The cylinder head bolts ensure a tight fit of the cylinder block and the cylinder head, due to the cylinder head gasket performs its function efficiently - it protects against the leakage of oil, coolant and counteracts internal pressure and high temperature. Tightening the cylinder head is an important and responsible procedure. This operation is performed during the reassembly of the engine after removal. Correct tightening of the cylinder head bolts affects the health and performance of the power unit, since the head is part of the combustion chamber. In other words, once tightened, the cylinder head is integral with the cylinder block. An additional sealing gasket is installed between the block and the block head. In the event that the head is not tightened correctly, there is a high probability of damage to the cylinder head itself, car bolts and bolt holes. In some cases, leaks appear at the installation site of the gasket. Also, in the case of a loose fit of the bolt head screws during operation, exhaust gases may burst into the channels and the engine, and antifreeze also gets into the oil and vice versa. As a result, the properties of the lubricant and coolant change, which can quickly damage the engine. The need to replace the cylinder head bolts arises in the event of their wear (as a rule, in the case of frequent assembly and disassembly of the engine) or in case of poor-quality installation. In this case, the following can occur: destruction of bolt threads, pulling out of the bolt body, changing its original shape, violation of the shape of the bolt head edges, destruction of washers.
