Do you put anything on head bolts?

Yes. For head BOLTS you always dip them in oil.

What is the best sealant to use on head bolts?

Loctite Headbolt & Water Jacket Sealant is a single-component anaerobic hybrid that lubricates fasteners during assembly, as well as seals the gaps between the threads. It eliminates corrosion, which can cause difficulties if future disassembly is required.

Do you put threadlocker on head bolts?

no thread locker but you need to put gasket maker around the head of the bolt before you thread them in and tighten them. Its so coolant doesn’t seep out around the bolt shoulder.

Should I use anti seize on head bolts?

There is one time you should always use anti-seize when torquing cylinder head bolts: when it’s a diesel engine. As a rule, you need to chase both the male and female threads and use anti-seize on diesel engines.

Do you need to put Loctite on head bolts?

NO! You can use blue locktite in alot of places, but your headbolts are not one of them. Headbolts need to be brought up to torque specs in stages, and in a specific order (see a motor manual), and then re-torqued after the engine has been run for awhile to make sure they are all at the proper torque value.

Dirty or deformed hole threads in the engine block can reduce clamping force the same as dirty or damaged threads on the bolts. Run a bottoming tap down each bolt hole in the block. The tops of the holes

What should head bolts be lubricated with before installation?

As a rule, the threads and underside of the head on most standard automotive head bolts should be lubricated with motor oil before the bolts are installed. The torque values specified by the engine manufacturer are typically based on oiled threads and fasteners – not dry fasteners.

Can you use a die to recut head bolts?

On aftermarket studs or bolts, never use a die to recut the threads. Most have “rolled” threads, which are stronger than standard threads. Use a thread chaser to clean up the threads. 2.
