What do cylinder head bolts do in car?

Cylinder head bolts clamp the cylinder head and cylinder head gasket to the engine block.

They are instrumental in sealing the engine so it can maintain the correct combustion ratio.

How does a cylinder head bolt work?

Cylinder head bolts are designed to create the correct degree of pressure on the head gasket and to create a reliable connection between the head and engine block.

When properly torqued, cylinder head bolts assist in:

  • containing the combustion pressure in the engine
  • sealing the coolant and lubrication channels.

Cylinder head bolts have a degree of elasticity, which gives them the optimal clamping force.

At installation, the bolts must be tightened to a specified torque value. They must be tight enough to create a reliable seal. However, if they’re tightened too far, it can compromise their integrity and pressure could cause them to fail. This could result in damage to the cylinder head.

For details on how to tighten conventional and torque to yield cylinder head bolts correctly, see the article, Tightening Engine Bolts, the RIGHT way.

Cylinder bolts with any signs of damage should be replaced immediately. Once disassembled, old bolts shouldn’t be reused. Instead, replace them with new bolts.
