Should you use anti seize on exhaust 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.
How to get rid of stuck exhaust manifold bolts?
Learn how to remove stuck exhaust manifold bolts or studs. Wades shows you a little-known trick to help loosen up some of those old, seized and corroded exhaust manifold bolts. This can be a life saver tip and is a very common problem for gas and diesel applications.
Do you need to use anti seize on exhaust manifold bolts?
Although there’s no real need for applying anti-seize, it can rarely hurt as these types of repairs are often done several times throughout the life of the vehicle and with a lucky draw of the card, you might just be the one to do it again. Why did your bolt extractor break?
What kind of grease to use on exhaust manifold bolts?
For example, automotive formulas may contain aluminum, copper and graphite which are combined with grease. These formulas work great in high temperatures with copper and graphite combined with a high-quality grease, for example, on hot engine fasteners and bolts.
What should the temperature of the exhaust manifold be?
The exhaust can reach 1,000 – 1,200 degrees under a heavy load and even higher on integrated turbochargers and at high throttle. Different formulas are engineered to withstand different temperature levels.

What’s the best way to heat an exhaust manifold?
A faster option to the block heating method is to heat the exhaust manifold bolt itself and then cool it quickly. To do this, use your torch on the bolt head, getting the stud as hot as possible without changing its shape. Next, use a pair of tongs to hold an ice cube on the heated bolt (there will be hissing, steam and spluttering).
How long does it take to remove studs from exhaust manifold?
You will have to work quickly before the heat transfers from the engine block to the bolt. This process also takes a bit longer, as you will need to let the engine block cool before repeating the process for the next bolt.
What happens when you break the head off an exhaust bolt?
Once that bond is broken, the penetrant can get in between the threads and work it’s magic. If you get impatient and break the head off the bolt, one of two situations happens: either there is a bit of the bolt sticking out, or there isn’t.
