The cylinder head is a critical component. Elements of the fuel supply and removal, timing elements, etc. are mounted on it. In order for the cylinder head to perform its protective function in full, it is necessary to ensure its secure fit, a special bolt is responsible for this work. This connecting element allows the required force to be generated for the double sealing of the combustion chamber, engine oil passages, cooling water and ambient air.

The usage of the TOPRAN brand Bolt Kit, cylinder head

The connection must remain stable and reliable in all conditions - at low or high pressure, at low or high temperatures. These bolts are selected according to the dimensions that are inherent in the given car brand. Different types of connecting elements can be installed on different car models, which differ in both the material of manufacture and the type of thread

Replacing the cylinder head bolts must be performed continuously when removing the cylinder head. The fact is that the cylinder head bolts stretch over time and even in the absence of visible deformation, it is worth replacing them. Metal fatigue of used bolts can be more serious.
