We clean the surfaces of the head and block

We check the block head for warpage.

To do this, we put the ruler with an edge on the surface of the head, first in the middle along, then across and along the diagonals and with a probe we measure the gap between the surface of the head and the ruler.

We replace the block head if the gap is more than 0.05 mm.

Install the cylinder head in reverse order.

We tighten the bolts on a cold engine, in the order shown in Figure 17 in two stages:

- the first stage (preliminary) - tighten the bolts with a torque of 20 Nm;

- the second stage - we turn the bolts at an angle of 240 ± 5˚
