Frequently Asked Questions (FAQs)
1. What type of bolts are used on cylinder heads?
Head bolts are used to fasten the cylinder head to the engine block in internal combustion engines. They can also be used to attach other parts of the block, such as camshafts, timing chain covers, and oil pans.
2. What is better head bolts or studs?
Studs are generally considered better than head bolts because they are less likely to twist while being torqued, resulting in a more consistent torque loading. However, head bolts are less expensive and more suitable for installations with clearance issues that would prevent the use of studs.
3. How much torque do you need for engine head bolts?
For engine head bolts, each bolt should be tightened to a torque of 12-15 foot pounds.
4. How many times can you reuse head bolts?
Standard head bolts can be reused multiple times as long as they have not been stretched past their spring back point. Head bolts are designed to stretch when torqued into place and return to their original position when removed.
5. Should you grease cylinder head bolts?
In most cases, the threads and underside of the head on standard automotive head bolts should be lubricated with motor oil before installation.
6. Why do people upgrade head studs?
People upgrade to head studs because they provide a greater clamping force compared to head bolts. This increased clamping force helps seal the cylinder head, head gasket, and engine block together more effectively, allowing the studs to withstand higher power levels.
7. What happens if you don't torque head bolts?
If head bolts or studs are not tightened enough, the cylinder pressure in the engine can cause leaks between the cylinder head and block, leading to coolant or combustion gas entering the wrong channels and potentially causing engine damage.
8. Should I torque the nut or bolt head?
Whether to torque the nut or bolt head depends on the application and the condition of the materials being fastened. In many cases, torque can be applied to either the nut or bolt head, as both will result in a tight connection. The choice between the two does not significantly affect the risk of breakage.
