you think they look good, but your chances of one breaking later have gone up now. I replace them every time, just heat the area around the studs, and melt a candle or crayon into the threads, let cool, they should come out easy, may need to heat again.
Can you use regular bolts for exhaust flange?
The usual options of exhaust flanges are the 3 bolt or 2 bolt types. Usually, m10 with the 2 bolt option is helpful, and an m8 bolt for the 3 bolt. The recommended grade of bolts is 8.8 tensile or higher so that you can tighten them without stretching or breaking the bolts.
What can I use for exhaust manifold studs?
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 studs?
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.

Can an exhaust manifold warp?
The exhaust manifold often warps and cracks, breaking off the studs between the cylinder head and the exhaust manifold. The noise may be most noticeable when the engine is cold.
What are Grade B16 stud bolts made of?
They are manufactured from a chromium-molybdenum-vanadium alloy steel, Although A193 Grade B16 bolts and studs have similar strength requirements as Grade B7, the fasteners retain strength under high temperatures, and also experience less relaxation at those high temperatures. There are two nut combinations you can use for B16 stud bolts. They are:
